TIME WARPING |
|
Black holes suck in objects but -- according to Einstein's
general theory of relativity that time reversal is possible -- objects that travel through
black holes could theoretically be spewed out of other holes. Such holes are called white
holes. The tunnels that connect black and white holes are known as wormholes.
The space-time tunnels of another world
Black holes are the final stage of a star's development. But in extraordinary times, such
as the start of the Universe, wormholes could be created. If the changing nature of space
and time is considered, it's better to think that wormholes appear and disappear. By
thinking closely about wormholes, it's possible to understand that there is a different
world to the one we live on. If we consider both these worlds as being parallel, wormholes
are like a space-time tunnel that joins our world to the other.
Wormholes present time travel opportunities
Kip Sone, a relative theorist, devised a theory where wormholes could act as time
machines. He believed that, according to the principles of quantum mechanics, if a space
ship was strong enough to travel at something near light speed through a wormhole, time
would travel backwards. By following the principles of the special theory of relativity
that say time moves slower for objects traveling at the speed of light, it would be
possible to travel in time.
Stephen Hawking has dismissed the possibility of creating time machines
There are a number of factors working against the theory of creating a time machine and
it's better at this stage to consider its construction impossible. Stephen Hawking has
often said that if the effects of quantum mechanics are considered, the construction of a
time machine is not possible in the real world. |
