NASA has successfully steered an empty rocket hull into the moon's south pole in a search for hidden ice. (Oct. 9)

Shows footage of the thing from what I understand. Can't open it while at work.

Oh, these things would have happened millions or more, years ago, Earth time. Time is interesting, it's all relative.

I have long pondered the concept of time. Why is it linear. Why can we remember the past and not the future. Is it linear?

Because we perceive things on the third dimension and travel in the fourth. If a first dimensional dot perceived things on the first dimension while moving along a two dimensional line, it would not be able to look "ahead" because it only travels along the two dimensional object, it does not perceive it. At any given moment, it only exists in the first dimension.

Just as at any given moment, we only exist in the third dimension. The progression of these moments is the fourth dimension, or time.

if you were to go back in time and change something would it affect the future, or create a new one? Is time travel even possible? If it were possible, what good could come of it?

It depends on what the fifth dimension is. Theoretically the fifth dimension could be "possibility" if you believe in the many worlds theory. This means that for every true or false condition in the third dimension which occurs at any given moment in the fourth dimension, a new "universe" exists. Really you can sum this up by using the same examples we used above: past, present, and future (time) can only perceive past, present, and future (time) thus making it seem linear...but it travels along a 5th dimension, which would be a combination of every possible "timeline".

So take that and think of the words "time travel". Now make it "fourth dimension travel". We already travel through time as it exists from a third dimensional perspective. We would actually have to travel along the fifth dimension, or "possibility travel" in order to accomplish what you think of when you say "time travel".

How does time react ot variouse things, like moving at the speed of light, is there a way to cirumvent or bend time? All intiresting questions that hopefully we will someday know.

This is where relativity comes in. I mean, I suppose if you were to travel to a star three million light years away within a blink of an eye, technically the light of that star would not reach the earth for three million years and therefore you would be traveling three million years into the future...relatively.

But we can waste lots of time talking about relativity. Right now you're sitting at your computer reading this, sitting still. Or moving 66,000mph around the sun...or 43,000mph or so toward the Lyra constellation...and relative to the center of the galaxy, roughly 483,000mph...and relative to the center of the Universe, a supposed and hypothetical 1,300,000mph.

Of course, Einstein would argue that relativity is much more meaningful and that quantum mumbo-jumbo is the waste of time!

Excelent post VBsnus, and I had read about what you are refering to in Brian Greene's "Elegant Universe", and excelent read.

Relativity is an amazing concept and hard to wrap your head around sometimes but Einstein made an excelent point in his theory of relativity.

I really wish I had the time/money/ and intelligence to get a Phd in physics or a related degree just for my own personal knowledge. Maybe someday when i'm rich 8)

Very good VB.

Since you're interested in this - have you heard the recent theory that dark matter might in fact be other universes pressing on ours - they liken universes to bubbles, like soap bubbles in a bath, lots of them, expanding and pressing into each other.

Quantum physics is throwing up some extremely interesting and mind boggling theories. I think as far as time goes they reckon that the future already exists and that the present is interacting with it - never mind the 'parallel universe theory' - all thought provoking stuff.

YES! I have also heard of this, however the version I had heard was not the soap bubble one. It was more along the lines of there being two planes that start out stacked like 2 pieces of paper but are part of a continuous cycle in which they expand away from each other and then recollapse, each time they collapse cause a "big bang" type event.


@VB

Ulsterman's version of how time works is the theory I was refering to. Many believe that time is as you descibed since that obviousely makes the most sense. But there are some intriguing theories that propose different views on how time works that I find fascenating. I hope I am alive when the next Einstein comes to the surface.

[VBSnus]

I like soap bubbles better than a tree of timelines which I referred too. I imagine it as the ultimate Venn diagram, with an exponentially growing number of bubbles merging and separating at any given time. Quite elegant, actually.

I always wondered, we assume outselves to be the highest level of intelligence because in our current habitat we seemingly are. But we havn't even seen anything outside of it really. Everything we see in the stars are really just snapshots of what they looked like billions of years ago. Who knows what the universe even really looks like if you went out there.


And who says just the known universe is the end. What if our whole universe with all of its heavenly bodies rotating around one another with vast spaces in between are just atoms in an even larger construct. Perhaps we are even to small and insignificant for other "life" to ever be intirested in us at all. Perhaps it is a never ending system of universe upon universe?

I guess it doens't matter because at the moment I can barely figure out how to beat the new South Park Tower Defense Play on Xbox 360. But nice to think about.

One of these days the moon is going to strike back and kick our ass.

I, for one, welcome our new moon based overlords.

I dug out an old paperback book I've had by Zacharia Stichin to try and read, since I never got to it.

Cool cool.

You like Art Bell?

I used to listen to him all the time, and listened to George Noory for a while to, but at least 90% of that show is all fringe stuff that is kinda out there.

Most recently this guy was claiming that if you use night vision goggles to look up at the stars you can see UFO's fighting battles against each other invissibly over the sky. Now I will give it to him that when l0ooking at the stars with NVG's at night you do see some pretty weird stuff, and me and my aprtner while in training in LA we both thought we saw a UFO, but frankly with the kind of aplification those new 14's give, it could very well have been a moth or bird flying really high.

Trust none of what you hear and half of what you see

Seems results of this are just now coming out, and it appears the moon is covered with water.
51 billion gallons in just that one crater that was hit.

That was before Congress approved a blueprint last month for NASA that shifts the focus from a manned moon landing — as outlined under President George W. Bush — in favor of sending astronauts to near-Earth asteroids and eventually Mars. A return to the moon could potentially be a way station — something still to be decided — but the moon won't be an overall goal.

because we cant land there?

[tom502]

Seems so.
