TL;DR Dark Energy is a force that is accelerating the rate of expansion for the universe. It accounts for 72% of all matter and energy in the universe.

Where the fuck is Dark Matter I thought this was supposed to be a face off or something?

Doesnt exist.

That really puts it into perspective for me now, thanks!
Love the recent spread of scientific threads here :iia:

contest and u may win watch video for details
Damn this shit is scary
Dunnno about you guys, but I like how FP is becoming the new Slashdot. lol
I forget the article but I thought there was some theory for powering space ships with dark energy or something. I dont know I just read the headline and looked at the pictures.
It would be cool if we ever learn to manipulate dark matter and dark energy. Shit would be cash.
But something that would be even better would be to manipulate fluctuations in the quantum vacuum. You could create matter and energy out of nowhere.
I hate that everything is possible and impossible at the same time. :saddowns:
Many mixtures of physical words in incorrect terminus and even mixing up "dark matter" with "dark energy" (but by accident I suppose).
[quote][U]Dark matter[/U], or a cosmological constant just like it, was first proposed by ol' Steinie, or Albert Einstein, if you prefer formality. He created it to counteract gravity and it's pull, and create a [U]stable universe[/U]. This means that he didn't like gravity pulling the universe back together, so he [U]created dark energy[/U] to pull it apart, and create a static universe.[/quote]
Should be "dark energy" and "stationary universe". Also he "did not create or invent dark energy", he added a factor (the cosmological) constant to his field equations to make the universe static.
Later (now), a cosmological constant [b]could[/b] be one of the explanations for dark energy (but mustn't). There are many different models about it. Even dark energy causing a pseudo-force due to density inhomogeneity in the universe.

Also dark energy is not a force, it is causing the force which is responsible for accelerating the expansion. Energy =/= Force =/= Acceleration.

Dark energy is 72% of all matter AND energy. Not counting energy, dark matter is 63%. 63 sounds more impressive than 22, which is a wimpy number.
And thanks Avon, I'm not terribly good at thread making am I? I'll go fix that up.
But if I make cookies will the Universe let me live?
How do magnets work? And I don't want to talk to a scientist, they're liars.
Fucking magnets.
I'm waiting for the blokes at CERN to find out what Dark Matter and Dark Energy is, and if it actually exists.
Really loving these influx of science threads.
