Time Traveling Information

Recently, I watched an anime called Steins;Gate. The series is about time travel and if you have yet to watch it, I highly advise you do so. Be warned, below are some spoilers.

In Steins;Gate, one form of time travel they use is not by physically sending the traveler, but using information. As a physical being such as a human cannot live in the intense conditions of a black hole, they send information, usually an e-mail. These e-mails that go back are named D-Mail. I find this to be a very interesting concept, and I am curious if this has ever been considered. If anyone would like to give their opinion on this concept, I feel that a discussion on this would be every entertaining and intriguing.
 
I think it would easier to send information back in time rather than a human being.Because the human being would need a vehicle and the information does not.
 
Even without a vehicle, the difficulty would still be extremely high.

The anime revolves around sending D-Mails back in time by the use of a miniature black-hole.
However a black-hole is a singularity, and electromagnetic radiation is affected by gravity.

1. I don't think it'd matter if you send a person or a D-Mail, since the gravitational forces would still be to strong to let anything out again.
2. If the matter (Or in this case, electromagnetic radiation) was thrown out by a white-hole, it would be accelerated without any external forces at work. That of course would create a perpetuum mobile, and I'm not really fond of that idea.

Anyway, I guess they work their way past those problems later in the series, I'm only at episode 3.

Would you mind please explaining to me what a perpetuum mobile is?
 
Perpetuum mobile means perpetual motion.I believe i could build one with water,trapped air and a hole for air.I research free energy and seen some astounding claims.

It is a perpetual motion machine. It moves forever without an external energy source.

Our slightly flawed AI got it wrong. Perpetual motion is an acceleration without an external force acting on the body. If we set a body in motion in a vacuum, for example, it will move forever in a uniform motion of translation. An inertial motion. Should it accelerate without an external force acting on it then we should be surprised. Something about "arrows" is involved here.

Actually the term should be an unequal force. If it's a U-238 atom and it undergoes an alpha decay there will be an acceleration (for both the newly created He-4 and Th-234). That might be termed an "internal" force acting on the body(s). The strong force, which was responsible for the decay, came from within the uranium nucleus.

Maybe we don't have to enter a black hole to time travel
Maybe time travel has nothing to do with black holes

We would not survive entry into a black hole. I've read about two theories. One involves the black hole bringing time periods closer together so you can ride the wave around it. The other is Dr. Ronald Mallet's theory. Two singularities with parallel poles are lined up and create a field. (Something to that effect anyway).

I thought both still involved getting into the actual singularity?

I'm going to look up those theories. They seem interesting.

Not by what I've read, but I'm not a physicst or scientist of any sort. I just run my mouth about my theories a lot. :)

Often times it can take one who does not know much of a certain topic to unravel more of its mysteries. Even if they might not be right, it is also possible that they could open the eyes of other scientists on the possibilities. Please, keep discussing your theories, it helps, I hope.

I leave most of my theories on my website. Nobody seems to become upset that way.
