Bardo - Wikipedia, the free encyclopedia

Bardo - Wikipedia, the free encyclopedia: "The Tibetan word Bardo means literally 'intermediate state' - also translated as 'transitional state' or 'in-between state' or 'liminal state'. In Sanskrit the concept has the name antarabhāva.

Fremantle (2001) states that there are six traditional bardo states known as the Six Bardos: the Bardo of This Life (p.55); the Bardo of Meditation (p.58); the Bardo of Dream (p.62); the Bardo of Dying (p.64); the Bardo of Dharmata (p.65); and the Bardo of Existence (p.66).

Shugchang, et al. (2000: p.5) discuss the Zhitro (Tibetan: Zhi-khro) teachings which subsume the Bardo Thodol and mention Karma Lingpa, terma and Padmasambhava and list the Six Bardo:

In the terma discovered by Karma Lingpa, Guru Padmasambhava introduces six different bardos. The first bardo begins when we take birth and endures as long as we live. The second is the bardo of dreams. The third is the bardo of concentration or meditation. The fourth occurs at the moment of death. The fifth is known as the bardo of the luminosity of the true nature. The sixth is called the bardo of transmigration or karmic becoming.[1]"

Johnny Chung Lee - Projects - Wii: "Johnny Chung Lee > Projects > Wii

As of June 2008, Nintendo has sold nearly 30 million Wii game consoles. This significantly exceeds the number of Tablet PCs in use today according to even the most generous estimates of Tablet PC sales. This makes the Wii Remote one of the most common computer input devices in the world. It also happens to be one of the most sophisticated. It contains a 1024x768 infrared camera with built-in hardware blob tracking of up to 4 points at 100Hz. This significantly out performs any PC 'webcam' available today. It also contains a /-3g 8-bit 3-axis accelerometer also operating at 100Hz and an expandsion port for even more capability. These projects are an effort to explore and demonstrate applications that the millions of Wii Remotes in world readily support.

Any software on this page is primarily meant for developers and may not run without proper the development tools installed. Downloading and installing this software is at your own risk, and no support or guarantee is provided with this software.

Head Tracking for Desktop VR Displays using the WiiRemote

Using the infrared camera in the Wii remote and a head mounted sensor bar (two IR LEDs), you can accurately track the location of your head and render view dependent images on the screen. This effectively transforms your display into a portal to a virtual environment. The display properly reacts to head and body movement as if it were a real window creating a realistic illusion of depth and space. By Johnny Chung Lee, Carnegie Mellon University.

08Z1Z4TessReally: "When you told me that you were
going to show me a tesseract, I
thought you were going to point to a
stand-alone geometric figure, Steve."

A hypercube is not a geometric figure, but a collage of different sizes of cubes superposed on each other.
The numbskulls of relativity inadvertently have converted this ‘movie of an inflating cube’ into a static
‘solid.’ When Sagan says that he cannot show you a tesseract, it is not because we unfortunate 3-D
beings are stuck in Solidland. The reason has to do with the fact that we are not looking at a static
sculpture. We are looking rather at a statue that is getting bigger by the minute and we are attempting to
visualize it in a single frame of the film. The reason we cannot visualize or see a tesseract has nothing to
do with our limitations as 3-D beings. It has solely to do with the fact that relativists are presenting an
irrational hypothesis. The tesseract is its own contradiction, a self-falsification.

Hypercube

Hypercube: "Return to Drew's Home Page Hypercube

A friend of mine was reading a book about the fourth dimension and was having a hard time visualizing hypercubes, so I wrote a program so he could play with a hypercube interactively.

The user can rotate around the hypercube, or perform direct-manipulation rotations in 4D.

For a 4D rotation, the 3D vector described by the dragging of the mouse in the plane of the screen combined with the 4D unit vector (0 0 0 1) specify two basis vectors of a four-dimensional plane of rotation.

This is a lot more intuitive than a set of sliders.

