dorlomin Posted June 23, 2020 Share Posted June 23, 2020 (edited) https://www.bbc.co.uk/news/science-environment-53151106 Possibly one of the biggest break throughs in astronomy for the decade, LIGO, the detectors that detected gravity waves seem to have used it to detect a star that is heavy enough that light does not escape like a black hole but who's matter has not yet collapsed into a singularity. The other possibility is it is a light (as in weight not radiation) black hole. Either of these objects would be novel to science and need some advancing in physics to explain. I do not think this will change our understanding of gravity but may related to the weak nuclear force and its carrier particles, the W and Z bosons. Though I will have to read up on that. My books are still all in boxes.... hmmmm. While I am here..... (actually I think its the strong force and neutron degeneracy that prevent collapse, the weak force gives in when the pressure is great enough to force electrons and protons into neutrons. ) Edited June 23, 2020 by dorlomin 1 Quote Link to comment Share on other sites More sharing options...

dorlomin Posted July 7, 2020 Share Posted July 7, 2020 (edited) Some new research out a couple of weeks ago seem to put Axions as pretty much the leading candidate for dark matter. Dark matter is something that makes up most of the "stuff" in the universe but only interacts with gravity, not the other 3 fundamental forces, electromagnetism (aka light), the strong and weak nuclear forces. Axions are a hypothetical particle that was created in the very early universe, new research suggests they may have been created in enough quantity to be most of the dark matter. This research is still very new and candidates for dark matter have been chopping and changing for decades. They solve a couple of other small problems in physics as well though and that is often a good sign they may yet be out there. https://phys.org/news/2020-06-case-axion-dark-gains-traction.html LHC is nowhere near energetic enough to create them so it will be decades before we narrow down a way of testing for them directly. The theory for them relies on what is called "quantum chromodynamic field theory", this is pretty well established as well so they are not wacky way out there particles like some that get proposed. More like when people needed things like antimatter and nutrinos to make equations work (both are now very widely accepted) Edited July 7, 2020 by dorlomin 1 Quote Link to comment Share on other sites More sharing options...

See Comet NEOWISE in the sky this month Is it visible in Aberdeen? Its pretty low and so will be in the gloaming for much of the evening. (I know its just visible this far south.) 0 Quote Link to comment Share on other sites More sharing options...

tamthebam Posted July 19, 2020 Share Posted July 19, 2020 I managed to see the comet last night- it was a bit faint but I saw it through binoculars just above a bank of cloud. It looked very comet-like i.e. a dirty iceball with a wispy tail. I also looked at Jupiter for the first time in my life. My binoculars aren't particularly powerful but I could make out the disc and the Jovan moons looked like little stars next to it. I feel inspired to have a look through a telescope now. 0 Quote Link to comment Share on other sites More sharing options...
