Current Events > What do you think dark matter and dark energy are?

(+) Yeah! (+)

They make up the majority of matter in the universe. But what are they? The suspense is killing me.

It's the stuff that lets Heimdall summon the Bifrost.

the most alpha forms of energy

I'm still in the primordial black hole camp for dark matter but don't know enough to guess at dark energy.

Dark Energy is probably gravity from a bubble universe close enough to ours to impart the force, but farther away than our cosmic horizon.

What's kind of funny and weird is that one solution for Dark Energy is that the Copernicus Principle (that Earth is not the center of the universe) is actually wrong.

If the Earth really was the center of the universe, Hubble's Law would make sense logically without further explanation.

It's the stuff you put in your ship to use your hyper drive to system warp.

I think that the laws of physics are different in the greater universal scale, just how they are different on the quantum level, and dark matter/energy is just us trying to make it fit with our incompatible physics system.

This is really just arguing semantics I guess, but if a separate universe can cause observable effects and interaction upon another, can it really be considered a different universe?

Hard to say. If FTL travel isn't possible, there's really no way to actually get there so it shouldn't have a visible effect. Still has gravity though.

Trying to picture this...

So the increased expansion of space between galaxies is do to another universe alongside our own. It's gravity is effecting us but is only detectable when observing the largest structures like galactic clusters. Wouldn't those clusters all travel the same direction? Unless the gravity is acting like an actual bubble with the clusters sitting on top and sliding down the sides. That would account for the increased acceleration away from one another.

What if we got giant galactic clusters all around us, that pulls us in all different directions?

I dont know but it sounds pretty racist

I think we'd see a common direction among groups of galaxies/clusters/superclusters if that were the case. And IIRC dark energy is space itself not only expanding but accelerating. Awfully hard to explain that behavior with another object's gravity if that object is in the same 3d space.

That or gravity exists in more than the four perceptible dimensions, so we can't actually perceive dark matter / dark energy.

why? it's not a negative thing. it's probably the key to unlocking our next level of civilization and becoming masters of space