Before I show an example of the 4D rotation, wrap your head around this simple 3D rotation of a regular old cube.



In the above sequence, the red square is the back face of the cube. It's smaller than the other squares because it's farther away from the viewer. As it the cube rotates around 90 degrees, the red square becomes a trapezoid.

Here's the hypercube. Instead of a bunch of squares connected together, it's a bunch of cubes all fused into a big weird mess."

Rotating 4D Hypercube

Rotating 4D Hypercube: "Rotating 4D Hypercube

Rotating 4D hypercube (GIF movie).

Imagine a person who lives in 4 spatial dimensions, watching a hypercube rotate. The 4-dimensional person has a 3-dimensional retina in each of its 2 eyes (two eyes suffice for depth perception, even in 4D). Each retina records a 3-dimensional image.

This image shows what the 4-dimensional person sees, with the extra dimension shown as a variation in colour. That is, the horizontal, vertical, and `colour' directions correspond to the 3 directions on the 3-dimensional retina of the 4-dimensional person. The vertical bar to the right of the picture shows the correspondence between colour and position in the extra dimension.

This is a `false colour' image, because the colour corresponds to something other than true colour. Of course our 4-dimensional friend undoubtedly sees in true colour as well...

The hypercube: Exploring the fourth dimension, and further

The hypercube: Exploring the fourth dimension, and further: "With apologies to those who know all about the hypercube, this is written for those who don't, to indicate the interesting shapes you can get in 3D by extending 3D mathematics into an imaginary fourth dimension. I first learnt of this from Prof. A K Dewdney's 'Computer Recreations' column in the April 1986 issue of Scientific American.

Let us imagine that another Big Bang created a 2D universe and we are 2D critters living in a plane world. We come to appreciate our position in relation to x and y axes at right angles, can perceive points, lines, squares and circles and can do Pythagoras. Our 2D mathematicians (2DMs) can rotate a point about the origin with two equations looking like 'SUB rot' in the QBasic code in Listing 1. As it rotates, the new x and y co-ordinates each depend on the old x and y, and the angle of rotation. We might consider that the simplest square has its corners at the four points (x,y) = (�1, �1)

Simulated reality - Wikipedia, the free encyclopedia

Simulated reality - Wikipedia, the free encyclopedia: "Simulated reality is the proposition that reality could be simulated—perhaps by computer simulation—to a degree indistinguishable from 'true' reality. It could contain conscious minds which may or may not know that they are living inside a simulation. In its strongest form, the 'simulation hypothesis' claims it is possible and even probable that we are actually living in such a simulation.

This is different from the current, technologically achievable concept of virtual reality. Virtual reality is easily distinguished from the experience of 'true' reality; participants are never in doubt about the nature of what they experience. Simulated reality, by contrast, would be hard or impossible to distinguish from 'true' reality.

The idea of a simulated reality raises several questions:

* Is it possible, even in principle, to tell whether we are in a simulated reality?
* Is there any difference between a simulated reality and a 'real' one?
* How should we behave if we knew that we were living in a simulated reality?"

Cube 2: Hypercube - Wikipedia, the free encyclopedia

Cube 2: Hypercube - Wikipedia, the free encyclopedia: "Cube 2: Hypercube is the sequel of the science fiction/horror movie Cube. Released in 2002, Hypercube had a bigger budget than its predecessor, and a new director, Andrzej Sekuła.

The industrial-style rooms of the first movie are replaced with high-tech, brightly-lit chambers; the plausible technology of the traps—flamethrowers and extending spikes—are replaced with floating objects with razor-sharp blades and translucent walls that decompose matter. The Cube Rooms, that the main Cube is composed of, are not separate entities that move but simply the same Cube in different times. Different chambers inside the tesseract also distort gravity, time and space, leading to alternate realities."

