Sabine Hossenfelder explains why antimatter doesn’t fall up

Hossenfelder: Inside a neutron and proton there aren’t just three quarks. There’s really a soup of particles that holds the quarks together, and some of the particles in the soup are anti-particles. Why don’t those anti-particles annihilate? They do. They are created and annihilate all the time. We therefore call them “virtual particles.” But they still make a substantial contribution to the gravitational mass of neutrons and protons.

Sabine Hossenfelder tackles pseudoscience — in a realistic way

Hossenfelder: “And some crazy ideas in the end turn out to be correct.” Yes, and it could be worse than that. Given the complexity of life, there should be no surprise if dimwits played by fanatics and grifters – Establishment or otherwise – are fronting poorly supported ideas and trying to stamp out more correct ideas as “pseudoscience” because the poorly supported ideas are convenient, comforting, and profitable. Anyone who doubts that factor either hasn’t been around long or has not been paying attention.

If dark energy is “neither particle nor field,” what is it?

Siegel: “It is time to take seriously the idea that dark energy might simply be a property inherent to the very fabric of space. Until we learn how to calculate the zero-point energy of empty space itself, or gain some bizarre, surprising, and unanticipated evidence, this will remain one of the biggest existential questions in all the universe.” So this is existentialism for physicists, right? Even Sabine Hossenfelder sounds sort of existential on this one.

Sabine Hossenfelder despairs over vacuum energy. Rob Sheldon responds

These specialty controversies are an interesting backdrop to the current war on math. Sabine Hossenfelder and Rob Sheldon would likely agree that 2 + 2 = 4. But survey the vast degreed hordes for whom such a statement is an instance of white supremacy and colonialism and we will see the real problem facing our civilization: Far too many people have degrees (and grievances!) but no insight into what knowledge is.
