What are possible problems with traveling faster than light?

So-called “warp drives” have been proposed before, but often rely on theoretical systems that break the laws of physics. That’s because according to Einstein’s general theory of relativity, it’s physically impossible for anything to travel faster than the speed of light.

Can you achieve speeds faster than light?

No. The universal speed limit, which we commonly call the speed of light, is fundamental to the way the universe works. Therefore, this tells us that nothing can ever go faster than the speed of light, for the simple reason that space and time do not actually exist beyond this point.

Is a black hole faster-than-light?

Using NASA’s Chandra X-ray Observatory, astronomers have seen that the famous giant black hole in Messier 87 is propelling particles at speeds greater than 99\% of the speed of light.

Will we ever achieve warp speed?

Seriously. Humans are one step closer to traveling at faster-than-light speeds. A new paper proposes a fully physically realized model for warp drive.

Why can’t anything travel faster than the speed of light?

As an object approaches the speed of light, its mass rises precipitously. If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.

Could a tachyon ever slow down to light speed?

If a tachyon did exist, it would always move faster than the speed of light. Using the same reasoning as in the case of slower-than-light particles, you can prove that it would take an infinite amount of energy to slow a tachyon down to light speed.

Can we push the speed of light beyond known boundaries?

Researchers say it is the most convincing demonstration yet that the speed of light — supposedly an ironclad rule of nature — can be pushed beyond known boundaries, at least under certain laboratory circumstances. “This effect cannot be used to send information back in time,” said Lijun Wang, a researcher with the private NEC Institute.

Is there a way to break the speed of light?

The Confirmed Exception. There is one way around the speed of light restriction. This restriction only applies to objects that are moving through spacetime, but it’s possible for spacetime itself to expand at a rate such that objects within it are separating faster than the speed of light.
