regarding time travelling paradoxes in the first few pages of the thread, how do we know that its not happening now? how do we know that there arent anybody constantly changing our present moment now? How do we know non of the results of the various wars on earth havent been 'fixed' ?

When these changes happen we wouldnt be able to tell right? i'm totally noob in this subject. hope i dont sound too stupid. icon_question.gif

Well, that's the problem. We don't.

And so we did not assume.

However, if you are to say you come from your past. You killed your grandfather, then you cease to exist. Then who killed your grandfather in the past?

There is theory, however. That even if you killed whoever conceived you, you will still exist.

The theory suggests that time does not really move in a straight line like an arrow. It moves likes a river, in different sets of streams. At times, the river can split into different directions, resulting in different timelines, or else known as the explaination for parallel universes. This theory is probably oming from an everyday human experiences. Have you remebered how certain minutes actually "felt" as if it is longer than other days? Theory suggests that the river sometimes forms a small vortex, trapping any matter into a temporary time stop, hence you hear things like, "That is the longest ONE minute I ever have".

Theories, anyways. But it sure gave a way out for time paradoxes.

You mean such vortex only slows the clock but not human or animal? When we need more time to do something, it is faster but when waiting anxiously for it to pass, it seems slow, how does scientist conceive the theory?

It is still a theory though, and their explaination is that time sometimes create vortex in the river of time, sometimes you just feel time is actually longer that it should be.

I still don't get this vortex time theory, I only remember time keeping device have only adjusted less than a second because the minute & second is not perfect measurement. If it fluctuates in such that we can feel, how to be certain that the Voyager or Apollo mission won't be affected by it? Imagine the satellite went off align by one minute.

Unless it only affect cosmic and device but not living organism because we have feelings, what kind of science is that?

I regret I do not have fully understanding of this, but I was interested because I saw this video:

regret to tell u that your pov was totally wrong. i'm the man from future. 2079. However there are nothing i can do to change the past, simply because of it became our history. it was merely a trip to visit my grandfather that pass away long before i was born.

Really? So how's 2079?
