Best answer: Totally wrong, because this doesn't cause the seasons. There are seasons because the Earth's spin axis is not at exactly 90 degrees to the plane of its orbit.

Best answer: Besides low gravity, there is the solar wind of particles. These erode the atmospheric molecules. Does not happen to Earth very quickly, since a strong magnetic field is a shield. Moon and Mars have none, and it is not within most reasonable technology to create such a shield (of course, N. Tesla knew how!). So... show more

Best answer: x = sqrt(2) + sqrt(17) x^2 = 2 + 2 * sqrt(2) * sqrt(17) + 17 x^2 = 19 + 2 * sqrt(34) x^2 - 19 = 2 * sqrt(34) x^4 - 38x^2 + 361 = 4 * 34 x^4 - 38x^2 + 361 = 136 x^4 - 38 * x^2 + 225 = 0 Now, if divisors of 225 can provide a solution for this polynomial, then sqrt(2) + sqrt(17) is rational. If not, then it... show more
