Latest James Webb data hints at new physics in Universe’s expansion

Earlier this year, JWST researchers reported on measurements built on last year’s confirmation based on Webb data that Hubble’s measurements of the expansion rate were accurate, at least for the first few “rungs” of the “cosmic distance ladder.” But there was still the possibility of as-yet-undetected errors that might increase the deeper (and hence further […]

Supermassive black hole binary emits unexpected flares

“In addition to stars, gas clouds can also be disrupted by SMBHs and their binaries,” they said in the same study. “The key difference is that the clouds can be comparable to or even larger than the binary separation, unlike stars, which are always much smaller. “ Looking at the results of a previous study […]
