Yea I know it's sad but have been having this thought and I know that we have a great many brain boxes out so tell me where I could be wrong. lol and I bet it's alot of places.
Topic is the big bang and expanding of the universe.
Everyone talks constant known's i.e speed of light etc etc. I look at it this way and tell me where my logic is wrong.
In the event of an explosion, things are forced apart. The nearer you are to that force the faster you go and as that enegy and distance increase you decrease speed until you come to a near stop or another force kicks in and takes over, lets say gravity (whichever form that maybe).
Therefore would it make sense that the expanding universe is not a constant. That we would expect it to be very fast, slowing down and the increase again???
so any ideas lol
As a fellow nerd, I want to discuss, but I have to go for a glaucoma test right now.
Seek out Hubble's Law
V = Ho D
where
V is the observed velocity of the galaxy away from us, usually in km/sec
H is Hubble's "constant", in km/sec/Mpc
D is the distance to the galaxy in Mpc
Its not a problem for me to understand that. What does however puzzle me is what is the universe expanding in to ?

a bigger larger universe . why anything else universe is just a concept
think about it, during the nineties they said the universe was contracting, saw something a couple of weeks ago that it was expanding, but faster than they can figure as to what it is expanding in to ummmmm maybe we are displacing, like an iceberg does in water.

next time it contracts ,do you think it will contract far enough to vanish up its own ass :lol: :lol: :lol: :lol:
Reminds me of the movie "men in black " when the universe was carried in a ball around a cats neck .
what force makes it contract
Remember one of Newtons laws of motion that states that an object in motion will continue in motion unless some force acts upon it to slow it down. In space there is no such force No wind, no friction....nothing. hence the constant expansion theory.
what force makes it contract

I dont think it does ( contract ) was just following on and making light of words written in a previous post :smile:
Interesting concept, creation by accident...
roll shock lol grin razz
maybe we are just a cell in another body lol yea never know
You need to read Bill Bryson's book - I think it is called A Short History of Almost Everything.
He covers the universe and it is believed he makes it a bit easier to read than Stephen Hawking's book.
Anyway, one of the theories is that the universe did explode out but is now slowly being sucked in to the sun by the force of the sun's gravity.

In 1905, Mr. Einstein published his Theory of Special Relativity. In 1922, a Russian mathematician, Alexander Alexandrovich Friedman deduced from Einstein's work, that the universe must be expanding. Till then, all observations indicated that, outside the Solar system, things were static. Einstein added a constant to his equation to eliminate the inferred expansion. In 1929, Hubble showed that the universe was indeed expanding. The rate of expansion was thought to be a constant. This led to conjecture as to what started it all. They looked at a thought experiment, using the laws of motion to look back; if they reversed direction, the universe would go back to it's starting position. This appeared to be a singularity, a point. So this point must have expanded, expanded at high energy. They called this, "The Big Bang. They theorised that if it started as a point and exploded, it would move outward, rapidly at first, but that gravity would slow it down. this theory was maintaineduntil very recently, when the latest observation/calculation showed that the expansion is speeding up. This actually fits in with a theory that i have held for many years, but have been assured that the math doesn't work (my model is a visualised thought experiment, I don't have the math to check it myself) lol
The work is complicated because the expansion is not uniform, there appear to be local "attractors" pulling adjacent galaxy groups and even galaxy clusters closer to each other within the expanding universe.
The model, though, is not of an explosion, it is more of a rice pudding with currants dotted around in it. as the rice cooks, it expands and the currants move apart. if we consider a few currants in line, equally spaced apart, the distance between 1 and 3 will be twice the distance between 1 and 2. The increase in distance will also be twice as much. So the speed with which something is leaving us, is proportional to the distance between us and it.
Well that clears that up then -)
