Being just around 250 km away from Earth’s gravity the ISS (International Space Station) should experience at least 96% of Earth gravity. Still, astronauts abroad the station still float without the effect the gravity. Solve the conspiracy.
It is often said that ‘Jupiter protects the Earth’, what do you think about it? (Answer can be yes or no, and do support the answer with few statements)
The gravitational force of a black hole is so powerful that light cannot escape its gravitational pull. How do think the photon being massless is being influenced by the gravity of the Black hole.
