If the universe starts shrinking, would the time go backwards or would it just be the same?
If one day the Universe starts to retract, would the time flow backwards?
Could we ever reach the non-observable universe using time dilation in the same way we could reach Andromeda? Will mankind ever travel back and forth through time? What if we are actually moving back in time? Can one differentiate a backward flow of time from forward flow? Is the universe expanding day by day? Is it theoretically possible to reverse time? If time travel was possible how would the universe remember the moment? Would the universe be like a computer? Would time travel be like hacking? Could time be flowing as a wave? Is time traval possible in future? Is time expanding with the universe? If time travel is possible, would our universe be in the first and original timeline and no one from the other timelines would be able to interfere? Does time flow? Can we turn back time? Is it true that we could travel back to the past if we surpassed the speed of light? If time traveling towards the future is possible, why not towards the past? Is it possible to travel back or forward in time? Is it physically possible to travel back in time? Can we reverse time? If time is a continuum how is reincarnation possible? What if time was passing a bit faster here on Earth? How can time begin at the Big Bang? Can we travel back in time? If not then why? If we all together stopped every single clock/watch on earth for a while. Would we lose track of time? Is it possible to reverse time? Theoretically time travel into the future is possible, but what about time travel into the past? What would the world be like without the concept of time? How do we estimate the time since the big bang? Did the universe have a starting point, or was it always there? How do we measure time since the Big Bang? Is time travel possible through cosmic strings? Time (physics): If all the clocks in the world stopped working for a few days, would we be able to regain the exact time in seconds, minutes and hours?
