| Super massive Black Hole |
First Way of Time Travel
Stephen
W. Hawking refers to Black Hole as a natural time machine, though not directly
referring to time travel. The black hole is so dense that it dramatically
interferes with time. It can slow down time from anything in the universe.
If a
spacecraft rotates very close to the black hole, it will gain about 5 minutes
in orbit every 5 minutes. That means it will take less than 5 minutes. Thus, as
long as it rotates periodically, the spacecraft will receive half its time. As
a result, members of the spacecraft will travel on time. That is, if they came
back to Earth after four years of black hole, everyone in the world would be
ten years older than that. Just as it was shown, in the Interstellar movie by
Cheristopher Nolan. But with the time shown here, it is not possible to achieve
this much time in practice.
In this
regard, Stephen W. Hawkings points out, "Even if it cannot be taken back
too much, it will not be possible to return too much." But the problem
with this is the black hole's visibility. Because, if light cannot be reflected
from an object, we naturally cannot see it. Since no light can be reflected
back from the black hole, we find it beyond our power of vision. Moreover, the
super-gravity of the black hole in the center of the ball will never be safe,
preventing the ball or getting close to this range. Although some of our
theories, until now, say that time inside the black hole is running past. That
is, the clockwise rotates upside down. The idea of time travel with Blackhole
is why Blackhall occupies such a place of interest.