A New Era of Thought - Wikipedia, the free encyclopedia

A New Era of Thought - Wikipedia, the free encyclopedia: "A New Era of Thought is a non-fiction work written by Charles Howard Hinton, was published in 1888 and reprinted in 1900 by Swan Sonnenschein & Co. Ltd., London. A New Era of Thought is about the fourth dimension and its implications on human thinking. It influenced the work of P.D. Ouspensky, particularly his book Tertium Organum where it is frequently quoted. Scientific American writer Martin Gardner mentioned this book in some of his articles. [1] A New Era of Thought also had impact on Rudy Rucker's book The Fourth Dimension (book). [2] It is prefaced by Alicia Boole and H. John Falk. A New Era of Thought is inspired by Plato's allegory of the cave and is influenced by the works of Immanuel Kant, Carl Friedrich Gauss and Nikolai Lobachevsky. The book has xvi and 230 pages."

SO(4) - Wikipedia, the free encyclopedia

SO(4) - Wikipedia, the free encyclopedia

In mathematics, SO(4) is the four-dimensional rotation group; that is, the group of rotations about a fixed point in four-dimensional Euclidean space. The name comes from the fact that it is (isomorphic to) the special orthogonal group of order 4.

In this article rotation means rotational displacement. For the sake of uniqueness rotation angles are assumed to be in the segment [0,π] except where mentioned or clearly implied by the context otherwise.

Tesseract - Wikipedia, the free encyclopedia

Tesseract - Wikipedia, the free encyclopedia: "In geometry, the tesseract, also called an 8-cell or regular octachoron, is the four-dimensional analog of the cube. The tesseract is to the cube as the cube is to the square. Just as the surface of the cube consists of 6 square faces, the hypersurface of the tesseract consists of 8 cubical cells. The tesseract is one of the six convex regular 4-polytopes.

A generalization of the cube to dimensions greater than three is called a “hypercube”, “n-cube” or “measure polytope”. The tesseract is the four-dimensional hypercube, or 4-cube.

According to the Oxford English Dictionary, the word tesseract was coined and first used in 1888 by Charles Howard Hinton in his book A New Era of Thought, from the Greek “τέσσερεις ακτίνες” (“four rays”), referring to the four lines from each vertex to other vertices. Some people have called the same figure a “tetracube”, and also simply a 'hypercube' (although a hypercube can be of any dimension)."

Match moving - Wikipedia, the free encyclopedia

Match moving - Wikipedia, the free encyclopedia

In cinematography, match moving is a visual effects technology to allow the insertion of virtual objects into real footage with the correct position, scale, orientation and motion in relation to the photographed objects in the scene. The term is used loosely to refer to several different ways of extracting motion information from a motion picture, particularly camera movement. Match moving is related to rotoscoping and photogrammetry. It is sometimes referred to as motion tracking.

Match moving is distinct from motion capture. The latter is a technology for recording the motion of objects, often human actors, in a controlled environment with special cameras and technology. The former is a software technique applied to normal footage that can be recorded in uncontrolled environments with ordinary cameras. This article defines match moving as the art of extracting motion information from actual footage, where additional cameras, motion capture sensors, and motion control photography are not necessarily used.

Match moving is primarily used to track the movement of a camera through a shot so that a virtual camera move can be reproduced by a computer system. The intent is that when the virtual and real scenes are composited together they will come from the same perspective and appear seamless.

Match moving is now an established visual effects tool.

