Very nice!
I remember reading about Galileo and his work, and he himself used this method to study the Sun spots.
Yea, I've got 1600's technology up in here!
Hey, so its been several months now and you said you were going to show a free momentum experiment using pendulums. When can we expect it to be shown?
Try asking the question again, this time without the lying or deceptive false premises.
Have you watched the one by Dispar's Lab? I think your free momentum is clearly visible there if you pay attention.
I have so many free momentum experiments by now, i guess i have become a master at engineering them 😂 @@Leksa135
If sunspots are due to reduced convection, then the sunspot should have a more stable surface, or slower fluid turn over motion. Is this observed ?
From the perspective of a atom in the sun can you explain why magnetic field prevent hot gas from rising ?
While sunspots do still move and change over time, it's a significantly longer timescale than the convective motion around it (ruclips.net/video/icjym2uEs5Q/видео.html for a video).
For how the Sun's magnetic fields affect solar weather, I've got a video here that goes into a bit of detail ( ruclips.net/video/m3eWyxyEM1g/видео.html ) but briefly, charge particles don't typically like to cross magnetic field lines (they will spiral around and along the magnetic field lines). So it's not really that the magnetic fields prevent the hot gas from rising, but that in order for convection to happen, the hot gases that have risen up need to move to the side and sink back down so new hot gas can replace it. The magnetic fields going into the Sun's surface impede that "move to the side" part (charged particles don't like crossing magnetic field lines), so it can't get out of the way for new hot material to replace it.
@@PhysicistMichaelI still don't understand what stopping the cold gas from falling, even if gas can't move to the side , it should fall into the sunspot itself. From my perspective it looks like cold gas levitating.
I couldn't see if convection in sun spot was slower , but I did notice lines of hot gas seemingly moving inwards, which is strange because why are there lines in the first place. Maybe that is where the sunpot cold gas is falling , but it falling in lines which suggest a laminar flow. The stream of hot gas seems to be moving inwards .
Question are sunspots always a specific temperature, do the have range of temperature?
What happens when sunspots collide?
