Is Dark Energy A Force?

If Dark Energy is accelerating the Earth, sun, moon and stars at the same rate of acceleration despite the difference in masses, then presumably it can't be a force, in the same way that gravity isn't a force.

Dark energy causes a force. I think.

We don't know how the interaction of Dark Energy and our 'normal' energy/mass/whatever occurs.  Therefore,  it can be anything we need it to be.

Hmmmmm I think it still works

No, we know how gravity works.

No, we know how gravity works.

Really? Did they find a gravitron while I was at work?

What does that have to do with gravity?   


You are right, though, the Gravitrons are becoming more and more rare every year.  Finding one is becoming quite difficult.

And what does that have to do with gravity?

We might know that mass bends spacetime, but we don't know how.

What does that have to do with anything?

Well, you said you knew how gravity works

Right.  I know exactly how gravity works.

How does it work then?

It is a fictitious force that arises due to the transformation of a non inertial frame of reference into an inertial one.

Hmmm. What does inertial mean?

I don't get how mass causes attraction though, it doesn't make sense to me.

Hmmm. What does inertial mean?

A frame that is not accelerating.

Hmmm. What does non inertial mean?

A frame that is not...inertial.

Hmmm. What does inertial mean again? I wasn't listening the first time.

Go back and read it. Don't be stupid.

I can't help being stupid 

I do believe you can. Being the wizard of Oz I can indeed say you had the brains all along.

I can feel my brain kicking in again. Woooo!

TheTerror can't help it...

Doctor Robot-Ham, if you please.

Back to business -

If Dark Energy isn't a force, then presumbly the only other way it could accelerate the Earth is by some kind of expanding wave of curvy spacetime which always pushes the Earth upwards. Only problem is, such a wave would accelerate all matter, not just the Earth but also everything and everyone on it. As a result the gravity effect wouldn't exist and we'd all be floating around.
