Aside from the bending of space already having been proven, think of this video and see how the earth is falling in a circle once a year. Space is certainly being bent. Gravity is what causes the bending of space(time). On a separate note, Einstein will for sure be proven wrong one day, since his theory of relativity does not hold up with Quantum Mechanics, at the microscopic level, so somewhere there is a gap that needs filling/adjusting.

Does gravity itself not slow things down? Like is the earths orbit getting ever so slightly closer to the sun, or is it at a set distance always (at a given point in orbit)?

Sir, as there is nothing to slows down the moon... Do you think we can also say symmetrically the net forces will be cancel out as moon is following a sort of circular path.

Thank you sir for clear it to me

I recently had the thought "why doesn't everything fall into a black hole? Then I thought - if you replaced the sun with a black hole that had an equal mass - then all the planets must then stay in orbit rather than be eaten by the black hole for the same reason we dont fall into the sun. While I understood that, I didn't necessarily know WHY. I figured it had to do with being trapped at a particular place as it falls towards the sun.

thanks for this! i now know!

I was wondering than i said let me ask yt than i found this guy now i can go sleep

The energy which caused the Earth to move is,as I said in my previous reply, from the Big Bang explosion. When it orbits, Sun's gravity is "consumed" by keeping the planet from "getting away" ,rather than by attracting it. In the Universe there is no atmosphere which causes things to slow down like here on Earth. If you were in Space and threw a ball, it will not stop (unless it gets close to a massive object like a planet,star etc.).Likewise,if you were the Big Bang and threw Earth, it will not stop, it will eventually get into the orbit of Sun. Sun's gravity is used so Earth stays on its orbit and not travel further and is "consumed" that way.The Sun cannot therefore bring the Earth closer to itself unless its gravity force increses.

Could the Earth body's trajectory shift to a dangerous degree so that eventually it would go too far or too close to the Sun and thus, be either engulfed by the Star or our life exterminated (too cold or hot)? I have in mind an event of a magnitude capable of moving the Planet.

What I'd like to have explained is how the Earth and the other planets just happen to be going exactly the right speed to neither fall into the sun, nor fly away from it.

So it the mmon always falling toward Earth?

Im curious to know if this is the case then why satellite uses thrusters to maintain its orbit and prevent to fall on the earth?

@JonBergmann1

Why earth or other planets do not stop orbiting? When we make a model of space time curve, the objects orbit around the heavier objects which is sun, so why they don’t stop orbiting at the end of finishing their orbit, I have heard that of everything starts, so they have to stop sometime in their way. But planets don’t stop orbiting forever.

Coincidence *I think not*

Isn’t it that the planets are formed at the equilibrium point such that the centrifugal forces matches the gravitational force? Of either one were out of whack, say the gravitational force weaker, planets would indeed flying away. No?

So out there in space since we don't have any air but each of planets have their own gravitation force like Jupiter which stops most of the asteroid to hit the eart because of its gravitation pull....so my question still the same sun has a larger mass so has larger gravitation pull so why isn't it pulling any other planets. Just like Jupiter binding the asteroid to move around its belt

Could it be that the planets magnetic fields keeping the planets in their orbit. So the mass of the sun or planets pulls in moons and planets to them but the sun's and planets magnetic fields radiating out keep them in their orbit. Is it not odd that Venus and Mars with no magnetic fields have no moons orbiting them. Just my amateur theory. Would love to see proper mathematical model to see if true.

Sir, I have a question. Why doesn't the velocity (speed) of a satellite changes when it's falling into the earth's centre.....umm I mean yeah it's orbiting the sun but why it's constant speed? Why the gravity isn't effecting it's speed?

This graphic explanation is believed to enlighten many learners in understanding the basics of gravitational orbit.

The satelites have engines that turn on in order to adjust the velocity to keep in orbit. how does the earth "correct" its speed in order to keep around the sun? if the explanation that there is no atmosphere to make it slow down, then the satelites wouldnt need to corret their speed too...what im missing?

@JonBergmann1

Жыл бұрын

That is a really great question. Though I am not 100% certain - I would say that the satellites are facing at least some atmosphere - so over time they slow down - thus the need for the engines. In the case of the earth, it doesn't have to fight a solar atmosphere so it keeps on orbiting.

If the gravitational pull of the sun is just strong enough to hold the earth in its orbit, never letting it drift away and never pulling it closer and eventually crashes into it. Then what about the other planets that are closer and farther away from it. How does gravity work for them. Basically the same way I'm guessing but shouldn't the gravity be stronger for nearer planets and weaker for farther planets.

Planets that are closer have more velocity, so they orbit the Sun faster, while planets that are farther orbit the Sun slower.

They are captured in the gravitational pull of the earth. They don't orbit because they make a more direct hit in their trajectory. Note that many do orbit and never reach the earth. It is all about the direction when they encounter the gravitational pull of the earth.

Earth's speed V is just a fixed speed, not an acceleration, while the Sun's gravity is an acceleration (G). I thought that the Earth is falling into the Sun, but it's taking billion years to do so (or the opposite) because of the almost perfect balance between V and G.
