Newmark's Door

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.

I expected to read about wormholes and maybe other exotica. Instead I found a discussion of mostly more conventional means of travel and no discussion at all of how those methods would get around Big Al's limit (nothing can travel faster than the speed of light).

Apparently, even some of Big Al's unpublished work was amazing.

Includes a couple of pictures I had not seen before of Big Al playing the violin.

They keep going after Big Al, but somewhere, I imagine, Big Al is saying "Bring it on."
