Another factor that suggests the rate of expansion is increasing is red shift. When we look at light from distant galaxies, we find that all the frequencies are shifted towards the red end of the spectrum. In other words, the frequencies are all slightly lower than they should be. It's the same effect as a car horn sounding lower-pitched when the car is travelling away... this is known as the Doppler effect. Measurements of the red shift suggest that all the galaxies are moving away from us very quickly - and it's the same in whichever direction you look in. However, more distant galaxies have greater red shifts than nearer ones - which means that the more distant galaxies are moving away faster than nearer ones. Following the pattern, it is almost definite that galaxies even further away (ones which we cannot see) are moving away even faster (otherwise nearer ones would collide with them). So if the further galaxies are moving away faster, then the further out you go, the faster the rate of expansion - so the universe is expanding with an increasing rate.
You don't say? might I add that when you look so far out in space you look at past events? wouldn't it then be logic that the longer back in time you go the faster the rate of expansion? So you are infact NOT making any sence what so ever.
You can carry 2 persons i think, It's just extremely hard. But it's still a good answer.
Hey, couldn't the "Welcome to mathsisfun"... Be a road sign?
Ah, that question. Honestly, I don't think the universe is expanding much more now, It's just the heavy mass in the universe from the big bang that continues expanding into the universe.
The universe is increasing its rate of expansion. And we also know its not just matter moving around. Everything is moving away from everything else. The only way this is possible is if space itself is expanding.
"The universe is increasing its rate of expansion."
Why don't you show me how this experiment was done. I mean it is not working with andromeda and the milky way, cause they are moving towards eachother, and that's odd, cause they are the somewhat latest in time: there is a lot of difference between negative escape velocity and faster then overlightspeed. Cause the big bang expanded in overlight speed. Or, yes, you want to refute that now. Who doesn't, I have also, it's just that it wasn't welcomed.
On Monday it will be sunny and the temperature will be
please kindly tell everyone you know.
The funny with this joke is that it is both impossible and contradicting, not to mention very "We are all gonna die"ish
From what most of us knows today anyway. There might be some special ecception somewhere, in exotic matter for instance.

hrhrm. the new post count rule...
the post has to be big.
Okay, let me make a guess myself, the universe firstly was inf dimensional, but not a non-vanishing continuous vector field. So it decayed into such and by doing so, it split into space and matter, not to mention exotic matter of all kinds. Obviously this caused a big bang, since all things firstly existed on the same spot. now instead, all things, surounded with nothing but eachother, hence next to eachother, only experienced the dimensions that they had and not those who were before. Which in its turn led to the experience of a neverending space and an unteeming amount of matter, almost instantly.
"Philosophy is a game with objectives and no rules. Mathematics is a game with rules and no objectives."
Honestly. It sounds good but it isn't.
Anyway, I find it hard to see how a continuum can lack a beginning. Another conclusion I have also drawn: Beginnings begin and if it is not the beginning that begin, then it is not the beginning. But I employ you to draw the conclusion that we move through the entire time continuum, not "all - 1 plank length". -Gngngngnnnh almost, but not quite!
It was intended. It was also partly a joke.
Let me get this straight, In the beginning, time did not pass, cause everything was so incredibly dence. Then after some time had past, everything exploded into a non existing room. Suddenly, gravitons where created from some special particle fusion, even though they had no reason to do so and got control over the universe. what more, electrons and protons got created and ever since then they have been attracted to eachother.
The question then remains, why didn't they settle this in the beginning?
This is what you do. Point at the woods and say "LION!", the blue eyed chmucks will run away Collect alot of wood, and put on the 2 boxes. pour your last liqour on them, take a pair of stones and ignite. the snake will now burn, but the speed boat keys remain intact. take the snake as provision, but be sure to cut of the head and take the key from the other box. Insert key in little hole and try 2 get as far away from the boat owner as possible. after all, he had a deadly snake. Then call for aid on the radio.
No. Well yes. I just wanted to ask you, do you trust me, puppet? (kidding)
This is REALLY good, therefor I want to be a "Real" member. If it doesn't take too much disc space, that is.
ok, there is no end and if there was one it wouldn't be relevant/important anyway. I just look of it as every time exists or will exist anyway.
Atleast I meant that it would take an infinity for it to reach the other end. I just had breakfast, sorry for the interruption.
I guess the answer is that for the thin moving on the line, the line is never ending, but what about for the line?
Imagine a line with beginning and end, now imagine something infinitely slow moving on it, and that is all there is. Does the line have an end?
Yes, but there is an end even though, yes, we will never reach it.
if there is a point of time to reach, doesn't that mean that the point of time allready exist, it's just that the end time never will be reached?
It will, it's just that the time between now and then will never finish.
It could not be something, instead there was nothing. a dot with 0 length in all directions, since nothing has no limits, since then it wouldn't be nothing. but the inf dimensional dot decayed to many lesser dimensional dots called space and mass, and they in there turn will possibly decay too, until the universe is 0 dimensional, which will take an infinitely long time.
Here's another theory:
There is a 3-d shape that is the 3-dimensional equivalent of a Mobius strip; the shape, resembling a jar, has only one surface and no edges. Perhaps the universe could resemble this.
Yes, and the mobius got the lot of us!!! (kidding)
PS. mobius is one of those small buttmouths right?
If what you say is true then electrolux is going down in the long run, right?
And ice machines, will they be illegal? (kidding)
You don't think... plastic clothing shares up?
Space is like weight, if one is nothing, so is the other. If you say that, all you end up with is a bunch of nothing!