The Story of Power Rangers

Writer's Guide to the PR Universe - The Story of Power Rangers:

	One day in 1993, two astronauts free the space witch Rita Repulsa. Earth's only hope lies in five teenagers from Angel Grove when the extradimensional sage Zordon equips them with Power Morphers and giant robots known as "Zords." Together, the Power Rangers fight evil while maintaining double lives as ordinary high school students.
	Numerous defeats later, Rita chooses Tommy Oliver as her evil Green Ranger. The Rangers soon break Rita's spell over him and add Tommy to their ranks. Her creations no match for the six Rangers, Rita ultimately drains the Green Ranger's powers with a magical candle.
	But when the Rangers forfeit their powers to rescue their parents from Rita's Dark Dimension, Tommy returns to save the day, using temporary powers drawn from Zordon and the other Rangers. Now reunited, the Rangers thwart Rita time after time. Until...
Rita's master Lord Zedd returns and banishes her into the depths. The Rangers, meanwhile, upgrade their Dinozords into Thunderzords to battle Zedd's new army of monsters. Tommy's powers are exhausted, but he soon returns as the White Ranger.
Just as Zedd completes his massive war machine Serpentera, three of the Rangers are selected for a peace conference in Switzerland. Rocky, Adam, and Aisha step forward as their replacements, and Zedd is dealt numerous losses at the hands of the new Power Team.
Later, Rita returns to Zedd's moon palace and weds the master of evil using a love potion. The Rangers escape each of the couple's nefarious plots, but then disaster strikes...
	Rito, Rita's brother, manages to destroy the Thunderzords in battle, overloading the Rangers' powers. They seek out the ancient sage Ninjor, who equips them with new Ninja powers and Zords.
	In time, Rita turns Australian-born Kat Hillard into her evil double agent, resulting in the loss of Pink Ranger Kimberly's powers, as well as Ninjor and the White Ranger's Falconzord. Kat later breaks free from Rita's control and becomes the new Pink Ranger as Kimberly retires to pursue a gymnastics career.
	Soon, Rita's father Master Vile arrives seeking the long-hidden Zeo Crystal. Although the Rangers scatter the crystal through time to keep it from Vile's clutches, the evil sorcerer reverts the Rangers to children. Their Power Coins destroyed, the ex-Rangers seek the Zeo Crystal while the Earth is defended by the Alien Rangers of the planet Aquitar.
Once the crystal restores time, the Rangers, now joined by new Yellow Ranger Tanya, find their Command Center under attack. The Zeo Crystal survives, and the teens become Zeo Rangers, armed with new weapons and Zords against the threat of King Mondo's Machine Empire, whose forces have sent Rita and Zedd into hiding.
Some time later, the Rangers are aided by the mysterious Gold Ranger from the planet Triforia. But when the Gold Ranger is injured by alien bounty hunters, he leaves his powers under the care of former Red Ranger Jason, who rejoins the team in Angel Grove.
King Mondo soon falls to the might of the Rangers' new Super Zeozords, but Rita and Zedd's hopes to reclaim their moon palace are dashed with the arrival of Mondo's heir, Prince Gasket.
Mondo then returns, and the Rangers' situation seems bleak when the Gold Ranger powers begin to fail. Just then, Trey of Triforia reclaims his powers; Mondo is defeated, and Rita and Zedd finish off the strained Machine Empire.
	Peace doesn't last long as the evil space pirate Divatox arrives seeking to release the lava demon Maligore from his island prison. The Rangers, joined by the young Justin as the new Blue Ranger, upgrade to Turbo technology and defeat Divatox's schemes.
	Zordon soon departs for his home world of Eltar and is replaced by Dimitria of Inquiris. The Rangers are also joined in time by the Blue Senturion, a robot police officer from the future who brings news of an impending disastrous evil alliance.
	When the senior Rangers retire, they pass their powers to four worthy candidates. The new Rangers are aided by the mysterious Phantom Ranger and his new set of Rescuezords, which they use to thwart Divatox's brother, General Havoc.
