Well when its biggest advocates wins the Fields medal (a prize in maths), and had to encourage someone to invent a prize (almost...

The problem with creating theories that cannot be experimentally confirmed, is that they cannot be experimentally confirmed.

After having read Brian Greene's The Elegant Universe I have been a bit enthusiastic, but unfortunately ...

In terms of general knowledge, Newton's work is more varied; Newton wins. In physics, Newton did exceptional work despite not having...

I think Timescape is a model that says the inhomogeneity is strong enough to affect our observations, but you can model inhomogeneity as...

You can formally model the evolution of fluctuations via perturbation theory. As I understand it, the point isn't really that "voids...

Wasn't that the Timescape model?

What martinbn is trying to point out is that locally, time passes at the same rate at any point in the universe, even near an event...

The clock near the black hole slows down! Compare to what?

I have some solemn news to report. Many in the community had been wondering where the prolific @Vanadium 50 has been. V50 hasn't posted...

Yes. Not "never". Just not in the last two billion years. Inflation does cause accelerated expansion, yes. In our best current model...

Sort of. It can apply to an expanding universe that is only dark energy dominated after a certain time, but not before that. That is...

Both inflation and dark energy violate the energy conditions and refer to the accelerated expansion of the universe. Is this a...

I think the summary in Sabine Hossenfelder's new video is excellent. Many important points made, I have bolded two at the end that...

It offers a reformulation that might prove to be useful beyond foundational/conceptual questions, and there would be no problem in...
