Welcoem to posts!!
in the future - u will be able to do some more stuff here,,,!! like pat catgirl- i mean um yeah... for now u can only see others's posts :c
Axions were introduced to the world of physics in the 1970âs, when researchers believed they might be the particles that make up dark matter. While early conceptions about axions have since been proven wrong, the particles are now making a comeback as the best motivated candidates for dark matter. Letâs find out why.

Data collected by NASAâs James Webb Space Telescope is in conflict with predictions based on the hypothesis of dark matter and instead confirmed predictions made with Modified Newtonian Dynamics, MOND. While the failure of dark matter has been widely discussed as galaxies that are âtoo bigâ or âtoo oldâ, little has been said about the success of MOND. In a paper that just appeared, we have an excellent summary of the present situation, and it doesnât look good for dark matter at all.

The idea that social media causes children mental health distress is plausible, but unfortunately it isnât true. Trouble is, if you read what the press has written about it, you wouldnât know. Scientists have described it as a âmoral panicâ that isnât backed by data, which has been promoted most prominently by one man: Jonathan Haidt.

The Kessler syndrome is a scenario where, if too many collisions occur between pieces of space debris, low earth orbit will become filled with clouds of tiny particles. All those particles floating around the planet will then make the area unusable for spacecraft and satellites. According to a new study, that scenario might unfold sooner than youâd think. Letâs take a look.

In the past few days we have seen a lot of rumours about troubles with AI scaling. In this video, I have a brief summary of recent events, who said what, and why I don't think AI will solve all of physics.

Innovation is slowing, research productivity is declining, scientific work is becoming more disruptive. In this video I summarize what we know about the problem and what possible causes have been proposed. I also explain why this matters so much to me.

Many viewers have asked for a review of a recent study which supposedly shows ânew evidenceâ in the climate change âdebate.â More specifically, the studyâs authors claim that we need to conduct more research into whether or not carbon dioxide emissions really affect climate change. Iâve had a look.

Scientists report progress in storing energy by shifting the shapes of molecules, a solution that could be directly combined with photovoltaics. This idea makes a lot of sense â at least to me. Letâs take a look.

Recently, some astrophysicists have claimed that black holes are the source of dark energy, a force that speeds up the expansion of our universe. The idea fits well together with observations that seem to show that dark energy is getting weaker.

For decades, scientists have been looking for a theory of everything, which can combine Einsteinâs theories with the standard model while also explaining all masses and interactions within the standard model. In this video I explain why I have become convinced that such a theory does not exist.