When the evil overlord Dark Specter captures Zordon, the Rangers, recently defeated by Divatox's assault on their Power Chamber, fly into space as Justin remains on Earth. On their journey, the teens encounter Andros, a Red Ranger from the planet KO-35 who slowly accepts them as his teammates. Together, the new Space Ranger team defends Earth from the attacks of Dark Specter's agent, Astronema.
In time, Astronema is joined by the treacherous bounty hunter Darkonda, whom Andros discovers was responsible for his sister's disappearance years ago. The Rangers gain new Mega Vehicles hidden by Zordon, as well as a new teammate, the Silver Ranger Zhane, who awakens from a two-year cryogenic suspension. After a quest to restore his weakened powers, Zhane ultimately departs to rejoin his people, the survivors of KO-35.
When Astronema discovers she is Andros's sister Karone, she defects to the Rangers' side but is turned evil once more when Dark Specter turns her into a cyborg. In a plot to destroy both the Rangers and Dark Specter, Astronema unleashes the Psycho Rangers, who drain Dark Specter's energies until their eventual destruction.
But soon, Dark Specter declares war on the universe. With the likes of Rita, Zedd, the Machine Empire, and Divatox joining forces, the evil armies quickly overwhelm the forces of good. Finding herself ruler of the universe after Dark Specter is destroyed by Darkonda, Astronema engages in a final showdown with Andros. Ultimately, Andros shatters Zordon's energy tube, unleashing a wave of energy which decimates Dark Specter's armies and purifies Karone.
	With the Earth saved, a select fleet of colonists embark on a search for a New World aboard the massive space colony Terra Venture. But on the distant planet Mirinoi, the evil alien Scorpius attacks seeking the ancient Quasar Sabers. Maya escapes and returns with five teens from Terra Venture who join her in unleashing the ancient weapons. When their leader Mike falls to certain doom, the remaining teens and Maya become Galaxy Rangers and flee to Terra Venture as Mirinoi is left imprisoned in stone.
	Pursued by Scorpius, the Rangers defend the colony from his repeated attacks, which include a plot to unleash the ancient Lights of Orion. During this time, the Rangers also contend with the Magna Defender, who seeks the Lights to enact vengeance on Scorpius. The Rangers ultimately capture the Lights, and Magna Defender sacrifices his life to save the colony. His life force having been absorbed by the Magna Defender on Mirinoi, Mike returns and inherits the warrior's powers to fight at the Rangers' side.
	Scorpius, meanwhile, is joined by the treacherous mastermind Deviot, who soon orchestrates Scorpius's destruction at the hands of the Rangers. Scorpius's daughter Trakeena inherits his powers and seeks revenge on the Rangers.
	Aided by the Space Rangers against the resurrected Psycho Rangers, the Galaxy Rangers lose a member when Kendrix appears to sacrifice her life to save her fellow Pink Ranger Cassie. Although the Space Rangers return to Earth, former villainess Karone recovers the lost pink Quasar Saber and becomes Kendrix's surrogate.
	Soon, Deviot imprisons the colony in the Lost Galaxy, where the Rangers must battle the forces of Captain Mutiny. The colony is ultimately freed, due in part to the sacrifice of Mike's powers.
	Its engines nearly crippled, Terra Venture aims for a nearby world but is demolished by the mad attacks of Trakeena. The colonists escape to the planet below, and the Rangers apparently destroy Trakeena's superpowered form. Maya discovers their new home is actually Mirinoi, and the Quasar Sabers revive the planet and Kendrix as well.
On Earth, a horde of demons is unleashed from an ancient tomb. Led by Diabolico, the demons attack Mariner Bay, a city built on the ruins of their ancient palace after the destruction of the evil Queen Bansheera. Captain Mitchell, head of the secret organization known as Lightspeed, selects five teens to defend the city as Lightspeed Rangers.
After numerous defeats at the hands of the Rangers, Diabolico unleashes Mitchell's long-lost son Ryan, who steals an experimental Morpher to become the Titanium Ranger. Ryan ultimately joins the Rangers and triumphs over Diabolico's three angel-warriors, as well as a cursed tattoo branded on him by the demon leader. Diabolico soon falls and is replaced by Bansheera's son, Olympius.
