Where is physics going? | Sabine Hossenfelder, Bjørn Ekeberg and Sam Henry
00:00 Introduction
02:43 Sam Henry | Recent experiemental data suggest physics beyond
05:35 Sabine Hossenfelder | Phycisists need to change to move forward
09:41 Sam Henry | Cosmology has become path-dependent
12:21 Why had progress in the foundations of physics stalled?
22:16 Are the failures to find conclusive evidence a cause for panic?
37:29 Would changing the Standard Model have wider implications?
Since the 1970s we have understood the world through the lens of the Standard Model and its account of the forces and particles that make up the universe. The theory correctly predicted the discovery of quarks, force particles and most recently the Higgs boson. But a series of deep puzzles have emerged. The theory does not explain gravity, dark energy or dark matter. The quest for supersymmetry and a theory of everything to simplify the Standard Model's random complexity has failed. And now, even more ...

Anyone who missed this Speilberg film made 24 years ago MUST see this film which is much more relevant now than it was then. - JW
David, an artificial kid which is the first to have real feelings, especially a never-ending love for his "mother", Monica. Monica is the woman who adopted him as a substitute for her real son, who remains in cryo-stasis, stricken by an incurable disease. David is living happily with Monica and her husband, but when their real son returns home after a cure is discovered, his life changes dramatically.

Can't re-watch it again
I was 13-14 when I watched this movie. It's a long movie if I recall it correctly. I was so moved by it's theme, so I watched it all. I had strong feelings of sadness and sympathy towards little robot David that wanted to be a real child and to have a mom to love him. And that little bear ... I cried during some scenes. I don't ...
The Mass of Nows:
A Temporal Foundation for Inertia and Gravity

For a century, physics has lived with a quiet asymmetry. Special relativity shattered absolute simultaneity, forcing us to accept that "now" is observer-dependent—an infinite stack of "now-slices" foliating the four-dimensional block universe.
Yet when we turned to dynamics, to the origin of mass and force, we continued to treat space and time as a smooth, empty stage on which particles play. Inertia and gravity were described with exquisite mathematics, but their common cause remained mysterious. The equivalence principle told us they feel the same, but never why they are the same.
The Mass of Nows proposes a simple, radical answer: the stage is not empty. Between the infinite now-slices lies a dense plenum—the zero-point fields of every possible now, permeated by the four-dimensional extent of every particle's wave function.
Mass is not a property particles possess; it is the ...
