    That's pretty bad. It completely misinterprets certain concepts like orbital mechanics (why would an object spiral into the parent body? That violates energy conversion) Meanwhile the L4 and L5 points are not necessarily stable. This is a major mistake that was made here. L4 and L5 are only stable for the case where one of the bodies is far more massive than the other body, which in the case of the system Earth-Sun is true. This video introduces a lot of misunderstanding.

    Click bait using milankovich cycles. Anyone here that understands milankovich precession could help me out with a dilemma regarding moments of the seasons and the cycle of milankovich assumptions. If you divide the precession into 360 degrees at 180 degrees (around 12900 years ) the earth's inclination axle wobbling will change in opposite direction, the hemisphere that used to near of the sun on summer seasons now is far from and is in winter seasons, and vice versa for the other hemisphere. (Solstice june/December). But where would be at 90 degrees/270 degrees, (6400 years ) should the summer/winter seasons be happening at the equinox months and springs/autumn on Solstice months? If earth wobbling on milankovich precession at quarter of the turn 90 degrees at Solstice positions the inclination 23.5 will be in the same position as actual position now on the equinox. So every 6400 years summer/winter months would change for spring/autumn months and vice versa. Anyone could help me out here and tell me what I am doing wrong. Thank you

    My video about precession gets into this: kzread.info/dash/bejne/k5iu2pdtZ9Pak84.htmlsi=jFbUGuD1kQDE0I8g. The issue is whether or not you're calculating the year based on the position of the earth (a sidereal year) or based on the seasons (a tropical year). Since our calendar is based on the tropical year, the timing of the seasons won't change, but the constellations in the sky in a given month will change.

    There's a bulge around the equator from the rotation of the earth. Since the earth is not a perfect sphere the sun and moon's gravity pulls on one side of the earth more causing the precession.

    The thing is we need farming. We need industry. These aren't negotiable. Otherwise, we'd still be in the stone age. The mistakes made by the industrialists of the world have benefitted mankind greatly. Yes, there is a cost. Every action has effect. If we start carbon footprint madness then we will sink back into a stone age. Man is adaptable. The planet will not die, and it bounces back from whatever insults its taken over the last several million years. Volcanic activity and meteor hits have had deadly impacts on the planet. The planet survives. Short of a nova of our sun, this planet will endure. What bothers me more is environmental pollution and that includes garbage. Spilling poisons into water ways and burying it into the ground will kill eco-systems and people, alike. To me, that is much more important. Without ground water and healthy soil there is no cattle or chickens, or vegetables. We starve.

    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?