The demons soon attempt to resurrect Bansheera, a plot only partially foiled by the Rangers, and Ryan departs to learn the secrets of banishing the demon forces. When Olympius doublecrosses his fellow generals, they strike back by resurrecting Diabolico. As the generals vie for power, Olympius is defeated in battle with the Rangers.
Soon, Bansheera completes her transformation into her physical form, at the expense of her generals' lives. Last to fall, Olympius and Diabolico are destroyed by the Rangers' new Lifeforce Megazord. When the queen seeks to unleash all the demons from the hellish Shadow World, the Rangers escape the destruction of their Aquabase just in time to seal Bansheera inside the Shadow World.
	In the year 3000, a mutant leader known as Ransik defeats Red Ranger Alex and escapes to 2001 with a prison ship full of mutant criminals. He is pursued by four Time Force officers who recruit Alex's apparent ancestor Wes Collins to unlock their Morphers and allow them to become Time Force Rangers.
	Wes ultimately proves himself as Red Ranger, and together the Rangers fight Ransik's forces with the help of Zords sent from the future. History slowly changes as Wes's father Mr. Collins involves himself in the battle to save Silver Hills. Meanwhile, the Rangers are watched and aided by a mysterious Time Force commander in the future.
	As the Rangers contend with the Silver Guardians, a mercenary squad owned by Mr. Collins, Wes's embittered friend Eric steals a long-lost Morpher to become the Quantum Ranger and leader of the Silver Guardians. Eric slowly begins to cooperate with the Rangers, protecting the secret of their future origin from Mr. Collins.
	Some time later, Ransik's robot assistant Frax betrays him by destroying a serum which he needs to survive. When Mr. Collins' company Bio-Lab synthesizes the serum to cure the people of Silver Hills after a toxic mutant attack, Ransik raids the lab and gravely injures Mr. Collins.
	Frax, meanwhile, begins construction of a super-robot, Dragontron. The Rangers are joined by the mystery man from the future, revealed to be the hard-nosed Alex. Told of his father's imminent death, Wes returns his powers to Alex and takes the reigns of Bio-Lab. Wes, however, soon rejects his destiny and reclaims his powers to lead the Rangers to victory against Frax. Alex returns to the future after healing Mr. Collins and setting history on a new course.
	In time, Ransik exhausts his supply of mutant criminals. Frax, meanwhile, completes a final robot, Doomtron, whose energies threaten to destroy the city. Alex once again changes history by retrieving his four fellow Time Force officers from their imminent destruction, but they soon return to fight alongside Wes. In a final showdown with the Rangers, Ransik accidentally strikes his reformed daughter Nadira and immediately surrenders to the Rangers. The officers return to the future as Wes and Eric remain to lead the Silver Guardians.
In the city of Turtle Cove, orphan Cole Evans seeks to learn the fate of his explorer parents. When he is recruited by four Wild Force Rangers to fight the evil Orgs, he steps in as leader of the team. The Rangers, based on the sky island Animarium, are aided by giant animals known as Wildzords as they battle the forces of a reborn Master Org.
The Rangers obtain numerous Wildzords until Master Org's general Nayzor unleashes the wolf demon Zen-Aku. The Rangers ultimately break the spell on Zen-Aku, reverting him to his ancient human form, Merrick. Now the Lunar Wolf Ranger, Merrick fights alongside the Rangers but does not join them on the Animarium.
Soon, Master Org's suspicious servants Jindrax and Toxica reveal him to be the human Viktor Adler, and they ultimately escape and seek a means to defeat him. The Rangers, meanwhile, receive the help of the Deer and Falcon Wildzords. When Dr. Adler returns to Turtle Cove, Cole is faced with the realization that his parents were betrayed and killed by their former friend. Adler is ultimately killed by Org general Mandilok but is secretly reborn as a true Org.
