The swamps of Dathomir were home to the Nightsisters, also known as the Dathomir witches, Force-wielders who used the power of magick fueled by the planet’s own dark energies. Some have become reality (holograms, heads-up displays, robotic arms). Others are in sight (landing people on other planets, robots in every home). Some may never be (manmade stars and, sadly, real lightsabers). As the Force awakens, 38 years after it was born, Georgia Tech faculty members discuss the science, and science fiction, of Star Wars. Luke Skywalker is a fictional character and the main protagonist of the original film trilogy of the Star Wars franchise created by George Lucas.Portrayed by Mark Hamill, Luke first appeared in Star Wars (1977), and he returned in The Empire Strikes Back (1980) and Return of the Jedi (1983). Surrounded by a bright nebula, the Force planet is a barren place, featuring only luminescent geysers that shoot energy from deep within the world. Several islands hover above the surface, each teeming with plant life and strong with the Force.

'This is Master Obi-Wan Kenobi. I regret to report that both the Jedi and the Republic have fallen, with the dark shadow of the Empire rising to take their place. This message is a warning and a reminder for any surviving Jedi: Trust in the force. Do not return to the Temple. That time has passed, and our future is uncertain.'
–Obi-Wan Kenobi

Trust in the Force is the fifth Force Pack in the Alliances cycle for Star Wars™: The Card Game.

While the mighty mechanical feet of the Galactic Empire's AT-ATs and AT-STs trample across the galaxy, the defenders of freedom hide themselves on desert planets and in the icy wastes, biding their time until they can mount a critical counterattack. The Jedi haven fallen. Alderaan has been destroyed. But these Scouts, Leaders, Troopers, and Force Users still have hope for a brighter future. They still trust that if they can rally new recruits—and spur new worlds to action—they can still win the war.

With its sixty new cards (including two copies each of five new objective sets), Trust in the Force pushes the Alliances cycle closer to its climactic conclusion. Even as it continues to develop the cycle's support for decks that feature two or more affiliations, Trust in the Force follows the march of General Veers and his Walkers across the frozen surface of Hoth. It lends support to those massive war machines with a new Scum objective set that protects and enhances your Vehicles. And it peers into the hidden corners of Hoth and Tatooine, where Jawas, Rebel Troopers, and Jedi Masters all work in secret to rally new forces against Imperial tyranny.

This is not a standalone game experience. Requires a copy of the Star Wars™: The Card Game Core Set to play.

Destroying an entire planet all at once? It happens in 'Star Wars,' but could it happen in real life? Peopleimages.com/Getty Images

In 'Star Wars: The Force Awakens,' an evil military junta called the First Order has risen from the ruins of the Galactic Empire, and is waging war against with a particularly frightening new weapon. Starkiller Base, as it's called, is an icy planet that's essentially been converted into a giant ray gun, capable of obliterating an entire distant solar system with a single shot.

The bad guys upped their game considerably since the first 'Star Wars' movie, in which the Empire's ultimate weapon was the Death Star, a moon-sized space station with the ability to destroy a planet.

As the official Star Wars website explains, Starkiller somehow harvests energy from the star it orbits, and then contains it within magnetic fields inside the base's planetary core. That energy is then harnessed and converted into an 'ultra-powerful beam' that can blast through hyperspace — apparently a so-called wormhole in the time-space continuum in which incredible distances can be covered at speeds faster than light.

When the beam comes out at the other end of hyperspace, those in its path are doomed. The Starkiller's beam is 'able to sterilize the worlds of a distant star system with a single shot,' we're told.

The Nitty-Gritty Starkiller Mechanics

As often happens in science fiction, the details of how Starkiller would actually work are left to the audience's imagination. And if you've suspended disbelief and immersed yourself in the 'Star Wars' fictional universe, the idea of a weapon so immensely powerful probably doesn't seem any harder to buy than lightsabers, talking robots with human-like personalities, and The Force itself. In the actual universe that we live in, though, is a solar system-killing weapon even remotely conceivable? A k de environmental chemistry pdf. And if so, how would someone build it?

University of Glasgow professor Martin A. Hendry, head of the university's School of Physics and Astronomy and an occasional lecturer on the physics of 'Star Wars,' says that that though the Starkiller is fantasy, it has at least a little reality mixed in.

'The Sun's magnetic field is very important in funneling hot plasma, an ionized gas, close to its surface,' says Hendry in an email. 'We see these huge ribbons of hot gas as prominences, and they can be the cause of violent eruptions known as solar flares that send large amounts of hot gas across the solar system — producing displays of northern lights when the plasma hits our atmosphere.'

A really powerful flare, he says, could create an electromagnetic pulse with extremely destructive effects. 'It basically would send our technology back to the Stone Age,' says Hendry, but it wouldn't be enough to wipe out the planet, the way that Starkiller supposedly can.

Hendry says the idea of using magnetic fields to contain and direct beams of plasma — which is pretty close to what Starkiller supposedly does — is based on perfectly sound physics.

'Where it jumps the shark is the way that the plasma is being directed from the star to the planet with the Starkiller base through apparently empty space,' he says. 'How does the Starkiller base generate a sufficiently intense magnetic field to re-direct so much of the star's plasma towards it? I thought the effects during that sequence looked great, but the physics wasn't very sound I'm afraid.'

While the idea of stealing energy from a star to power a weapon seems like the way to go, 'it's just not clear how you do it,' says Hendry.

Actual Star Death

When stars are wiped out in the real universe, they often do it to themselves, by blowing up into supernovas when they run out of fuel. Another way that a star can be destroyed is if it collides with a black hole, whose intense gravity creates forces that literally can tear a star apart if it comes too close, according to an article on NASA's website.

When that happens, the event is called a tidal disruption, and most of the resulting debris is sucked toward the black hole by its gravitational force. As that happens, the debris is heated to millions of degrees in temperature, and generates an enormous amount of X-ray radiation until the debris falls beyond the black hole's event horizon, a point from which no light can escape.

Astronomers actually have used NASA's Chandra X-Ray Observatory, the European Space Agency's XMM-Newton and the Swift Gamma Ray Burst Explorer in concert to observe a black hole's dest
