New "theory of everything" could finally make 'quantum gravity' a reality — and prove #Einstein wrong
The proposed theory grapples with the fact that #quantummechanics (basically modern #physics) and #generalrelativity (#Einstein's theory of gravity) both describe the universe perfectly, but are mathematically incompatible with each other.

We are all moving ....but we don't know it.

""Every man and every woman is a star." That is to
say, every human being is intrinsically an independent
individual with his own proper character and proper motion"

It's only when we move against our free motion that we feel force on us. Gravity is not a force.. it's the covariant derivative of our world lines on spacetime.

Aleister Crowley said it first.

`The present work aims at deriving the gauge theory of gravity using compact, finite-dimensional symmetries in a way that resembles the formulation of the fundamental interactions of the Standard Model... unified gravity can provide the basis for a complete, renormalizable theory of quantum gravity.`

Unifying general relativity and the electromagnetic force? (I presume this also includes the weak nuclear force at sufficiently high energies, but this summary doesn't say)

https://phys.org/news/2025-04-einstein-field-theory.html

I'm pretty much at the limit of my understanding of field theories and such just in this summary article, I don't think I'll even try their full journal article.

@cenobyte - Does Professor Skye or her research assistant have any comment on the matter?

Fresh from the @j824h_arXiv_astro_ph : calculating (numerically) the impact of a wave hitting a spherical overdensity in the cosmos, the wave suffers from a Shapiro delay and thus shows interference patterns. So do we really need fuzzy dark matter to observe interference?! https://arxiv.org/abs/2504.08286

Whooooaaaa! The new #JWST image is so good! So much physics going on — physics Einstein himself thought about!

This is called an Einstein Ring. When a massive foreground galaxy (in this case, an elliptical galaxy) warps the space-time around it, light from behind it bends in our direction.

The JWST caught this fantastic example, where the background spiral galaxy is getting warped into our view. It appears as a ring, but we can see its structures like its spiral arms, gas features and star clusters.

Incredible science happening here!

Today I learned that the person that proved the equations of general relativity (for empty space) always have well defined solutions was a french lady who died about three weeks ago.

Dr Yvonne Choquet-Bruhat proved this via results published in 1952 and 1969: https://en.wikipedia.org/wiki/Yvonne_Choquet-Bruhat #historyofscience #generalrelativity

`In general relativity, a white hole is a hypothetical region of spacetime and singularity that cannot be entered from the outside, although energy-matter, light and information can escape from it. In this sense, it is the reverse of a black hole, from which energy-matter, light and information cannot escape. `

Here are some very sad news on an already sad day!
https://www.ihes.fr/en/yvonne-choquet-bruhat-eng/
Yvonne Choquet-Bruhat died yesterday at the age of 101. May she be united with Einstein again and the two can complete the GR-work that they had!
For everyone who wants to enjoy one of her works, have a look at this introduction to General Relativity: https://library.oapen.org/handle/20.500.12657/85657

#DavidLynch consistent with his other worldly oddness par excellence , the last strip above contains one of the few examples I know of of a #GeneralRelativity joke.

Can any astrophysicist here tell me whether the blue ring in Webb's image of quasar RX J1131-1231 is also coming from the quasar, or whether it's coming from the lensing galaxy in the centre? I'm reading contradictory information about this on the ESA site