As the Rangers battle Mandilok's forces, they are aided - and tested - by the lord of the Wildzords, Animus, who assumes the human form of a boy known as Kite. The Rangers soon contend with Onikage, a ninja general sent by Master Org. Toxica loses her life after being manipulated into capturing the Rangers' mentor, Princess Shayla, but she is revived by Jindrax, and together they help the Rangers free Shayla.
The Rangers soon discover, however, that Master Org has used Shayla's powers to summon an Org Heart which transforms him into a powerful new form. Master Org promptly destroys Animus and the Wildzords, but the combined spirits of all the Wildzords return to destroy the villain. Shayla returns to the sky on the Animarium, and the Rangers return to their civilian lives.
	Earth is soon threatened once again when the dark ninja Lothor returns from exile seeking the destruction of the planet's mystical ninja schools. Three unlikely students are chosen as Wind Rangers under the guidance of Cam and his sensei father, now transformed into a guinea pig.
	Lothor soon counters by unleashing his two Thunder Rangers, whom the Rangers ultimately learn have been manipulated by Lothor. Learning the truth of their parents' demise, Blake and Hunter leave Blue Bay Harbor but soon return on the Wind Rangers' side.
	When the Rangers' powers are stolen, Cam journeys into the past and retrieves his mother's Samurai Amulet, allowing him to become the Green Samurai Ranger and save the day. Together the six Rangers repeatedly thwart Lothor's attacks, despite his acquisition of new generals Motodrone, Vexacus, and Shimazu.
	Lothor's generals scheme against each other, culminating in their mutual destruction. Having masterminded his generals' downfall, Lothor uses their energies to cause the Abyss of Evil to overflow. Despite losing their powers, the Rangers succeed in imprisoning Lothor in the abyss.
Elsewhere, former Power Ranger Tommy Oliver begins teaching at Reefside High, where three of his students stumble upon his ancient Dino Gems. When the reptilian Mesogog attacks, they morph into Dino Rangers to save the city. Dr. Oliver soon joins their ranks as the Black Ranger.
Soon, the teens' friend Trent stumbles upon his enigmatic father's double life as Mesogog. Trent is transformed into the evil White Ranger, whose powers increasingly corrupt Trent, but he is ultimately saved with the help of his father's human form, Anton Mercer. In return, Trent swears to keep his father's identity from his fellow Rangers.
In time, Mesogog's general Zeltrax creates an evil duplicate White Ranger, a force which prompts Red Ranger's transformation into the Triassic Ranger using his teammates' energies. Zeltrax is apparently destroyed but later returns to plot against both the Rangers and Mesogog.
After Mesogog's double agent Elsa is revealed as Reefside High's Principal Randall, the Rangers soon learn the truth about Anton Mercer, and Trent is forced to prove his loyalty. Mesogog, meanwhile, separates from his human host, at which point the Rangers raid his island fortress and rescue Mercer. They then rescue Elsa from Zeltrax's clutches and exhaust their powers by destroying Mesogog.
	Fast forward to the year 2025... When intergalactic warlord Emperor Gruumm and his Troobian armadas seek to conquer Earth, now a haven for extraterrestrial immigrants, Space Patrol Delta dispatches A-Squad, an elite Ranger force. But when Gruumm ambushes A-Squad in another galaxy, Earth's only hope is B-Squad, the capable but quirky offspring of SPD's original roster.
	Several battles later, Gruumm's evil assistant Mora, a magical ten-year-old girl, tries to turn a young mutant boy named Sam against the Rangers, but the boy joins SPD's ranks. When Gruumm's general Benaag arrives, SPD's Commander Cruger, having survived Benaag's attack on his homeworld years ago, returns to combat as the powerful Shadow Ranger.
	Eventually, Gruumm's forces, including Morgana, the adult form of Mora, gain the upper hand over the Rangers, until the arrival of the Omega Ranger, an energy being from an alternate future ruled by the Troobians. The Rangers are stunned to learn that he is the future form of their young friend Sam, and Morgana is left with the task of plotting the seven Rangers' defeat.
