Can gamma-ray bursts reveal hidden interactions between dark matter and dark energy?

Physicists combined gamma-ray burst data from Fermi with supernovae measurements to test whether dark energy and dark matter interact, a possibility proposed to solve the Hubble tension. Careful treatment of measurement uncertainties revealed that interactive dark energy models don't fit the data better than the standard model, despite having more parameters. GRBs remain useful for mapping the universe's expansion at large distances, but can't yet settle debates about dark sector interactions.
