If we can’t get exact solutions, then how do we know when our approximate solutions are any good? A gravitational wave is an invisible (yet incredibly fast) ripple in space.. We’ve known about gravitational waves for a long time. Q: What exactly is the vacuum catastrophe and what effects does this have upon our understanding of the universe? The escape velocity from the surface is about 20cm/s (less than half a mile per hour), which means that if you were walking around on it you’d have to be very careful to not accidentally push off into space. Then, what does 9.81 tell us? and why every thing which has mass has gravity what is the reason behind this force of attraction? 2 Magnetic and electric forces are also long-range, but gravity is unique in being both long-range, and always attractive, thus never cancelling out (unlike electromagnetism, where the forces may either attract or … Thank you for answering this, but I was wondering how big something would need to be to actually move a person towards it. Found inside – Page 428This discrepancy is noticeable only near light speeds . ... It suggests that the gravitational pull the Sun exerts on the planets of the Solar System , for example , takes place instantaneously over millions of kilometers . If so, where? If there was a space vehicle this large (somehow this vehicle is a sphere), would it be able to pull people into space simply by coming near the earth? Clearly, the earth does not have enough mass to power a nuclear fusion reaction due to the force of gravity. Couldn’t they “prove” anything they want? The reason I bring this up is this… If I filled a glass with water and spun it on its center point, the water wouldn’t spin with the solid container, rather stay stagnant or slightly effected. The force of Earth’s gravity is the result of the planets mass and density – 5.97237 × 1024 kg (1.31668×1025 lbs) and 5.514 g/cm3, respectively. But don’t get too concerned, the Sun should swell up and swallow us long before then. Although the other forces act over different ranges, and between very different kinds of particles, they seem to have strengths that are roughly comparable with each other.
