Time-travel possible?

[Rota]

With how we look at time, and think of it, as a notion or a concept, time travel is impossible. Our time is based on the rotations of a big piece of rock that revolves around fire. We could simply stop rotating and our time would cease to exist..or at least cease to be accurately represented. So, with this definition of time, that really has nothing to do with space, we can't time travel.

Our choice of measurement for every dimension is entirely arbitrary. Time would still "be."

Look at how we measure math (base 10 system)....
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20.

Let's say there's a civilization with a base 8 system instead...
1, 2, 3, 4, 5, 6, 7, 10, 11, 12, 13, 14, 15, 16, 17, 20.

In our system, 7+7=14
In the other, 7+7=16

Both are correct answers, even though they are different numbers. The measurement system in the two number lines is totally arbitrary, but the MATH is still the same. No matter what number system you use... when you add the 7th number on the number line to itself, you will answer with the 14th number on the number line.


Time measurement is the exact same way.
Our hours/minutes/second, etc. are just haw we measure time. We could change to some oddball metric time with 10 hour days, and give each hour 100 minutes, and give each minute 100 seconds. The definitions of minutes and hours and seconds would change, but the actual measurement of time would not. The only thing that changes are the terms we use to communicate observations of time to each other.

That' the point, isn't it? How o we know the same doesn't apply to us-that there are additional dimensions we don't comprehend-in which we do, indeed, exist?

I completely agree with you. I can guarantee you that there are dimensions we exist in, that we don't know about yet. As our race's knowledge grows, we will find and define and measure these dimensions, too.

Do you think its possible?

edit: I just need to stop a moment and say

THANK YOU, CRIP!!!!

This thread is the most fun I've had in months. I want to also thank all the participants for getting my synapses firing again. I love this discussion. I see lots of people bringing their A-game to the table, and I really appreciate it.


I thank you all with lolcats...
