Law of Conservation of Mass

[ScottyGEE]

So, we know that matter cannot be created nor destroyed. Check.

Antimatter?

But really, questions like these I never like, not only is it irrelevant to me but answering it does not give me any benefits either other than "oh that's pretty kool".

But I do enjoy reading stupid theories Not saying any of them here are though.

[guysullavin]

how come theres an experiment going on to try to re-create the big bang?
wtf?[/url]

[INSANEdrive]

Alright, I've been reading the Darkness Beyond the Stars. It's not a well known book, but it can give you a relative perception as to how large the universe is. Of how many planets there are, of how many stars there are.

So, we know that matter cannot be created nor destroyed. Check.
We also know that energy cannot be created nor destroyed. Check.

Yet at some point in time, vast quantities of matter somehow existed.

The question I'm driving at is, why does anything exist? Why does space exist? Why does time "exist?"
Why is there not a plane of nonexistence. In fact, the plane could not exist, so it would just be... nothing. Why is there anything?

Is it possible that all matter/energy has just existed? That matter/energy has had no start nor beginning? Because if there was a start, that would mean that it came from nothing.

It's an unusual question, and I've been thinking about it. And I know no one truly knows the answer, but I was wondering what other people's thoughts were on the matter.(hehe, matter)

Hopefully, you get what I'm trying to say. It's not an easy idea to convey.

Edit: Oh, and I would prefer that any religious ideas/theories be kept out of any and all discussion.

Big question...and one that science is still working on. Let me see here... I’m going to have to answer this one ( to the best of my memory's ability) in chunky bits. The answer is not an absolute because the absolute is basically... We have yet to truly say, "I know" (At least to my knowledge). There are (Currently) 4 Energy's that run the universe. They are Electromagnetic, Strong Force (nuclear), Weak Force (nuclear), and Gravity. In the Beginning it is said that in the first (Less then a second) These forces were united in one large super force. Hydrogen and Helium atoms formed (Not out of no where... they existed in another form). Then the forces started to separate. That plus the imaginable pressure and heat.
When paper burns it does not disappear I simply becomes another form.

And now I shall say this. Balance. Ebb and Flow.

I hope this can push you in the right direction. (And I hope I remembered and Interpreted this correctly >_>)
Guess what I think the answer is. Other than "It always has"

Try Googleing "Grand unification theories". I think that might help.

Edit:Massive particle collider passes first key tests

I kinda remember a theory by Stephen Hawking: we have observed matter and anti-matter "pairs" spontaneously appearing, colliding, and disappearing, yet the four forces don't work the same on matter and antimatter. Something might have caused the antimatter half of these pairs to fall into, say a black hole, leaving the matter behind.

As for the question "what happened before the beginning of the universe", the answer is that there is no answer. Time is simply another dimension, or direction if you will, in space. You cannot be "north" of the universe. You cannot be "after" the universe. Such terms only apply within the universe.

Same thing applies to Time. Time as we know it is a man made concept to catalogue a series of events. Time as a dimension cannot be defined with words we would understand.

[WaeV]

Have you heard of Lugwig Wittgenstein? He had some theory about language such that not only is our language limited by our world but our world is limited by our language. What cannot be thought cannot be expressed and vice versa (I think). It's pretty dense stuff.

[Philly]

God created the universe. Pretty simple.

Or if you want to think about it this way, the trigger for the sudden existence out of nothing must have been caused by something which the human mind cannot understand. Or something like that.

Stephen Hawking did some later work in which (for some strange reason) equations only work if you use imaginary time ( 2i hours, 3i hours, etc.). What was interesting about it was that he discovered that the universe could be finite in size but have no boundaries.



(Ignore the text on the above image.)

Picture the above image as the universe, with time starting at the "north pole" and ending at the "south pole". The universe starts infintisimally small, but as time goes on space expands, then shrinks (The lines of latitude). Without singularities. That's right, this is a theory for the creation of the universe without a big bang!

The idea is that the universe can be finite and yet have no boundaries just as the surface of the earth has a finite area yet no boundaries. There is no "before" the universe and there is no "outside" the universe, there is only what is within the sphere.

[Geo]

So, the Earth is the Universe. I see.

[WaeV]

Well, no. It's a metaphorical representation of the universe, in this case.

[CompKronos]

i think i have a little more elaboration onto that theory saying that the universe is finite but has no boundaries. first i present the Klein bottle, a fun two dimensional object that no top/bottom, i think it is a 4 dimensional object that mostly exists in 3 dimensions, or it is 3d in 2d. looky

more importantly the universe is actually 4 dimensional object that mostly exists in 3 dimensional space, also know as a brane (short for membrane). the 4th dimension being a spatial dimensional that is impossible to grasp any hold of with our wimpy human perception. What some guys at i think M.I.T. are testing is theory that when two of these branes collide they essentially explode outward, as they explode outward some of the particles hit each and start to clump up and create stars, planets, yada yada. Basically it like a big bang 2.0 deal. However if you can imagine and the way i like to think about is the universe is finite in the 4th dimension basically a circle, and what happens over time this cycle repeats so everything slowly goes back and re-collides with other branes again.

So the universe is then a finite loop in the 4th d, more like a chaos theory loop where it is very very similar but not the same, and then the "physical" unvierse has no boundaries, like pac man minus the walls, and so this cycle repeats, with it can be at the point of explosion what insane drive mention the creation of the forces at the start.

sorry for the bad typing but i am supposed to be in study hall and i really don't feel like doing two much fluttery formatting. oh the science experiment by the guys a MIT (could be wrong as to what university) i read about in a pop sci mag, W00!

Ten dimensions explained

[hollow121314]

I like thinking about stuff like this, its so mind boggling. So what exactly was before the "Big Bang"? It something that we will never know. Sure anyone can say "there was nothing" but how can you be sure. How can you be sure that there isn't anything on the other side of the anti gravity space walls. Its crazy. I wish there was some way of knowing but its just a mystery.

Ten dimensions explained

that was cool, definitely worth the watch

That was possibly the most amazing thing I've ever seen.

All existence started with a set amount of matter/energy. No more of it can be created, no more of it can be destroyed. Does this solve your existential quandry?

If there was a start to existence that would signify that matter/energy was created at one point. The impossibility of matter/energy to create themselves from nothing is what he was addressing.

[antszy101]

Anyone familiar with CERN and the LHC? This is one of the things they are looking into during their experiments. I know they are also striving to even create matter from the high energy released when the protons collide. I guess we will have to wait a couple of weeks before the experiments start to find out...

Earth is just a reality show.

Duh.
