PhotoGraphicArt comments "Today in Physics" © 2026 by Neil E Clement (The Sage) depicting a photo of a white-bearded bald white man's head shot wearing a blue shirt with bluer stripes over a black t-shirt on the upper right side of a large square photo meme, looking at the viewer confidently, with a quote on the left side of the meme saying this in black and blue lettering on a white background:

“Today in Physics” for Tuesday 29 September 2026

When it is noon
GMT on January 1,
what time would it be:

on the dark side
of the moon?

in the heart of
the Hercules-Corona
Borealis Great Wall?

Ship’s chronometer would display
“time” as noon GMT on January 1
but the year would be relative.

And if the universe is truly infinite, every arrangement of matter must recur—including you, reading this, on countless Earths. The edge of space-time isn't a wall; it's a mirror. #SpaceTime #Astrophysics #Physics #Cosmology

One must first start with “nothing”
(literally “no-thing”) aka spacetime,
else there would be nowhere
to put “something”.

Gravity holography says a region of space is fully encoded on its boundary—like knowing a box's marbles from photos of its faces. Black holes #Physics #Holography #QuantumGravity #SpaceTime

Gravity bends and warps the fabric of time. Think about that for a moment. #Science #Time #Space #spacetime

Get someone else to describe the picture because I am horrible at describing things. Thanks. Planet Earth and the Moon sit on a grid which is bent because of how massive these celestial objects are. The grid represents the fabric of time. The distance between them is not to scale.

Planet Earth and the Moon are in the picture. The distance between both celestial abjects is not to scale. There is a bent grid on which they both rest on which represents how mass warps time. In the background you can see the Milky Way Galaxy and the universe.

Ask Ethan: Do white holes, the opposite of black holes, physically exist?

Black holes definitively exist, and hundreds have now been directly detected.

Mathematically, white holes are just as permissible.

So where are they?

Does the future rewrite the past? No — and that's the point. The universe stays coherent; no info outruns light or rewinds time. A century in, we still don't know what quantum mechanics means. #SpaceTime #Astrophysics #Physics #Cosmology

Maybe “forward in time” isn't a universal direction at all.

🌌🤯 Some theoretical models reveal a far stranger possibility: two futures. https://youtu.be/PQzUiBVHI4s
