How many levels are there in the universe?

Say the universe itself is a level.

The next level down appears to be filaments of galaxies.

Then clusters of galaxies.

Then galaxies.

Next level down again is stars.

Next level down again is atomic particles.

Then sub atomic particles.

Then quarks.

Next level down again neutrinos.

Around 10 realms or levels?

We have no way of knowing how many levels there are above the largest scale level that we can see.

Fair enough. We can certainly add many other levels between those, but no real need.

ok, so without evidence any postulated levels are speculation.

(shrugs) you can break this into smaller steps for sure. Fuck, you go straight for stars down to atomic particles? What about planets, continents, biomes, local ecosystems, animals, organs, cells, organelles, molecules?

Eg. I could start:

• Lower dimensional banes swimming in 11 dimensional M theory space.
• Quantum multiverse
• Eternal inflation multiverse
• Universe (= local inflationary bubble)
• Visible universe
• Superclusters
• Galaxy clusters
• Galaxy filaments
• Local groups
• Galaxies

Here’s one way to think about scale..

Well, size of a black hole singularity is the planck length of about 10^-35 metres.

How many have you measured?

maybe Moll is referring to the fact that GR breaks down at the Planck scale.

I saw a Tau Neutrino there! :)

Yes and no. It comes from string theory, in the absence of those large extra dimensions that appear in some versions of string theory. Some of those large extra dimensions versions have been ruled out by the LHC already.
