OK, there's that saying, "Nothing is real." right? (tell me if I'm not making sense) Take that statement to heart, if nothing is real, then, i guess, we should be able to bend life/anything to our will. This means immortality amongst other things. Problem is that we haven't made machines or anything to bend the 'fabrics of time.' This was just an interesting thought I had last night.

Try to understand. [bl:)]

Deeply important questions for an immortalist.

Can we alter time? Can we invent a system/machine that is capable of this?

I think, in short, Yes. How soon and how will it be done are the big questions.

Here's another thought o' mine. If you had a twin and you went into space for a long time then came back to Earth, your twin would look and actually be older than you. Why? Maybe scientists can 'freeze time' like that.

You would benefit by a visit to the physics and space forum seanit. Once there see how much you can understand about Einsteinian Relativity.

Time isn't "frozen" except possibly inside "Black Holes" though there are questions about that too. However the "rate" of time is influenced by velocity relative to the speed of light. As you approach the velocity of light 'C,' time relative to the earthbound sibling is perceived to slow down, that is why it is "Relative." This is one of the classic paradoxes of Relativity as a parent could go into space and return younger than their own child after a period of a few years of transit near light speed.

There are a lot of variables that effect time velocity is one but gravity is another as it is a form of 'acceleration.' There are more than these but it is these that you are referring to in the example you are giving.

Thanx a lot. I didn't mean frozen literally, though.

Hello everyone, I hope you all had great holidays

One thing I'd like to point out is that, should we managed "bend matter" to achieve absolute immortality, then time will have no meaning at all : in essence, through matter we can bend time, or even make it "stop", at least as far as we are concerned.

I personnaly consider time only through its effect - entropy - and so if we reverse entropy (or otherwise modify its rate) we can reverse (or change the "speed" of) time somehow.

I think time travel is impossible because it violates causality (yeah, I'm not very original here...) but what really matters is the effect of time on the universe. If you have full control over the matter in the universe, you can undo events without having to break causality.

Maybe that's why time can flow at different rates : because it's only dependent on own matter behaves. Maybe causality is the only thing there is, and entropy is what seems to give time a unique direction.

Arggggg.... blasting a few neurons here...
