Nima Arkani-Hamed - Why is the Quantum so Mysterious?

Particles at two places at the same time—superposition. Particles communicating instantly with no respect to distance—entanglement. How to make sense of such weirdness? Quantum mechanics is how the world works at deepest levels. But nobody has any idea why.

This has been recently posted but the video is at least 10 years old, this is why Nima looks younger and has not defied entropy like some have suggested.

No One can explain Physics better than Nima. He's a precious gift to Humanity.

It's incredible that these giants of science could not accept the consequences of their own discoveries. Plank with his particles and Einstein with his relativity.

The reason there are so many problems with QM and Cosmology, is because of mathematical equations based on ' Uncertainty Priciple ', ' Probability Theory ', and ' imaginary Numbers ', and not logic. As with just accepting that the electron, as described in the standard model, can't drop below a certain level in the atom, without any logical explanation why.

There is a logical explanation, and I can provide it in two hypotheses I have been working on regarding QM, and an alternative to the big bang theory, inflation, and the expanding universe. Kind regards,

Tony Marsh.

Another Iranian genius like Omer hayyam, Ibn-i sina, Harezmi...., respect to Iran from Turkey.

All this stuff is just flying over my head like a flock of geese.

I remember studying particle “physics” as part of my undergraduate engineering program in the late 1960s - seems so primitive now. I’m surprised we didn’t discuss why the earth was flat!!!

[mehdibaghbadran]

The experiment language & explanations, is different than science & scientific language, but they both have the same results.

My sense is that the reality of the universe is quite terrible, terrible in the sense of the mortifying, the fearsome sublime.

[jamesruscheinski]

Is there a quantum field / wave function substructure that brings physical reality in classic space from past to future?

[frhe]

Every time a particle exits the double slit experiment or the cat either dies or lives -the universe splits explaining that the universe needs to and does double in energy in a planck length e=mc2 to create matter for another timeline universe to incorporare the splintering of the origin universe.Splintered universes then become undetectable vis-a -vis many worlds interpretation of quantum mechanics

[chargersina]

It is 2023 now and Nima has changed his mind about virtual particles altogether. Doesn’t believe virtual particles exist. Also believes particles create space. Time is much more difficult to figure out.

[jamesruscheinski]

Are there any certainties in quantum, like position and velocity in classical?

[TheFrenchNanny]

Yep as I thought ... I am even more confused now about reality!

[borisbryant.]

2014 his head was balding, rotting with age, 2019 looking younger and hair is back
i don't understand this quantum this has been swapped with a silicon humanoid or
something is wrong somewhere he has come across the forbidden truth even in isolation

[lucyoriginales]

Why don’t you just say “ I have no idea”

[jamesruscheinski]

Why is it four space dimensions laterally / horizontally (front, back, left, right) and only two dimensions vertically (up, down), even when lying down?

[sacriptex]

Nima used to be bald, but now appears that a quantum fluctuation make his hair grow

[jamesruscheinski]

Almost seems like quantum mechanics on bottom side while classical mechanics on top side, similar to earth and ocean below with surface and sky above.

I thought that the electron doesn't fall into the nucleus because of it's associated wave function...
