Collapsing Sheets of Spacetime Could Explain Dark Matter and Why Universe 'Hums'

Isn't the hypothesis that dark matter is composed of primordial black holes quite old and established.

The attributes "old" and "established" do not describe the accuracy of a thing.

Humans believed that the earth was flat for thousands of years in various cultures - old, established, and wrong.

The geocentric model of the cosmos prevailed for about fourteen centuries until the emergence of heliocentric theories - old, established, and again, wrong.

To be clear, I'm not arguing one way or the other about the accuracy of the hypothesis you mentioned, but simply that the age and popularity of any hypothesis has little to do with whether or not it will eventually be disproven.

Earlier quoted context omitted.

If space is “empty”, then how come we can measure the temperature of the microwave background radiation? Think about it…any direction we point an apparatus, we will get a reading — the static of a radio IS the CMB, and if you could take that radio into space, and have the ability to travel anywhere, that radio would still have static. As such, space cannot be “empty”, it’s filled with photons, electrons, and quarks,…

> how come we can measure the temperature of the microwave background radiation Because that's the average temperature over an region not the temperature of a finite point. It's kind of like pressure; it really only makes sense at a macro level where you are averaging over a volume or region. The pressure at a singular finite point will also be zero because that singular infinitely small point will likely be in the e…
