Is Dark Energy Actually the Pull of Black Holes?

[rhyshanan]

Instead of being a force that works against gravity. Is it possible that dark energy is the pulling of everything towards the event horizon of a black hole? This would marry dark energy with gravity and replace myserious massive amount of energy with a logical source of energy/force that we know to be constant.

Matter/light closer than us to the event horizon, would be moving faster than us towards it ... which is why we wouldn't see that light ... only blackness.

Matter/light further away from the event horizon than us, we would be moving faster than and wouldn't see either.

Discuss ...

Black hole? Pulling where? Where is this black hole located? I'm confused.

That is backwards from how a black hole operates.

Thank you for your passionate responses guys ... I'm glad to see the community is as eager as me to learn and exchange theories ...

Have you ever dropped a coin in one of those big upside down icecream cone shaped shapes? ... so the coin travels round and round and round, goes faster and faster until it reaches to the center of the cone. The traveling part is the event horizen part of a black hole.

Now drop 3 coins and imagine you are the middle coin.
Look backwards and the coin behind you is moving away from you.
Look forwards and the coin in front is moving away from you.


This observation is what we observe with dark energy

But this has a specific directional bias, towards the center of the ice cream cone. If I dropped a lot more than 3 coins, I'll see that all the coins ahead of me are going towards one location (the center). As far as we know, the universe expands isotropically, without any directional biases. In other words, we are not all moving in some direction. How does your theory account for this?

I should also note that this forum has some rules against overly speculative posts, and personal pet theories. So, unless you can cite some peer reviewed references, be careful of going over speculative.

Yes the universe expands isotropically as far as we know. The coin/cone was a simplified analogy.
The theory referred more to the pull towards the event horizon than towards the center. In this case, the moving away would not only be appear from the front and back but also on the sides because the pull would happen along a circumference

 

[Chronos]

Black holes do NOT pull anything in the direction of the event horizon - unless, of course, it is outside the event horizon. Everything is pulled towards the center of the black hole.

Maybe you are thinking like this?

Based on relativity
as we observe further and more distant objects, they are receding faster
and therefore contracting in their line of motion
so that they are flattening
and so is the space between them contracting
so that as they approach the point where their recessional speed would be c
they present in effect an increase in apparent density (more objects fit in the space as we see it) and mass (energy)...

That is to say that in the last bits of distance approaching the observable limit where recession approaches c, there is increasing contraction to allow an infinite amount of paper thin and progressively thinner galaxies and clusters, etc, all very close and increasingly closer to each other approaching the boundary.
So from our perspective, the region of the boundary seems to support any infinity of contracted space full of flattened objects so as to approach infinite density at the limit.

Now that would be like a black hole inside out - the inner surface of the observable universe's recessional boundary where recession approaches c would be like the the outer surface of a normal black hole.

So you might be thinking that this shell of infinite density might act to pull the contents of the interior out toward the shell... apprearing to us in the interior to be as a universal acceleration of expansion.

But, since the shell would be spherical and symmetric, the net pull on any point inside the shell would be zero. Newton provided a nice proof of this... theorem XXX now called the "Shell Theorem". You can look at it here Newton-Principia-Book I-Section XII.

Tidal gravity from black holes is not uniform - it is attractive in some directions and repulsive in others. That's not what we observe in the universe. In addition, such a black hole with so long-ranging gravitational influence does not fit to the finite age of the universe.
