It has also been theorized that while it may not ever be possible to go back, travel to the future is possible.  We have all heard of the example of a space traveler approaching the speed of light.  Well, the speed of light could be harnessed that way for time travel.  There may be other ways as well, but I don't know of any.

I joked about going through a wormhole, but that theory is not as far-fetched as one might think.  Wormholes are basically a tunnel through the fabric of space.  It is easily as possible that they move through the fabric of time as well.

Wormholes -R- Us is having a sale this weekend.  I thought I might pop down and pick some up...

What I'm talking about is that the closer you get to the speed of light it slows down.  I must have been too vague.  Since it does slow down (it has been proven with atomic clocks) then the speed of light could be used as a one way time machine.  The usual example is that if a person left Earth for Alpha Centauri travelling close to, but just below, the speed of light then while a 4 year trip occured for him, 100,000 years would pass here on Earth.  My numbers may be incorrect, but you get the idea.

...as usual...
I'm with Hagar on this one.... ...!
Time travel malarky just gives me a headache.... ...!
LOL...!

Paul.

Pippin....you are watching way too many Star Trek movies, and they are modifying your normal common sense.... ...!
...Time travel....housing estates on the Moon, etc....whatever next...?
LOL...!

What if you killed yourself in 1968 and didn't return took the future, but to your 1968 self's place?  Does that mean in 2003 you would have to go back and kill your self again?  You would still be in a cycle, but every time you went back you would be 36 years older.  Pretty soon you would die of old age before you could come back...

Alternate dimensions do exist IMHO.

However, the problem is how to get to one of them.

In a Popular Science magazine [or Discovery Magazine], there was an article on how Alternate Dimenstions or Parallel Universes exist.

It is possible that each parallel universe in the entire multiverse is so far apart that even if you do travel at the speed of light or faster, it might take you centuries to even reach your closest Alter Ego [other self].

Remember, our parallel universe contains more stars than all the gains of sand on Earth. Not only that, each star is about thousands and millions of light years apart from each other.

Not only that, the distance between the boundaries of two parallel universes can possibly be up to billions, trillions, or even quadrillions of light years apart.

So, do the math.

Like you said, anything you do or didn't do can effect the infinite worlds that parallels your world.

For example:

Let's say you were driving a Farrari in the middle of the night at high speeds. All of a sudden, you run a red light and another car hits you and you die.

Then, almost half [possible more] of your Alter Egos would probably do the same thing you did while the other would probably be acting more carefull when they drive at that same moment.

Or, some or a few might not drive at all while the remainder may drive at a later or earlier time.

As you are reading this post I have just made, my alter egos are probably doing the same thing but with some minor differences in the posts.

Just before I posted this message, I had to check my text before I posted it. I found out that I had to add a few more paragraphs or words to this post.

While I was tyoing this post, my alter ego was probably not careful on what he types on his post.

I once saw a Morlock chase an Eloi across a field...then it looked at me so I came back.

I understand that there are not that many people who believe in parallel universes or time traveling.

Most of you have only been using a small formula for this matter.

In the many articles that I read about this, many researchers have used formulas that are complicated as the SAT exams. ???

They would thing of something like:

E=D^2[X/3+5]+M*A......blah blah blah. I have seen these kinds of formulas and they have confused me.

The only formulas I know are:

D=R*T [Distance is equal to the Rate multiplied by Time]

F=M*A [The force is proportional to the Mass multiplied by the Acceleration]

E=MC^2 [The Energy is Equal to the Mass multiplied by the "C" squared] I don't know what the "C" stands for.

A^2+B^2=C^2 [The pathageream theorim. By Pathagerus]

A=L*H*1/2 [The area of a triangle]

These formulas, came straight from the top of my head.
