I was aroused by some sections of that pic
I’m guessing this one?:[INDENT][align=right]
Your sig confirms it.[/align][/INDENT]
i’ll take a wild guess and say another sex scene mixed in with violence and murder
clash of civilizations with the ultimate detonation of all nuclear arsenal, then blackness…and peace
No actually, that one was just creepy, I didn’t even notice it, and leave MJ alone :[
How is one creepy, when you hadn’t even noticed it?
Death… BY SNOO-SNOO!
well humans were bound to become extinct with the heat death of the universe in 100 billion years. i dont see all the hoopla just because we might go extinct a little bit before then
- There will be no heat death. Current theories indicate that the universe is geometrically flat and therefore will continue to expand at an ever decreasing rate, eventually becoming a cohesive whole (all values at zero, as opposed to infinite at the big bang).
- 100 billions years is a bit much.
wikipedia says it can happen and it happened in futurama. I trust them.
That’s because neither Wikipedia nor Futurama were aware of Heisenberg’s constant.
also this
my summary of this i wrote for another thread in this section:
Thanks to Einstein we know that matter and energy cause space to curve. According to his equations, the curvature of space is relative to the energy-momentum inside it (curvature = energy-momentum)
This, however, posed a problem: gravity (i.e. energy) should cause galaxies to contract, which is contrary to observation. This led Einstein to add the cosmological term to the equation (curvature+cosmological term = energy-momentum), which was a very small force that would not be noticeable to us, but that would build up over distance so it’s strong enough to hold galaxies apart, resulting in the universe that was then thought to be static.
Later, Hubble confirmed beyond doubt that the universe is in fact expanding, and not static. He also discovered that other galaxies are moving away from us, relative to their distance to us. The further a galaxy is, the faster it moves away. This means that the universe is expanding uniformally in all directions and enables us to calculate the size of the universe, how fast it is expanding, and how old it is.
Now we are posed with a new question: is there enough gravity to slow down and reverse expansion?
After these discoveries, Einstein dropped the cosmological constant, calling it his biggest blunder. However, it turns out that there is in fact a cosmological constant, but in a different way and for different reasons: curvature = energy-moment + cosmological constant.
The constant is the energy needed for the universe to expand, and apparently it comes from empty space. That may sound like nonsense, but it’s actually completely reasonable in quantum mechanics.
Virtual particles pop in and out of existence on a timescale so short that they can’t be measured directly, but their effects can be measured indirectly. Most of the mass or energy of a proton comes from these virtual particles.
It was then concluded that the energy of empty space is 10^120 times the energy of all matter in the universe, which is an incredibly bad prediction, because in order for us to exist they must be roughly equal.
The number is much too high to cancel out somehow, so it must be zero, which is only possible if there is a fundamental symmetry in nature. Theorists knew this, but there was no evidence for it and observation didn’t agree with it.
In order to solve this problem, scientists had to measure the energy of the universe, using gravity. That way we could know what kind of universe we live in:
-A closed universe would eventually stop expanding and then start contracting.
-An open universe would expand forever.
-In a flat universe expansion would slow down, but never quite stop. It’s also the boundary between an open and a closed universe.
After ‘weighing’ the universe, it was concluded that the weight between galaxies was fifty times greater than the weight of galaxies themselves, which means that most of the mass in the universe is dark, and therefore called dark matter, a new elementary particle that’s present everywhere, but has not yet been observed.
So now we know the weight of the universe. In order to determine what kind of universe we live in, we have to compare the density of matter to the density of matter in a flat universe (matter density/matter density for a flat universe), expressed as Ω. If Ω > 1, our universe is closed. If Ω < 1, we live in an open universe. If Ω = 1, we live in a flat universe.
According to observation, Ω = ~.30, which would mean we live in an open universe.
Another way to find out what kind of universe we live in is to measure the curvature of the universe:
-In an open universe, light would be curved by .5°, and objects would appear smaller.
-In a flat universe, light would be curved by 1°, and objects would appear at their real size.
-In a closed universe, light would be curved by 2°, and objects would appear bigger.
Observation tells us that light coming from distant galaxies is curved by 1°. We know this with 1% accuracy, which is incredibly good. In other words, we know for a fact that our universe is flat.
This begs the question of where the remaining 70% of the energy needed for a flat universe is (the Ω ratio): it must be in empty space, which means there is a cosmological constant, which is a repulsive force. All of this fits perfectly with observations.
To sum up, we know today that our universe is flat. That means that its expansion will gradually slow down, but never stop, and that it came about out of nothing, through quantum mechanics. We also know that the matter in the observable universe is only a fraction of the matter in the entire universe, which only 30% of everything in the entire universe.
Nuclear War. /thread
tl;dr
thank you for that insightful comment
video’s pretty interesting though
np man
lmaooooo i didnt realize one sarcastic comment would spark such intellectual discussions on the internets.
BMS Forums: Deleting ignorance…one theory at a time.
P.S while we are at it… we should talk about why Aperture Science didn’t create endless renewable energy with their portal technology:
Because they don’t want to share portal technology.
they dont have to share they can just export their electricity…then again they have high power requirements by themselves
if teleportation like that is possible then I think you just accidentally the second law of thermodynamics. But I am sure there is another energy involved.
