Time travel into the future is totally possible
Time travel into the future is totally possible not).
And what's even cooler is that you can skip forward in time if you feel like it.
Well, let me be clear, you need to do a little bit of engineering first.
We know through the physics of Einstein's special theory of relativity that you can trade motion in space for motion in time. If you're standing perfectly still, you're moving through the dimension of time at a particular speed (the speed of light, for those of you who are curious). As soon as you start moving through space, however, you slow down your rate of moving through time.
In other words, the faster you move in space, the slower you move in time.
This means that moving objects, like a clock on a rocket, run a little bit slow. One second for someone in a moving spaceship lasts a little bit longer than a second for someone staying still.
The trick is that in order for this to have any sort of noticeable impact, you have to get close to the speed of light, which is really hard to do—to give you some perspective, astronauts that orbit the Earth at tens of thousands of miles per hour are off by only a microsecond or so from our clocks on the ground.
Our fastest human spacecraft don't even crack a tenth of a percent of the speed of light. But if you could somehow spend a good amount of time hugging close to that ultimate speed limit in the universe, the slower your clock will run. You will travel through time into the future. Nothing will feel different for you, but after a couple of years' journey you would return to the Earth to find our clocks advanced by thousands or even tens of thousands of years, depending on how fast you go.
So the future is yours, and you get to choose how quickly you reach it.
