How big would a real Death Star be?

120 to 160 kilometers
In short, don’t count on it happening anytime soon: The actual size of the Death Star, according to their estimations, is close to 120 to 160 kilometers in diameter, and would cost the equivalent of 18 quadrillion dollars to build.

Why did they build the Death Star?

The Death Star was designed to allow Emperor Palpatine to more directly control the Galactic Empire through fear. One Death Star was completely built by the Empire, with a second and third one never reaching full completion, as well as a prototype being in existence.

Is the Death Star laser realistic?

To lend a veneer of real physics governing the galaxy far far away, here’s a “scientifically accurate” take on the Death Star’s superlaser. Although while this Death Star superlaser’s a lot more realistic than the original, it’s not nearly as visually striking. In a few different senses.

Is it possible to build a Death Star?

Although generating enough metal to build a Death Star would be “bonkers,” technically speaking, it would be possible, Peck said. But there would need to be a huge space industry infrastructure to support it, including the ability to launch many more rockets than we can today, and asteroid mining.

What would happen if we sent the Death Star to space?

Rocket launches to send all that metal and other building materials to space would “pollute the atmosphere to the point that anyone left who could use the Death Star would have to live on it — Earth would be uninhabitable,” Pyle said.

Could ‘hypermatter’ be used to power the Death Star?

“Of course, in ‘Star Wars,’ they used ‘hypermatter’ to power the Death Star,” he added, “so who knows what might be possible with this new and improved source of destructive power?” The Death Star uses a convergence of laser beams to destroy planets. The real-world feasibility of such a device is suspect.

Could ‘Star Wars’ Death Star have a laser?

Muirhead added that the laser on the Death Star is a technical problem, as it would likely require an output many times that of our sun, “an extraordinary amount of energy,” he said. Still, he can’t wait to see the new “Star Wars” movie.
