Time Travel

Possible?

Well, i might not be the appropriate person nor someone in position to explain on those physics theories (which i dun even understand!), but i'd still think it is possible.

Time travel to the past is theoretically allowed using the following methods:
Traveling faster than the speed of light
The use of cosmic strings and blackhole

Wormholes and Alcubierre 'warp' drive

What the heck are all these? Ok, i tried to understand the logic behind all those explaination i could get over googling. I used to think alot on these when i was studying in primary school, being too much inspired by some fantasy movies...

Over the years, people came up with lotsa ideas to deny the possiblity of time travel.

One of the popular questions - If time travel is possible, why is there no visitors from the future?

I guess this classic question has been answered. There is already a technology that can make anyone invisible, thus, besides 'future beings' can simply disguise as 'present beings', they may also make themselves invisible if they are to travel back to past. As cool as that.
