Astronomers have detected fast radio bursts (FRBs) from an ancient "dead" elliptical galaxy 2 billion light-years away, challenging existing theories.

FRBs are typically linked to young, energy-rich stars in star-forming galaxies, but this dormant galaxy contains only old stars.

The bursts, named FRB 20240209A, were identified using the CHIME telescope and pinpointed with the Gemini North telescope.

Researchers suggest the bursts may originate from merging neutron stars.

This discovery could deepen understanding of distant galaxies and the universe’s structure.

Googled what a "dormant galaxy" is and found this: Dead from the dawn of time: James Webb telescope unveils oldest known dormant galaxy

Seeing more and more challenging existing theories lately, the cracks in our theories begin to show. Which is a good thing.

Science!

Having more information always shows that existing theories and assumptions have exceptions or more complexity that we just had not come across yet.

A pet peeve of mine.

We have had consensus for a while that gravity is caused by the bending of spacetime.

Fundamental forces are named that way because we can no longer explain them as being caused by something else.

Gravity and not spacetime is still considered a fundamental force.

Gravity doesn't care what a fundamental force is, or who considers it to be one. It just exists. The labels humans put on such things are entirely arbitrary.
