The big mistery of liFe.... NO NOT WOMEN THIS TIME!!
 

The Fourth Dimension!! What is it?? Does it exist???

We all know we live in 3D. While we can think about 0D (a dot), 1D (a line), 2D (a what's it called in English), and of course 3D, we find it hard to think about 4D.

I've been thinking about it a lot. The fourth dimension is a new direction. Not up, left or forward, but somewhere else. But going that way, we could make short cuts...

I believe there was this 4 dimensional game somewhere on the internet... very vague, with an arrow that has to shoot through a hole... :confused:

There are also impressions of 4D objects. I'll look for it after I finish my tentams this week.

BTW ask your physics teacher about it... :D

edit: thanks Fingers... although the correction doesn't show up in the title on the General Forum.

I thought the 4th dimension was time.

Neways..............it should be life instead of live in your thread heading. :D

Its probably something similar to a "worm-hole" where it (like you said) is a shortcut somewhere, but you go in a "different way".:unsure:

I don't believe time is a true dimension. Just a measure we use like weight. Weight isn't a dimension.

Hmm... I tend to stay away from these things. It's times like these I had a big sign saying "I'd rather be gaming!".

But... really, the 4th Dimension would be Time itself. I'm also pretty sure it's impossible to describe..

some people say that it's time, some say it's temperature, some say it's something else :p. since any point in the universe can be measured, by up/down,left/right, forwards/backwards; itcan also be measured by temperature, and time...

i couokd draw a 4D cube...it's not that hard...but it is kinda hard to see on a 2D surface...so yeah...if i get around to drawing it, i'll post it here...

Time is directly tied to all space and matter and it is as malleable and evident as the computer in front of you. Time is more than simply a measurement. If it were, all time would pass by at the same rate, and it does not.

Take a Mayfly for example. Mayfly lives for only one day. But a day (24 hours) is purely a fabrication that man has developed to gain the illusion that time is measureable using the sun. That Mayfly may only live a day to us, but that same period may be a complete 70 year lifetime to the Mayfly in comparison. As Einstein pointed out, all time is relative.

A wormhole is a singularity in time and space. A pinpoint of such mass that the forces it attracts literally pull time and space into it until it impodes, creating a tunnel between to areas of the universe for instantaneous travel (if a vessel could ever be invented that could withstand the forces inherent in a wormhole). This was explained a little in Dune with "folding space".

So if time could be bent, could it be destroyed or even shaped to our liking?

*realizes he's gotten WAY too deep in this discussion*

Well, something to think about.:D

Time is generally treated as the 4th dimension, but it can also be things like temperature. It just depends on the problem you're solving. The 4th dimension isn't a thing in and of it self, it's a mathematical concept we apply to make life easier.

.....yes....:sneaky:

very true

from what i know there are like 7 dimensions but i dont know anything about them

I think I remember 4D being time. I think Angrist is talking about the 5th Dimension.

Some scientists actually believe there are up to 10 dimensions, and that there could be more.

The whole conecept of a 4th dimension kinda scares me...

Really though, I don't think we'll ever find out anyway.

Don't people put the infinite-dimesion theory to work? I've read many theories by smart people, where there's countless dimensions, and in each dimension, it's a different, well, time. All of these dimensions could be known as Time itself. Well, I'm more of a fan of quantam physics and theory, however... because then could anyone imagine a 378943638D?

Well, in this big old Universe of ours, anything's possible.
