The 5 greatest puzzles in fundamental physics
bigthink.com/ ^ | Ethan Siegel

Posted on 10/04/2022 6:19:13 AM PDT by BenLurkin

1.) How did the Universe begin?

What “type” of inflation occurred? What preceded and/or caused inflation?

2.) What explains neutrino mass?

Are neutrinos Dirac or Majorana particles? Are there heavy, sterile neutrino species?

3.) Why is our Universe matter-dominated?

More matter than antimatter permeates the Universe.

4.) What is dark matter?

Its effects are understood, not its underlying cause.

5.) What is dark energy?

Its properties indicate a constant, positive spatial energy density.

“Is the inability to answer these (AND OTHER) questions the reason the whole physics establishment has gone ga-ga over the quantum thingy?”

No, Quantum Mechanics was discovered in the 1920s before any of these issues were known.

6.) Why is Xao Biden President of the United States?

The election was stolen by the Deep State.

They left out the biggest puzzle of all: what is the mechanism underpinning Quantum Entanglement?

Interesting explanation; thanks for laying it out.

But that then begs the question ‘What does dark energy interact with?’ Nuthin?

“‘What does dark energy interact with?’ Nuthin?”

Pretty much, as Dark Energy is the expansion of the nothing between galaxies.

Dark matter is real and is looking to have a simple explanation. We can do experiments to learn about it, and have been steadily making progress

Dark Energy remains a complete mystery. There are no good theories. No ides or experiments to learn more.

Bare with me...

1.) How did the Universe begin?

God

2.) What explains neutrino mass?

Quantum mechanics

3.) Why is our Universe matter-dominated?

No matter no universe.

4.) What is dark matter?

Something you can’t see through.

5.) What is dark energy?

Come on man. You didn’t think I had the answer to all of them, did you?

“They left out the biggest puzzle of all: what is the mechanism underpinning Quantum Entanglement?”

Back long ago when I was studying quantum mechanics we were taught that none of it made any intuitive sense, but that the math worked and we just had to accept it.

The exciting work that got the Nobel today helps reframe quantum mechanics as a branch of information theory. If you think of the universe as a computer then quantum mechanics is the simplest way for it to be coded.

Entanglement is the simple idea that everything can be left undefined until needed. Only when a particle is observed does its exact nature need to be generated.

Einstein ‘inferred’ the lambda, to make his equations work out. Turns out he guessed correctly?

I suspect one of two possibilities for dark matter. The first is neutrinos that have slowed down and orbit with everything else. The other is that our three dimensional universe is stacked with other three dimensional universes in a larger dimensional superverse. Only gravity reach’s between between them which is why it is so weak compared to the other forces.
