Is time travel possible?Watch
I'm doing my epq and thinking of focusing on analysing relativity. Anyone able to offer any opinions on this or input of their own answer to the very open question.
There is an excellent wiki books book on the topic, if you first learn about matrices and linear algebra in maths
other than that I'd recommend reading why does E=mc^2 by Brian Cox and Jeff Forshaw
Theoreticallly, Time Travel is possible... If you were build a Maglev like train that had no resistence at all then yes you would be able to bend the laws of Physics and time travel but due to the thickness of our atmosphere we wouldn't reach a high enough speed prior to reaching lateral terminal velocity however if the financial infrastructure and technological infrastructure for that matter were there in maybe a Developed Country we would be able to fly to our nearest black hole and go into its gravitational pull which would then bend the laws of Physics and time travel depending whether you went Anti - Clockwise or Clockwise will depend whether you go back in time or not. Then we come to the dimensional dilemma of how do you land a futuristic NASA invention in the 1850s without the English spilling their tea... That would be all together another post.
Travelling into the past would include going faster than the speed of light and a lot of other complicated stuff which is deemed impossible.
Well that`s just not true- staple some water to a tree without a container then
It's just the notion that what might seem impossible now will most likely become doable in the future, that's what I tried to imply though. Akin to how they thought we couldn't fly, or how we created all these new materials to serve our needs, i.e. plastics: one day we might have staple-able water sheets!

Technically, we already time travel at a rate of 1 hour per hour. But, most interest in in whether we can time travel to the past of at a faster rate to the future, and return back to the present, like in multimedia from popular culture (Doctor Who, and Back to the Future), but, scientists say that this may not be possible. Taking into account a notion, created by Albert Einstein, called Special Relativity. This theory says that space and time are really aspects of the same thing which is space-time. There's a speed limit of 300,000 kilometers per second for anything that travels through space-time, and light always travels the speed limit through empty space. Special Relativity also says that a surprising thing happens when you move through space-time, especially when your speed relative to other objects is close to the speed of light. Time goes slower for you than for the people you left behind. You won't notice this effect until you return to those stationary people. For example, if you were 15 years old when you left Earth in a spacecraft traveling at about 3/4 of the speed of light, which is much faster than we can achieve now, and celebrated only five birthdays during your space voyage. When you get home at the age of 20, you would find that all your classmates were 65 years old. Because time passed more slowly for you, you will have experienced only five years of life, while your classmates will have experienced a full 50 years.
