ok i understand how we would be able to travel into the future but i have some questions... so if some one traveled at the speed of light and came back in an hour, they would be millions of years into the future right? well does that mean that we'd all die in an hour because nobody can live to be that old?

NO! im talking about if i was on earth and someone else traveling the speed of light

You clearly do not understand time travel.
If someone traveled at the speed of light for an hour, the passage of time to them relative to people on Earth would seem less. For example, if this person had a twin then the traveler would seem younger.
The passage of time relative to yourself always remains the same. An hour is an hour, whether you are traveling at light speed or remaining stationary. If you live to be 65, you will experience 65 years regardless of how much of that time was spent traveling at light speed.

The time traveler would have only an hour of his life pass. Those on the earth would life out their life spans. The time traveler would return to an earth millions of years into the future, and all life present when he left would be long gone.

no because we wouldnt be millions of years old, actually we would only be an hour older. even though we traveled millions of years into the future
this is because of einsteins theory of relativity. it pretty much says that if a space ship or if anything traveled really fast, like at the speed of light. the space ship or thing travelling that speed will get much much smaller and shrink. not only will it shrink but the time inside the rocket will slow down. this is kind of hard to wrap your brain around but maybe this will help
imaging your in a rocket ship, thats not moving at all. and you measured the height of the rocket from floor to ceiling using a ruler. its ten feet tall. then the rocket all of a sudden took off at the speed of light. at this point the rocket will shrink to a little tiny rocket. but intristingly you will shrink the same amount, so will your eyes, and your brain and your ruler. so when you use the ruler to measure the rockets height it will still be ten feet tall because the ruler will be samller too, you wont even notice this because your eyes will be smaller and your body will be smaller so it will look the same size. i brought this up because the same thing happens with time. because when you travel faster, time will slow down, but so will your watches, so one second will always be one second, even though at that time seconds last for hours, you wont notice it because you will slow down too and everything will seem as if its going at normal speeds
i brought this up because its very important to know that when talking about traveling the speed of light. so if we traveled millions of years into the future, we will actually only be expiriencing an hour of time because time will slow down so much that only 1 hour will pass by when we will actually be moving for millions of years. we wont age millions of years though because our bodys mechanics will slow down so it will only age an hour. get it?
so if one person was on earth and one person was in a rocket traveling time, and the person in the rocket came back, they would have both only aged for an hour
if you stayed in the future, the person on earth would be a million years old (dead) and you will be an hour older.
i spend alot of time on this answer so please at least give me ten points
now give me the best answer lol

Because you travel the speed of light, your body wouldn't even age because it only took and hour to get to a million years later. Your body only thinks an hour has passed.

It is impossible to tell but I would say it is very impossible to consider traveling at the speed of light, giving the variable of speed takes an infinite amount of energy. That energy has no minimum or maximum amount of energy used, meaning that time would have to run parallel to eternity. In order to travel at speed of light time would have no meaning. In effect we cannot exist at the speed of light because without time, we have no distance or dimension. Therefore it is out of the question with any tangible reasoning. No life no death

No. When we travel into the future, it is time around us that moves slower, so while age for an hour, the universe ages by millions of years. We wouldn't be dead because it only takes us one hour to travel millions of years.

An hour would pass for the traveler. He/she would have only aged an hour during the trip. To the rest of us...a million years would pass and we would never see the traveler again after they departed.

time is a relative question, it is theorized that by traveling at the speed of light for an hour you would experience it as an hour but to someone not traveling at the speed of light it would take melnia

You cant tavel at the speed or light. Your mass would be infinity requiring a infinit amount of energy to move you. If you move near light speed you slow down and the rest around you speeds up.

One hour of the traveler's time, or one hour of our time?
Because the time would not flow at all for the traveler, so in that instance, one hour would be an infinite amount of time for us.
One hour of our time would feel like zero second for the traveler, but still be one hour for us.
