    It appears the physics concept of absolute rotation - does rotation exist absent other bodies to rotate relative to - is controversial and debated.

    https://en.wikipedia.org/wiki/Absolute_rotation

    It can be measured by people on the surface of a rotating body like Earth - but there are other forces at work like gravity that cloud the picture.

      Came across this while reading a thread of people complaining that computer cases now come with glass instead of acrylic.

        Astronomy.

        A new ground based telescope finally went online yesterday. The Vera Rubin Telescope

          From a year ago.

          Longest time-lapse footage of an exoplanet to date assembled from real data

          Constructed from real data, the footage shows Beta Pictoris bβ€”a planet 12 times the mass of Jupiterβ€”sailing around its star in a tilted orbit. The time-lapse video condenses 17 years of footage (collected between 2003 and 2020) into 10 seconds. Within those seconds, viewers can watch the planet make about 75% of one full orbit.

          "We need another six years of data before we can see one whole orbit," said Northwestern astrophysicist Jason Wang, who led the work. "We're almost there. Patience is key."

            I believe it without seeing it. Planets orbit around stars.

            Yes, but first you have to figure out that those little anomalies you see once every 8 months is actually an orbiting planet not just random noise.

          I am slowly working my way through this video on breaks at work, so I can't comment on the last hour, but the first hour gives an excellent education on the scams and schemes and nonsense known as crypto and NFTs.

            Playing with Uranium 101



            Nuclear Physicist Galen Winsor
            I had watched that video years ago on youtube
            There's one from 11 years ago which is probably the one
            I watched. This one is was posted 2 years ago and bit better
            quality

            I suggest watching the entire video. Time permitting of course. In the meantime, watch from 0:01 to 21:38.

            Most interesting part is from 13:35 - 16:13 Pellets made from Nuclear waste used as basically a battery.

            Looks like each generation eventually finds the video

              Children who lived near a St. Louis creek polluted with radioactive atomic bomb waste from the 1940s through the 1960s were more likely to be diagnosed with cancer over their lifetimes than children who lived farther from the waterway, a new study has found.

                We now understand the effects of radioactive substances after extensive research, same with lead and mercury. Many substances currently in use remain unknown for their long-term effects. We are currently investigating PFAS pollution, which has been widely used since the 1980s and continues to be used and discharged into water and air., which can make people sick. Or the danger of all pesticides and the combination of different pesticides, which can, among other things, lead to Parkinson's disease. There is so much to research about what we have been using since the last century.
                MagnΓΊs: - I have fans of all ages and I don't think it's weird when older people like LazyTown. LazyTown appeals to people for many different reasons: dancing, acrobatics, etc.
