Hubble’s and Lemaître’s mathematics is correct, but the physics is abominable.

He didn’t Hubble did, Einstein had trouble accepting it.

Hubble proved it but it was also in Einstein’s equations. He thought his equations should balance so he added a fudge factor. That fudge factor was the experimentally proved Hubble Constant. Without the fudge factor, the universe expands.

Einstein’s fudge factor was the Cosmological Constant, since revived as an explanation of the unexpected acceleration of the expansion of the universe. Hubble’s Constant is the current rate of expansion of the universe.

I thought that without the fudge factor the universe collapses?

Yes, possibly. It’s the same thing. Universe is expanding and depending on how fast and how much mass, it may keep expanding or reach a point and start contracting. Either way, it’s not static right now which the fudge factor was trying to artificially model.
