Back where?
In an Einsteinian four-dimensional universe you'll always exist in a very literal sense. Just, you know, "back there".
I think that there are lots of consolations in the scientific worldview that make up for our mortality, though. The elements that form everything from my body to the air I breathe exploded out of the hearts of ancient stars. To live at all is miracle enough.
Well, if time's a fourth dimension, you're just further back along in that particular direction in the overall shape of the universe.
That seems a bit presumptuous that our sentience actually has significance on some level and that it's not just an evolutionary coincidence.Taking the purely pragmatic route of reproduction misses something for me, and it forgets our status as sentient beings rather than reproducing automatons.
I remember hearing about this on a Science Channel special on Stephen Hawking in which he "prooved" that information could in fact be lost inside a black hole. I don't remember whether this was the theory that turned out to be his big blunder or not, but I think it was, and then he offered some alternative explanation that there could be multiple parallel universes and that only the histories of those universes in which information wasn't lost would actually matter. However, I'm no Einstein and I'm no Hawking so I don't find myself qualified to pick a side in this argument.In an Einsteinian four-dimensional universe you'll always exist in a very literal sense. Just, you know, "back there". Information theory says that there is indeed a record of your being, and it can't be destroyed either, not even by a black hole! So we're all ineradicable parts of the grand structure of the universe.
I think this is a point that too few people seem to realize. Many overlook this and spend their time fretting eventual death rather than admitting or even understanding how infinitely lucky they are to have ever been born at all.I think that there are lots of consolations in the scientific worldview that make up for our mortality, though.

Time is altered by gravity. Falling into a black hole, you'd see two seconds on your watch tick off as hundreds of thousands of years pass around you.
Time is relative. If you flew to our nearest neighboring star at 99% the speed of light, and then flew back to Earth, you'd have been gone for a thousand years even though it only felt like ten for you. Likewise, faster-than-light travel would send you back in time along that fourth dimension, where everything is always still happening.
What is practical has very little to do with the way things are on very large and very small levels.
* By the same physics, both scenarios are physically impossible.
* Hawking's himself completely reworked his black hole model in recent years.
* Your argument concerning black holes is thus, still subject to unfounded mathematical and physical theory.
* Most importantly, relativism does not imply time travel, only time variance in a single moment.
* Postulations regarding time travel create many unanswerable paradoxes.
* No one has yet proven time travel possible even on a quantum scale.
right...in that case...the electrical discharges dissipate. It's gone. Your mind dies...
as for the information lost, I guess it would still be in your brain in the neural pathways. That stuff only gets lost when the maggots eat your brain.
