The Earth rotates around the sun due to d curvature of spacetime. Why does not it fall into it(followig a spiral path?)
Most wud say, because of the tangential force that keeps the earth in its orbit... But how did this force originate when d spacetime was already curved because of the sun??
Also since 'spacetime' is curved, time chould also be curved around the sun...
How can this be explained???
Any reference to the Cassini Spacecraft slingshot???

SS u got 2 blev it cuz this theory has been proved...
During a solar eclipse( in einstein's lifetime) a star,s light was seen , which was obscured by d sun otherwise...
dis cud only happen if spacetime was curved...
Dude einstein was not a fool !!!

When our star was formed it would have ejected a lot of material, some of this material would have the correct momentum to follow on orbit in space.
You are rigth about time curvature, in fact gravity is so weak on the earth we really only notice the time curvature rather than the space as 1 second may seem quick for us but light can travel a long distance in this time.

Sir,
what is this space time, what is this space curve???
no body has proved these stuff, space curvature, space time etc. Those people who accept these therories they will enjoy these discussions, but those who are not convinced about such concepts it is really an irrelevant question.
Earth rotates around sun just because of gravity and some other forces which keep it revolving. Where did you get this idea that space curvature or curvature of space time is causing it????
And also if space curvature time is causing it why should it fall into it??
Could you please explain why somebody has to accept these theories??

The sun and planets formed from a rotating disc of gas and debris, when the sun formed space was curved because of it's gravity, the planets formed at different differences from the sun and their motions were maintained to equal the rotational speed of the parts of the discs they formed from, because the planets are in a friction free environment they are able to stay in stable orbits. Forget about time, it is not relevant.

The planets interior the photograph voltaic gadget (and, for the main area, their moons to boot) certainly are arranged in greater or much less a 2-dimensional airplane that way. that's no longer by way of fact of ways the solar distorts the spacetime around it, yet quite by way of way gas clouds tend to variety into action picture star structures. The gas clouds' very own gravity has a tendency to tug them from a around shape right into a disc shape earlier the planets variety, so while the planets do variety they finally end up close to a airplane. That mentioned, there are different smaller gadgets orbiting the solar, which contain comets and KBOs, that have orbits way outdoors that airplane, by way of fact they shaped in yet differently from the planets.

what force would cause the Earth to 'spiral in' towards the Sun?
