Astronomers Activate World's First Dark Energy Space Camera

in before "camera is digital and therefore inferior".
oh wait, this is not imdb.

This i all well and good but doesnt relaly tell us anything.
My theory is that universe is accelerating because the "big bang" is still happening, ie we are still "Exploding" just slower than before.

I find it odd that scientists are surprised matter is accelerating. I mean isnt space 101 that if you apply force to matter it will keep accelerating unless it runs into soemthing or you apply enough force to slow, stop or change its direction?

Therefore if the big bang happened, then it makes perfect sense that the matter from that event would have been given a "push" away from the source and would continue to accellerate accordingly.

Certainly within for example galaxies there will be local events that move matter in other directions, but the original galaxy itself will continue to display the original force influence no?

In any case its very interesting and a great time to be alive when we are unlocking so much of our foundations and origins.

Actually, given there are no forces acting against it, a body will move at constant velocity when a force is applied to it. To make it keep on accelerating, you would need a constant force. The Big Bang happened only once, so logic dictates that after the initial acceleration, the galaxies would continue to move away from each other at a constant velocity, and actually decelerate because of the gravitational attraction to each other. But something keeps providing the energy to keep up the acceleration.

I love physics. I really really do.

 

[weirdee]

ooh, can we somehow perhaps harness this mysterious source of energy? or is it the kind of thing that calls forth the deep ones...

that's not quite right. as the first law of newton says:"If an object experiences no net force, then its velocity is constant: the object is either at rest (if its velocity is zero), or it moves in a straight line with constant speed (if its velocity is nonzero)."(god bless Wikipedia!) so we had a net force at the beginning and the big bang and now there is no force. so we shouldn't have accelerating unless something else cause that force. thats why most scientists were mind blown when they found out the universe is expanding.

I love you science, you're so wonderful to us.

Was thinking this.

Oh if only I were less lazy, I would be moar attentive to your findings >_>
