Ok so for starters, i am not nearly as smart as the least-smart person on here, but I have been reading a lot about all sorts of stuff.
We now know that the ability to "send" someone to the future is possible, by having that person travel to a black hole, orbit it for some time and return.
the biggest problem is that it is impossible in our current state for a human to travel the nearest black hole which is super far away, (unless the government or someone is holding out on some serious cryogenic technology on us).
Everywhere that I read has said this 'time travel' is possible with a black hole, however my thought is why hasn't anyone mentioned the next best thing that we could currently get to.... the sun?
We know that just by being in space, someone would already experience time slower than on earth, just the trip alone to the sun and back would allow for some significant time difference.
So, if someone were on a heavily leaded ship, with a vacuum layer or two, a highly efficient reflective side, and an awesome radiator on the dark side, wouldnt they be able to orbit close enough to the sun to experience time dilation in a relatively significant amount where upon a return of say 10 years wouldn't the Earth be significantly in the future?
obviously the closer the orbit possible the more time dilation correct?
also not considering a food source for that duration... would have to figure that out.
now I had read somewhere that if one were to orbit the nearest black hole for 15 years they would return to Earth and 50-75 years would have passed, (roughly calculated im assuming), so in theory wouldn't doing the same around the sun result in a time dilation but maybe not as intense... but even another 5-10-20 years would be something incredible.
so if this is dumb and everyone on here is like "wow youre a dummy" I apologize, but maybe let me know why that wouldn't work.
