How is evolution envolved.

Time travel can change history, and can also change the evolution, so what we are right now, we might not be if someone goes into the past, and

Speed of Light.

Speed of light is the reason why we can time travel, it travels at 299 792 458 m/s but it is nearly impossible for us to reach the speed of light, we need infinite amount of energy to reach the speed. The theory of relativity says that the faster you go, the slower the time gets, for you, but for the

people of Earth, time is normal, so, you

are aging slower than others, and traveling into the future

Is Time Travel Possible

We can time travel into the future, but you can't go into the past that easily. We can travel into the future by traveling at the speed of light, but in order to travel into the past, we have to travel faster than light speed, and that is, impossible to do right now, but it might be possible one day.

Black/Worm holes

Black holes are created when a star dies, but it's gravitation remains there, and it creates a big, deep hole in the space fabric. Wormholes are a shortcut in space time, with two ends, one entrance, the other exit to the other universe, no body has ever seen them, they are theoriatical, but if we ever go near a black hole, time will slow down for us because of high gravitation, therefore we will go into the future, because time is normal in Earth.

Problems with time travel.

There are many problems with time travel, there are paradoxes that you can get stuck in,

The Grandfather Paradoxes,

Please put the https before the link to watch the video.

What would happen if you step on a bug, and that acttually started your generation, you would not be alive.

What if you see yourself in the past, and you bring him into the future, the every time you can go back and get yourself, you can be 1, 2,3 100 people like you from the past.

What would happen if you used the information from the future, and use it in the past?

you see, we can create endless paradoxes, and we can stuck in it if we time travel.

Conclusion

Our conclusion is that you can time travel, but you need to reach the speed of light, to time travel into the past you need go faster than the speed of light, or use cosmic strings, that are defects in time-space fabric. But you can't travel that fast yet, the only way to do is to go in a place with higher gravitation, because gravity can slow down time, Example: Near a black hole, or even places on Earth, like standing near a place with higher gravitation like pyramids, can have an affect on your time, because of gravity.

Time travel is more dangerous, than beneficial, because even one minor mistake, can lead to

consequences in the future, and in the present too, like if you step on a bug, that was once your ancestor, it could lead to your death, but then who went back to kill the ancestor, paradox. But what if you killed Adam's one son, then you would probably kill more than half the world population, and then you have it's consequences, time travel is just not safe.
