keep in mind i am just an average highschooler who likes to read, but i was just wondering about something that i couldnt find in books or the internet. i know that the speed of light is 186,390 miles per second, so in turn you would have to travel that many miles to "go" back in time one second. but wouldnt that only be the case if you were on a level plane of time? i guess my real question is that if you were standing on a black hole, would that one second be much much closer due to gravity bending time? i hope that made sense enough for you to clarify for me. thx.
