I have gone back in time and forward in time, I was at Exit 369 on the western edge of the Texas Panhandle and the eastern edge of New Mexico, step back in time and then stepped forward in time. Not really going back and forth in time, just time zones.
(7:34) Another option I like to think of, is that time is like a tangled retractile telephone cord: it _always_ moves forward. Even if you could go back in time and stop your grandfather and grandmother from ever meeting, you don't pop out of existence. The interference you've created, is part of your limited lifespan, still moving forward.
Time paradox didn’t make sense to me back then but it’s possible with quantum mechanics but that issue has infinite possibilities so getting back to the same time is also improbable
Impossible
Documentary like this strengthens my belief in God Almighty because He is present all the time throughout all the universe and beyond.
We can't not go to much back in time COZ MORE YOU GO BACK SLOW DOWN YOUR HART 💗
Who's watching in 3077?
From the perspective of an object traveling at the speed of light, there is no experience of time; the journey from its source to its destination is instantaneous.
Dragon Ball already explained this, when Trunks travelled into the past, he created a new timeline 👁👄👁
I don’t think we ever achieve time travel because if we did, we would see a bunch of people coming back now
Parallel Universe! That reminds me of on old network television show "Sliders!"
That was a great blast from the past. I think I enjoyed it more this time.
Thought is the only thing faster than light. Your thoughts create your future ✨️
I want to travel back in Time
Great show
Time is like quicksand. The more you struggle with it, the faster you fall into inevitability...
Such a 2000's tv intro. Take me back. 😅
@ 18:15 "NOW THAT WHOLE THEORY IS ABSOLUTELY GENIUS MATERIAL"...!!!🧐🤔🤔. THANK YOU FOR THAT INFORMATION GENTLEMAN, BRILLIANT...😮😮
Everytime you view a photo, listen to music or watch a movie you are travelling through time, truly astounding how much such miracles of Human invention are taken for granted.
The closest we could come to travel into the passed wound be to somehow travel a gazillion times the speed of light, stop, and with some incredible telescope, we could image the earth's surface when light light reaches us a see how the pyramids were built
