Physicist I am a physicist and it comes naturally to me that all planets are spheres mainly because of gravity. The gravity of a planet is directly proportional to the planet’s mass and inversely proportional to the planet’s radius. Gravity can be calculated 6.67*10^-11(planet mass/planet radius^2). This also means that, according to Newton, the earth’s rotation does not have a particularly large effect on gravity. The sun has the greatest gravitational force in our solar system, approx. 247N/kg or 247 m/s^2, which means that if you fall one meter on the sun, you will hit the “ground” with a speed of 247 m/s. Similarly, 1 kg on the Sun will be 247N, while on Earth 1 kg will only be 9.81N. We have formulas to calculate the curvature of the earth, and these are very accurate. Why do some people think the earth is flat? When all scientific findings indicate that all planets are spheres?All scientific sources on the shape of the plates are available to anyone. Flat earth documentation is not available, logically enough because it doesn’t exist. As a physicist, I must be able to explain observations and natural phenomena through mathematics and scientific models. This is exactly what makes physics so exciting! A model must be able to explain all phenomena and observations, you can do that on a sphere. On a flat earth it is not possible, so above all one does not use false values. The globe rotates 360 degrees/24 hours. Our solar system is moving at 600,000m/s towards the center of the Milky Way where there is a gigantic hole with an enormous gravitational force. Since the acceleration is constant, we do not  notice any of this, so Newton’s second law is fulfilled. If, on the other hand, the earth’s rotation increased or decreased, we would notice it because Newton’s second law will no longer be fulfilled. I love my subject and am happy to answer questions, but do not respond to sarcasm. – Physicist Flat Earther The earth is flat because I rolled a marble on a table and it disappeared bottom up. Although when I moved my head up a little to be level with the table, it didn’t do that for some reason. I brought a small boat back into view that was too small to see, although I can’t bring the sun back for some reason. The bible teaches the world is flat, although I cannot find one verse that teaches this. The flat earth map is accurate and explains observation, although it doubles and triples distances in the southern hemisphere for some reason. But the southern hemisphere kind of doesn’t matter. The globe earth conspiracy means millions are in on the secret, yet not one person has leaked the truth despite the anonymity of Wikileaks etc for some strange reason, The flat earth is hidden from the populace because it proves that God exists. Although the scientific view proves an eternal God because the cosmos is so finely tuned … Continue reading A message from a physicist and a message from a flat earther
