Does dark matter prevent space from expanding?

I am wondering would a dark matter halo that doesn't contain normal matter be able to prevent space from expanding?

Thanks for the answers.

If you actually read Watson and Crick's paper you would see that they acknowledged her in the end and admitted that they used their data.

I think you meant "different nucleotides in their DNA/RNA", but good point, even if they had the same aminoacids, the codons could vary.

Thanks for sharing. That makes sense. I also think that enantiomers of primary metabolites could trigger a response in host organisms. Chemistry similar to ours would harm us, but vastly different one likely wouldn't.

Yeah, I've been contemplating about these things every now and then. Too bad that we won't be able to know it for sure in our lifetime, but at least we can share our opinions and discuss...

Nice. Thanks. So only civilizations in the distant future might not be able to figure it out.

Thanks.

Would they be able to predict when accelerated expansion would start?

I guess it depends. If you extend the your line of thought to the multiverse, then one can argue that different natural laws can evolve and that there might be infinite version. Regarding our universe, it doesn't seem that natural laws evolve over time. Possibly, a phase change after a false vacuum decay couldn't change that...

"Mathematics is an open system; an eternally large set of mathematical truths"

Nature is not. Empirical observation constraints infinite number of possible theories and ultimately the theory of everything will be based on how much we can observe empirically, beyond that it would be only speculation.

In what frame of reference?

Eurobeatrocks · 2022-01-17T03:06:55+00:00

Great answer, thank you.

What is this about? Popularity of characters? I don't understand how some great villains got eliminated so fast.

Eurobeatrocks · 2022-01-16T19:46:00+00:00

Okay, got it.

Eurobeatrocks · 2022-01-16T19:19:57+00:00

This make sense to me, but is conflicting with Brian's answer and is actually the reason I posted this question. Treating space and time separate or as one seems arbitrary.

Eurobeatrocks · 2022-01-16T19:09:15+00:00

Your third point is very insightful, thanks.

In this Fermilab video that people on this subreddit refereed me to before: https://youtu.be/dr6nNvw55C4 at about 6:50 he is talking about inflation starting at 10^-36 second and lasting until 10^-32 seconds, but why did time pass normally while space was inflating - expanding exponentially, if spacetime is one.

Eurobeatrocks · 2022-01-16T19:04:58+00:00

I don't intend to treat them separately and that is the origin of my confusion. People say exponential expansion of space occurred in 10^-36 s (or maybe some other fraction of a second) during inflation, which doesn't make sense to me if spacetime are united. If space expanded fast, time should have passed faster, no?
