Where does space end?

It extends about 20 miles (32 kilometers) above the Earth. Floating around the atmosphere is a mixture of molecules – tiny bits of air so small you take in billions of them every time you breathe.

Has a time machine been invented?

In fact, a time machine has already been built. Scientists, however, are still working on how to make it as efficient as possible, like in the Back to the Future movies. What is a wormhole NASA? '' Wormholes are spacetimes with nontrivial topology in which a kind of tunnel exists connecting distant parts in the universe. These wormholes may not only serve as shortcuts in space but also for timetravel.

Can I make a time machine?

However, in order to make it work, the concept would require vast amounts of power and a way of shrinking everything to a microscopic scale. But once we have a time machine, using it successfully will require a detailed understanding of time itself. Who discovered black hole? Albert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. The term "black hole" was coined many years later in 1967 by American astronomer John Wheeler.

What is Stephen Hawking's black hole theory?

That's where Hawking came in. In 1971, he suggested that black holes formed in the chaotic environment of the earliest moments of the Big Bang. There, pockets of matter could spontaneously reach the densities needed to make black holes, flooding the cosmos with them well before the first stars twinkled. What is on the other side of a Blackhole? The discovery of light from the other side of a black hole was predicted by Einstein's theory of general relativity. But it has never actually happened before, and the discovery marks the first time that light has ever been directly observed coming from behind a black hole.

What could destroy a black hole?

There is nothing we could throw at a black hole that would do the least bit of damage to it even. Is NASA building a warp drive? According to Popular Mechanics, the NASA warp drive will expend a massive amount of energy that will "warp" (contract and twist) space time behind the spacecraft, which will create a space time "bubble." This bubble, which will be created around the ship and curved behind it, will theoretically reduce the distance that

Is NASA working on a warp drive?

DARPA and NASA Scientists Accidentally Create Warp Bubble for Interstellar Travel. A Defense Advanced Research Projects Agency-funded research project at NASA's Johnson Space Center may have accidentally discovered how to build a warp drive engine. The scientists published their findings in July.
