Because the half life is the time taken for half (50%) of the atoms to decay. But to get there you have to go through 99% remaining, 98% remaining, 97% remaining and so on. Once you got two points, you can calculate how long it takes for 50% to remain (the half life). So, there may not be enough time to go from how much there is now to be reduced to 50%, but it does have a half life.Quote:

The math works, and we can make predictions . But it could just as easily be 42.5% dark matter an 42.5% of "what's the matter for you" LOL . Or our calculations of the visible matter are embarrassingly off.
And even if 85% of the universe is composed of Dark Matter what is to say that Black Holes do not consume dark Matter? They might like it, They might like it alot.
Then there is the Quantum Entanglement issue
I am willing to bet you a million dollars the Universe will end the way I said it will. If it does not you should come and find me. LOL

"Well you see, Norm, it's like this...A herd of buffalo can only move as fast as the slowest buffalo. And when the herd is hunted, it is the slowest and weakest ones at the back that are killed first. This natural selection is good for the herd as a whole, because the general speed and health of the whole group keeps improving by the regular killing of the weakest members. In much the same way, the human brain can only operate as fast as the slowest brain cells. Now, as we know, excessive intake of alcohol kills brain cells. But naturally, it attacks the slowest and weakest brain cells first. In this way, regular consumption of beer eliminates the weaker brain cells, making the brain a faster and more efficient machine. And that, Norm, is why you always feel smarter after a few beers."

These would be horizontal, not vertical.
Yep, flashing is above the step.
That's a clever lock if the green shirt is holding onto grips.

Just read that the universe is calculated to be 1,000.......... add 24 zeros here, times bigger than the observable universe.
Which equates to the difference between the observable universe and an...... atom.
Just don't quote me on that. :)
Saw a BBC Horizon doco a few years ago that, using triangulation, calculated that the universe is flat and infinite.
Either way, interesting shit. :)
No, this is not so, not least because the universe is currently expanding at an ever increasing rate, some 12 billion years after its creation, and the subsequent creation of neutron stars inevitably involves the birth of new galaxies.Quote:

The continual creation of galaxies from the crucible of supernova would however suggest that the universe is self perpetuating and taking the continuing expansion of it also into account, I think the assumption is that there will never be an end.
The truly worrying aspect of man's position in the cosmos is the not entirely insignificant fact he shares 50% of his DNA with a fucking banana.
My recollection from my various cosmology video course learnings is that the actual universe is 46 billion light years in radius whereas the observable universe is 13.7 billion light years in radius (13.7 billion years being the age of the universe).Quote:

The expansion rate is not linked to the amount of mass existing. As long as you don't assume new matter is added to the universe that resource is limited and will be consumed one day. Presently we still have a lot of hydrogen that can form new stars, but that will not go on forever.Quote:

I guess that's where acceleration comes in. But how can the inflation be faster than the speed of light where the speed of light is the speed limit? And where Newton's First Law of Motion states that a body at rest will remain at rest unless an outside force acts on it, and all the energy was introduced in the universe at the big bang, where did the extra energy come from to accelerate it ? I would think that as that energy is converted to matter, some of that initial energy is sequestered in the matter and the universe should be decelerating .
