Why is our universe expanding and why is our solar system heating up?

If you just shut off gravity and had no dark energy there would be no acceleration.

That could be an incorrect presumption. If you 'shut of gravity' and consider that space is 'expanding' then the areas that have expanded expand again (and so on). This to an observer appears as acceleration.

See the link I posted earlier...

Space is expanding because something is driving the expansion. This driving mechanism is dark energy. If you say there is no dark energy, then there isn't any other explanation for the expansion.

I did read the link. It's some single person's hypothesis which he fully admits hasn't had a full theoretical treatment performed to see if it could really work. There's no peer-reviewed paper, actually there's no paper at all.

This driving mechanism is dark energy.

My original point is, that is a theory, not a fact. However, it's being used here as a fact.

You act like 'some single person' is an ATOT poster when it's a researcher at CERN...

Take a look at the WMAP papers. The energy density of dark energy has been measured. We can see its effects both on the dynamics of galaxies now as well as the CMB anisotropies.

And this single researcher at CERN had someone at Harvard say it's very unlikely he's right. And this single researcher at CERN hasn't even gone through the numbers of his own theory yet. That makes his idea just that, an idea. Putting it up against what is currently known in cosmology and making current experimentally supported theory seem like a wishy-washy conjecture won't convince anybody.

In order to get anyone onboard with this idea you need:

1. A peer-reviewed theoretical paper.
2. Experimental data supporting the paper.
3. Experimental data showing some flaw with the current theory.
4. Experimental data confirming a prediction of the new theory.

Right now the guy is stuck at 0. The competition is at 4.
