So this is a great explanation and I love it. But I have a request. I get how entropy works, but I’m having trouble imagining the scenario where all the molecitles end up in a corner of the room. I understand that it’s a one in a huge number probability. I get that. I’m just having trouble even understanding how such a scenario could even happen, I mean the scenario leading up to it. It occurs to me that it would be easier for me to imagine if I saw one of these reverse videos where you ran a simulation where you started all the particles in one corner of the “room” with different velocities and then take a simulation, but then ran it backwards to show how it could conceivably happen. Do you think you would do that please?

Black holes are based on a mathematical misconception. General Relativity predicts dilation, not singularities. In the 1939 journal "Annals of Mathematics" Einstein wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of G.R. predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". Time dilation is just one aspect of dilation, it's not just time that gets dilated. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. There is no singularity at the center of our galaxy. It can be inferred mathematically that dilation is occurring there. This means that there is no valid XYZ coordinate that we can attribute to it, you can't point your finger at something that is smeared through spacetime. More precisely, everywhere you point is equally valid. In other words that mass is all around us. This is the explanation for galaxy rotation curves/dark matter. The "missing mass" is dilated mass. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has recently been confirmed in 6 very low mass galaxies including NGC 1052-DF2 and DF4 to have no dark matter. There can only be clarity in astronomy if the concept of singularities is discarded. Einstein is known to have repeatedly said that they cannot exist. Nobody believed in them when he was alive including Planck, Bohr, Dirac, Schrodinger, Heisenberg, Feynman etc.

One quibble, not that you'll actually see this comment since over 9300 people have responded, but at the end of your video you said that the Milankovitch Cycles have been affecting climate here on earth for hundreds of thousands of years...

@ItsJustAstronomical 15 днів тому
You're in luck because I read every comment. I might quibble with your quibble. I said they've been important for hundreds of thousands of years. But remember the cycle depends on ice. It's unusual for the Earth to have polar ice caps. It only happens during ice ages. The Earth has been in an ice age the past few million years, but before that there were no polar ice caps and the Milankovitch cycles had little impact on the climate.

@@ItsJustAstronomical Oh wow, you *DID* respond. Nice! But I think that even in greenhouse earth mode they play a role in climate. In ice age earth mode, like we're in now, they force climate to cycle from glacial to interglacial, but in greenhouse earth mode they also result in long periods of much warmer summers/much shorter winters to warmer summers/regular length winters.

But Water is by far the greatest greenhouse gas and when water and carbon dioxide are present together, carbon dioxide only absorbs 5% of the infrared energy. Water vapour is mainly responsible for our climate and the sun is largely responsible for changes in energy. From 1880 to 1950 the temperature rose by 0.45 degrees but the increase in CO2 was only 18ppm. The CO2 increase was not nearly enough to provide this warming.

Why does the sun have a centrifugal force on spacetime? I understand the first gravity well visualized directly around the sun, and then as you leave that well you reach a peak where the sun loses its influence right? Or some sort of peak. But then after that peak another? gravity well? bends spacetime around the sun again. Why are there two wells? I don't understand why the first gravity well doesn't lead to a peak, as it does, and then immediately flatten out back to flat spacetime again
@ItsJustAstronomical
@ItsJustAstronomical 20 днів тому
The centrifugal force is a result of us using a rotating coordinate system here. The entire coordinate system is rotating along with the Earth's orbit so that in these coordinates the earth is stationary. This is basically saying that if you were orbital at one revolution per year that would not be fast enough to avoid falling towards the sun if you're close to the sun. If you're far away that would be too fast.

The Earth doesn't wobble on its axis. Go watch what happens to a spinning gyroscope in zero G. If the Earth were wobbling on its axis why is the entire solar system "wobbling" too? how is the Sirus star rising in the same spot? why is the rate *changing*? This explanation is just an old myth that we're taught because Copernicus said so. It doesn't fit the evidence. I don't understand how it really works (no one does) but I know this model is wrong.

It's not just astronomical! We have ice ages cycles since the start of the Pleistocene. However Milankovitch cycles have always been there and they did not create ice ages during the Pliocene and before. The important difference is the concentration of greenhouse gases in the atmosphere. Now, we will perhaps not have the next ice age because of man made warming of the climate. Check the NOAA pdf on glaciation cycles.
