Are wormholes theoretically possible?
Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen. Theoretically, a wormhole might connect extremely long distances such as a billion light years, or short distances such as a few meters, or different points in time, or even different universes.
Could we travel through a wormhole?
Some wormholes may be “traversable”, meaning humans may be able to travel through them. For that though, they would need to be sufficiently large and kept open against the force of gravity, which tries to close them. To push spacetime outward in this way would require huge amounts of “negative energy”.
What is space travel and why is it important?
Why is space travel important? Space exploration is the future. It satisfies the human urge to explore and to travel, and in the years and decades to come it could even provide our species with new places to call home – especially relevant now, as Earth becomes increasingly crowded.
What is the best way to travel through space?
Also known as wormholes, Einstein-Rosen bridges are perhaps the most commonly known means of interstellar travel — and the most likely to actually exist. Albert Einstein’s general theory of relativity predicted wormholes, although we haven’t seen one yet.
Does space travel make you age prematurely?
Some researchers are beginning to believe that space travel could have the opposite effect. It could make you prematurely old. Above: Albert Einstein’s theory of Special Relativity says that time slows down for fast-moving space travelers, effectively keeping them young.
Can space travel technology lead to down-to-Earth applications?
Pushing forward the frontiers of science is the stated goal of many space missions. But even the development of space travel technology itself can lead to unintended yet beneficial ‘spin-off’ technologies with some very down-to-earth applications.
