Is it true that if we will travel faster than the speed of light, we can go toour past?
Is it true that we could travel back to the past if we surpassed the speed of light?
When will we be able to travel at the speed of light? Can't light reach us quicker if it was emitted by something coming towards us at near the speed of light? Could we ever reach the non-observable universe using time dilation in the same way we could reach Andromeda? Will we age when we travel at the speed of light? If (theoretically) I reach the speed of light, does time apparently stop? If I surpass the speed of light, does time appear to go backwards? Why do we assume that travelling faster than the speed of light necessitates time travel? What happen if we moving with the speed of light? If one day the Universe starts to retract, would the time flow backwards? What if time was passing a bit faster here on Earth? Will a body traveling at the speed of light experience aging that is relative to the time-space of the destination or the source? Theoretically time travel into the future is possible, but what about time travel into the past? Will the speed of light ever change? Is it possible for human to survive if they travel at the speed of light? If I was going the speed of light and travelled 10 light years, would that be 10 years to someone on earth or 10 years to me? Does time travel at the speed of light? Can you travel at the speed of light? What can travel faster than the speed of light? Couldn't we avoid time dilation by a reinterpretation of special relativity? Will we ever have the technology to time travel? What is the furthest into the past that astronomers can currently see? Will we be able to see even further as technology advances? Is time travel possible after the discovery of gravitational waves? Is time travel possible through cosmic strings? If photons don't travel through time, why does it still take time for them to reach our eyes? If an object could travel at the speed of light, what would happen to it? If humanity was transported to an unknown galaxy, would there be a way to keep track of time the same as we do here? How? If we all together stopped every single clock/watch on earth for a while. Would we lose track of time? Does light travel through space forever? If we could travel at the speed of light and in time? How can we make sure that none of our body atoms get left behind? If I could travel at the speed of light, what would I see? Why is there no time when traveling at the speed of light?
