INTERESTING FACT
Travel Back In Time?
Ever since H G Wells' 'Time Machine', time travel has been the topic of science fiction and has fascinated human minds - young and old alike. However, modern say research in physics shows that this actually is not possible. Particularly after the revolution of the theory of relativity, it is known that space and time are intertwined in a complicated manner such that any body that has mass causes the space-time around it to curve so that it accommodates that body with mass. In addition, although, you can move forward and back in any of the three spatial directions, you can only move forward in time.

Please wait...





And also, would black holes be worth a mention?
I'm not sure about these though :S
Mark Fleming photographer?
when we bounce a rubber ball it will not continue going through my floor but it will bounce back
but overall completely true...
There are countless theories behind this, but i love a good philisophical/physiological debate, so I'm going to share my theory...
We are are alive and in a 3 dimensional world, we are only able to perceive time as a linear concept. In order to reach the ability to "travel" through time, we need to leave the 3 dimensional world (through meditation, death, or however you want to view it). We would then reach a state taht is beyond human comprehension, between existence and non-existence. It is this plane of existence where we could perceive anything and everything all at once, do anything, and go anywhere.
I think that when we discover a way to communicate with that state of existence (ie: talk to the dead or capture them ghostbusters style) will we then be able to travel through time.
Or a delorean with a flux capacitor, whichever comes first.
One of the most fundamental properties of the universe is change, which defines time. Obviously the universe now is very different to how it was 13 billion years ago, and this is surely not possible without time.
Time is not merely a subjective, human concept. Time passes objectively and indisputably, which is why processes such as red shift are detectable.
As for your second statement, 'of course you can't travel through [time]', every single person who is alive at this moment is doing just that.
In physics, theoritically, forward time travel is possible at higher speeds (speeds close to the speed of light).
Cosmic theory says that one can shift dimensions (through meditation,..., etc) which will allow a person's mind to go back or forth time.
