How far from earth do you have to be to experience weightlessness?

You have to be outside of the gravitational pull in the atmoshpere. Answer: Weightlessness can be achieved:* in Earth's atmosphere in an aeroplane doing a dive or on carnival rides (Drop of Death)* when in orbit around the Earth or other body.* there are several points (Lagrange points)in the Earth/moon system where the gravitational attraction of the two bodies cancels out producing weightlessness.


What does the pull of the moon have to do with ocean tides?

The gravity of the Moon. The gravitation of the Earth and the Moon work on each other. The side of the Earth nearest the Moon receives the greatest effect of the Moon's gravitational pull, creating the bulge in the ocean and high tide beneath the Moon. The bulge on the far side of the Earth is being spun away centrifugally from the center of the combined Earth-Moon mass.


Why would gravitational lensing create multiple images instead of just a distorted one?

Gravitational lensing can create multiple images due to the bending of light rays around a massive object, like a galaxy or galaxy cluster. The light from the source gets bent at different angles, leading to multiple paths the light can take towards the observer. This results in multiple images of the same object being seen from different angles.


Will the Moon ever disappear?

the moon is slowly going away but it'll take millions of years before it does. the moon isn't really doing a perfect circle around the earth, it is slowly spiraling away. Don't worry thought you'll never get to see that day


Which planet would you double your weight on?

You would double your weight on Jupiter due to its strong gravitational pull. The gravity on Jupiter is about 2.5 times stronger than on Earth, so a person weighing 150 pounds on Earth would weigh 375 pounds on Jupiter.
