Scientists say that space, time and matter originated 13.7 billion years ago


If the universe expands and collapses, it seems to me that the big bang happens every now and again, which means it happens more than once. If that's the case, what they found out is the most recent big bang happened 13.7 billion years ago. There's no saying if that is the first big bang or not, and if it is not, then space time and matter didn't originate 13.7 billion years ago, but much much longer ago.

Thought they finally decided that the universe won't collapse back on itself, that its actually moving apart... and speeding up. With the conclusion that we will speed up until even atoms become unstable and break up. Meaning no constant universe, the opposite actually.

Anyway, thats what discovery channel (im pretty sure) stated on naked science.

Or maybe the universe was created when two other universes collided creating the big bang and existence as we know it. Welcome to the multi verse son. Really though, we will never know if the big bang happened with physics as we know it today. Physics breaks down at the exact moment the "big bang" occured.

Or you are becoming sane, finally. Waking up. I suppose only a few are aware of all this. Isolated persons here and there. But the broad masses... what do they think? All these hundreds of thousands in this city, here. Do they imagine that they live in a sane world? Or do they guess, glimpse, the truth...?

Gravity is inescapable. There is no point in the universe where you are not atleast a little affected by an object's gravity. I do not understand how the universe could possibly be constantly accelerating, unless there is an outward force on each object in space (which you would be hard pressed to prove). What I can see is when everything explodes, there is a period of accleration, but the universe's center of gravity slows all outward bound objects until it comes to a rest, and then falls back towards that center (and clumping up with other space objects along the way).

The reason I can see this happening is there are two types of forces acting here. One is a pulse force or conservative force, the big bang. The other is an nonconservative force, gravity. The thing about the big bang is it puts an accerlation on all objects, and then stops. Gravity puts a constant acceleration on all objects. So if you have a constant C accerlation on all objects from the big bang, and then -X acceleration from gravity (negative because it's in the opposite direction), and assuming C is initially greater than X (which it has to be), you get C - X at time 1, C - 2X at time 2, C - 3X at time 3, etc. And since these are all acclerations, at anytime C - bX, where b is that incremental time constant, is greater than 0, you would have accerlation. However, once it becomes less than 0, the universe begins to collapse back into itself.

The kicker is, however, as distance becomes greater, gravity becomes exponentially weaker (so X is not a constant, but decaying as time goes on as well). But it never goes away, and because of that, the kinetic energy of the universe is being drained back into potential energy.

So actually, I would just like to know how it is possible the universe is constantly accelerating. You cannot create energy from nothing. And if the universe is constantly accerlating, kinetic energy is increasing for no reason at all.

Yeah, honestly i always thought the way you did, but on naked science, the guy said that through studies and stuff they have determined that outward objects are actually speeding up, not slowing down. So either they just did the wrong calculations or there is something else we haven't discovered yet for the speeding up.

i say there is something out there with greater gravity than the pull of our universe.




btw, off topic, but curiousity.... since they can calculate the trajectory of where everything is going and how fast, have they been able to figure out exactly where in the universe the big bang happened? or do i have my proportions of how big this shit really was all skewed?

if i were on my machine i would put a picture of the milky way on a pokachu covering its head.

someone do that for me.

0 BC.... the same as 1 AD isnt it?



BC- Before Christ

AD- Anno Domini (sp)



thats what I was always told these abreviations stood for when I was in private Baptist school. Is that what the secular world thinks they stand for also?

in my understanding there was a "Zero" year, but i read about that back in 2000 when people were trying to decide whether 2000 was the end of a millenia or the beginning of a new one. stupid debate really.

but my real reason for posting was

infinity exists

The crazy part, is that they screwed up the calendar when they figured out the bc/ad time line. Jesus was actually born on 3 bc, or so many "experts" claim
