Does GR require dark matter to be present to hold a galaxy together? Would First Motion be an improvement?

The information I have is that GR requires dark matter to be present to explain how masses in a galaxy are held together. In First Motion, there is not such requirement because the collective...

Can Einstein's GR be replaced by a mechanical model?

When Einstein published his relativity theories, he was not yet aware of what we now call the Big Bang. That means he did not capture in GR one of the motions we are involved in. I call that...

Can RIPA or SDS lysisbuffer be used for plant cells?

Hi, I'm looking for a lysisbuffer that can make the proteins from oats available for a Bradford protein assay. RIPA and SDS are both compatible with the kit I'm planning to use (thermofisher) and...

Does Propylene-glycol influence manipulativity of specimen for museum collections?

Dear all, Propylene Glycol seems to be a promising alternative to ethanol or other more toxic trapping fluids for insects. But, I've experienced in a few trials that specimen become extremely...

Is it true that there is a physico-statistical meaning to the constant π other than circular geometry but the iron guardians of the SE deny it?

We assume that there is a physico-statistical meaning to the constant π other than circular geometry, but the iron guardians of the Schrödinger equation deny this. The iron guardians of the...
