Does Newton's Law of Gravity still Stands?

Newton' Law of Gravity VS Einstein's Law of Relativity

Answer 1

Thank you very much. This whole series is very interesting to watch.

Answer 2

I once heard a scientist at the Jet Propulsion Laboratory claim that Newton's equations worked perfectly well for planning interplanetary trajectories.

If that's true, that's not trivial; that's a bit like thowing a marble from New York to Los Angeles so accurately that it hits the dime you were aiming for.

I'd answer that Newton's observations concerning gravity are "roughly" correct: they have tremendous predictive value concerning the behavior of objects in a gravity field, but the equations are not based on a theory of space as adequate as what Einstein articulated.

In some situations, then, Newton's equations will fail to give correct answers, I figure. But I don't have an example in mind; I'll leave that to any physicists out there.

Answer 3

Yes, but according to Einstein´s theory, gravity isnt absolute but relative. To make it simple, i´ll say gravity depends of the mass of each other object in the universe, its position and its distance.

Answer 4

Yes and no. In limited situations, like dropping an apple, it works fine. But Einstein's theory of relativity proved that large masses like planets and suns actually bend space and time, causing other masses to "fall" towards them because of the curvature.

Answer 5

Pretty much. As far as our general needs, it works fine. Relativity is just a more comple explanation.

Answer 6

"Stands"? Not sure what you mean.

Have you considered anti gravity through mind over matter?

Answer 7

Yes. Are you floating in mid-air now?

Answer 8

Why dont you jump off the building and see for yourself?

Answer 9

yes,what goes up must fall down.

Answer 10

yes it does stands.
jump in the air and if u come down means it stands
and if u dont......................
means we all are living the air ;)
