Same old, same old: give the points and bet on Big Al.

Makes the case that we would have rather quickly developed all of Big Al's massive achievements without him. Convincing up until general relativity. When you read about what it took him to come up with that, I think it would have been many decades--if ever--before anyone else would have gotten it.

As usual, give the points and bet on Big Al.

An argument that there are some significant gaps in modern cosmology.

Much easier said than done, of course. But if you'd like to try, here's some potentially useful discussion.

Readers of this blog know the drill by now: give the points and bet on Big Al.

If you believe that Einstein’s theory is incomplete, then it behooves you to carry out new and ever more precise experiments and observations that may point to additional anomalies and reveal the path forward. This is extremely hard because Einstein’s theory has already been tested to incredible precision over the past half-century using laboratory experiments, measurements of planetary and spacecraft orbits in the Solar System, and observations of pulsars in double-star orbits. Therefore, finding new ways to test the theory is very hard, and coming up with extensions of the theory that predict new observable effects but are not ruled out by previous observations is even harder.

You know the drill: when in doubt, bet on Big Al and give the points.

How Big Al viewed God.

A ringing statement that physics isn't "dead" and that there's a lot more to find out. (I checked: the spirit of Big Al approves.)

Sabine Hossenfelder is pretty excited about a new paper on warp drives.

Once again, the weirdness of modern astrophysics:

That realization, on its own, seems like a remarkable coincidence, raising the question of whether our Universe might actually somehow be the interior of a black hole.
