Border of the universe?

Post Reply New Topic

Nah its fine, i was getting at the fact that string theory got its name from the way the strings were first described. The strings emanating from the extra dimensions were described to be very thin, so thin that we cant interact with them but they could be described to each have unique length. Hence "string theory". Of course i don't mean length in the classical sense, rather length measured through time and space.

Now the strings are described in two states, closed (loop) and string. As said the so called "vibration" of the string is said to correspond to the particle it creates in our 4 dimensions.

So i suppose you could look at our 4 dimensional existence as kind of like a shadow on a wall...

Lol

Everyone must have seen that image by now but as the old saying goes "a picture is worth a thousand words"...

If god exists and the universe was created for humans he made way too much black stuff...

A being who lives in the water/air surface of the ocean and can only "see" surface waves can not look to the sky and see that he already lives in the border of the Earth.

But so I shouldn't picture those extra dimensions from string theory as directions which we are unable to see? And strings are only two dimensional right? But I shouldn't think that we are like flatland to the fourth, or fifth dimension?

By the way, everything outside the border of our universe should be nothing, because the fundamental laws and forces of nature only exist inside our universe because they are bound to the dimensions of our universe, right?

If there are in fact multiple universes, there could be other fundamental laws and forces in those universes, we don't even know for sure if our universe has only the four fundamental forces of gravity, the electromagnetic force, the weak and the strong nuclear force, but we have observed those and think we can explain everything using those four forces.

So to my idea we can see the universe as a system that we can explain using laws, and outside this system there can't be anything except for if our system is part of a bigger system, but we can't know that until we are able to even get to the border of the universe but I don't think that will ever happen.

You can interpret the strings as being two dimensional but its very hard to picture the nature of the 7 extra dimensions as we have no real concepts in our four dimensional realm to explain them by. That said, i did read an article where a computer "map" was made of the extra dimensions but i cant find it right now.



That is correct but your thinking too human lol. As said, the uncertainty in the early quantum scale universe gave rise to every possibility being fulfilled so each reality took off from there, the multiverse. Much like an electron can have an infinite number of possibilities/positions so too could the quantum scale early universe. The almost infinite number of universes each went their own direction from there.



Correct!



There is probably no outside system(as yet lol), rather different iterations of the same universe(kind of). The "border" might be closer than we think

Hehe.

The Universe has no borders.

And some would argue that if there is no God then a lot of real-estate is going to waste.

That is one of the lines in the motion picture -Contact-.

How is it possible that you can spell finite but not infinite)

What a pointless post...

How is it possible that you can't punctuate correctly?

The typo i made was made on my droid. Saving a typo is as easy as pressing space. Then your stuck with it until you notice yourself or some bored smartass (who can't punctuate) points it out.

Universe.....endless imo also

Visible Universe....view back into space time. the result of "our big bang" and a very beautiful place

Big Bang......super massiveblack hole gone super nova?

Dark Matter....remnants from big bang (smoke?) or possibly the matter of the universe outside of the visible "our universe"?

one of my interests.."astro physics.. theory"

The void outside the influence of light and gravity is infinite, the matter/energy in the universe is not.

Infinite matter/energy violates the second law of thermodynamics, and the arrows of time.

The universe is not a perpetual motion machine.

All science thus far is merely perception. What we can perceive from a tiny planet on the edge of a galaxy floating somewhere in the universe.

We don't know if the universe has an edge since by the time we can actually observe it, it's billions of years old and thus what once was, might not be.

Still, to f**k with your heads a bit...what if black holes lead outside the universe, thereby creating their opposite, the white hole. A white hole would essentially be an inversion of all physics we know. Or perceive.

Riddle me this then. What would the edge of the universe be comprised of? Radiation? Dark matter?

Or maybe this Universe is god's left testicle.

What edge?
