The Universe

[Chaøs]

The one thing I wonder is how far it goes... it has to have an end, doesn't it?

[Meh]

Its hard to think that something has no end, but that is just because everything we know does end(few exceptions)

Yeah, Hawking also discovered that black holes eventually die because they emit a form of radiation (now known as Hawkings Radiation). All that matter thats sucked up and crush somehow exits in the form of pure electromagnetic energy.

And theory has it that two blackholes could connect and create a wormhole between vast stretched of spacetime. That means we could time travel back into the past (I'll draw a diagram if anyone is interested).

Last, it is pretty much understood that the universe is a large bubble and does have an end even though this has never been proven. But because everything inside this bubble is a medium in which we travel we could head to the edge of the universe in a strait line yet loop around the bubble forever without even knowing it.

Sounds interesting, diagram please.

Kinda like Wilson from Home Improvement?

We are just doing the special and the common relativity theorie at scool, and i find this pretty interesting. Did you know that moved objects look rotated for a resting viewer? it's sooo cool

Teapot somewhere...

Lucky you, I found one on the internet. If I had drawn it, it probably wouldn't be legible in anyway.



So the flat, green, grided sheet is 3 dimensional space (its just flat in this diagram to make it simpler to understand). On the top and bottom are blackholes making enourmous dents in spacetime because of their massive gravitational pull.

Einstein's General Theory of Relativity creates the notion that gravity is not a mysterious 'force' but a warping of space time. Its like are if you stretched you t-shirt out to make a large flat surface but then let a ball roll around ontop. The weight of the ball causes a dent in your t-shirt that as you could, extends all the way through the fabric. That means gravity has an effect on things thousands of miles away, no matter how dimished the strength is its still there (as long as they're all on the same t-shirt).

When 2 black holes conviniently get near one another, they'll be attracted to one another and cause a link. When they connect, a hole opens very briefly, and is only sustained if there is the presence of negative energy. In the diagram, it might be hard to tell, but there is a point A next to one black hole and a point B next to the bottom one. Lets say point A was earth and point B was Pluto. Light, or information, travels from Earth to Pluto in 10 minutes using the long and curved way through actual space time. You on the other hand are in a rocket ship and leave at the same time your light does, but you take the wormhole. Since you get to Pluto in half the time it took the light because it was half the distance, you could actually stand on Pluto with a big telescope and see yourself boarding the spaceship on Earth and preparing to lift off.

But of course thats only oscillating electrons, or light, that your seeing. Time travel itself is actually not possible, you can cheat to go from point A to point B faster than light can, but you can't actually go back and change the past or interact with it. Why? Well I can't explain it very well, but try going here: http://forums.hypography.com/physics...ed-v2-1-a.html

white holes and new universes or matter just dissapears.

in my opinion i have a theroy (i mean whos gonna listen to a 16 year old in the world of science thjough: what if space as we know it is sort of on a plane that could be compared to the surface of water. and as we know surface tension holds light things up (leaves, bugs, ect.) what if the black holes were like straws that sucked up objects and mass when they became to heavy to hold up on the tension of our water like plane. and all the objecst were still there in our plane when it closed, like in a cosmic bubble or they sink to the bottom of our plane.

any thoughts?

His name is steven hawkings.

no it's constantly expanding at an increasing pace it's about 78.1 billion light years across right now.

and the pace is increasing due to the fact that dark matter and anti-matter make up most of the universe and they have an opposite effect on gravity.

There is a reason as to why it is hard for us to think about the universe having no end. Humans in general are used to thinking that everything has an end, because everything we see and do has an end. The human eye and mind only perceives...well....what is open to it.

It is very possible that the universe does not have an end, and yet, it is possible that it does. But then, what's beyond that? Once again, the human mind, out of instinct, wants to think that there is something beyond the end of the universe, and that it is impossible for there to be nothing at all. What if there really is nothing, and we cannot visualize it because humans have never seen nothing? It is a possibility. Of course, there is also the possibility that our universe is an incredibly tiny particle compared to whatever else is out there, if there is anything else out there. There is a possibility that the universe compared to....the 'big picture' is exactly what humans see atoms and themselves to be, but on a much larger scale.

I've always been extremely interested in everything to do with the universe, so I like it when a thread pops up about it in Y&B :D

Not that much. What do you guys think on other intellegant life forms?

Well, personally I've never met one... but they seem like they could be some pretty cool guys to hang out with.

Seriously though, I think it would be foolish to believe that there isn't any other life out there than on our world. I mean, if only one in one million stars had planets, and only one in one million planets were a suitable distance away, and one in one million planets a suitable distance away had the needed things to support life, and one in one million of THOSE planets had those things come together to support life, there would still be a huge amount of inhabited planets in just the galaxies we know about.

possible i mean whos to say with all the billions of stars not ONE has the abillity to be formed like us? there could be a race exactly like us or a smarter one (maybe a stupider one too). we don't know even 1/12000000000000000000000000000 there is to know about the universe i mean its all just theories and graphs.
