Is the theory of Gravity that are widely considered reasonable?

Question

If every matter that has mass is considered to have a Gravity in them, it would make WD5 gravitationally attracted Earth and Mars. If Gravity is the reason that held the position of every planet around the Sun, and the planets orbit in a form of centrifugal force, any planet that are hit by WD5 would send it out of it's original orbit. Not only that, every big object that travel across the solar system will hit a planet and not avoid it like the one that almost hit Earth on 2004 (1994).

The theory of Gravity that are widely considered is calculated base on low technology or very little technology. Those people made their calculation without even kwowing what really is space environment. You don't have to agree with me, but in my calculation the theory of Gravity that are widely considered has no safety in mind.
What is your opinion ?

Calculation in 4D, forth dimention (Quadrant Pythagorean)
The Gravity of the Moon is 1/6 of the (Moon Gravity) =1.66%. If you would drop a tenis ball from 5 feet towards the ground on Earth surface, let's just say the ball touch the ground (Earth Gravity time1 sec.) =100% and equal to 30 frames per second. Now we do the same thing on the Moon surface, drop a tenis ball 5 feet towards the ground (Moon Gravity Time) =? The frame per second on the Moon is 1/6 of 30 frames per second, so here on Earth the frame per second of the Moon =? I,m sure you can do the rest of the calculation cbirch92. You can arrange it in more formal way, and if you find some of my math incorrect pls. make the necsesary adjustment. This is what you requested and this is how I can possibly write it down tnx

PLS. use 2nd equation tnx.

Answer 1

Are you questioning gravity?

No, things like asteroids hitting the Earth are too insignificant to send it out of orbit (or, more so into orbit). Probably millions of asteroids and comets and meteros have come into a collision course with the planets over the years, but there is no significant fluctuation. Also, the gravity that attracts the planets to the sun is relatively insignificant at Earth's distance, other than it making us spin =) ; cyntrifical force does the opposite effect, keeping us in balance.
There is actually great evidence of gravity, look at black holes, stars, planets and you. If you are floating right now, let me know, but i doubt it....

Answer 2

Gravity is only a significant force when objects are relatively close. It decreases with the square of the distance. An object 100,000 miles away is attracted only 1/4 as much as one only 510,000 miles away.

Asteroids don't approach a planet (like Earth) dead on, they are usually moving in a line that may be close to Earth at one point. At that one point the Earth's gravity may affect the asteroid but it won't make it turn 90 degrees and suddenly come at the Earth - all it can do is bend the orbit a bit. An object the mass of WD5 has a lot of momentum, and Earth's gravity isn't enough to completely change an asteroid's orbit.

Answer 3

dude...

mars is roughly the size of earth. WD5 is about 150 ft wide. its like an atom hitting a basketball.

the largest asteroids are at most a few km in diameter. the earths has a 12,000 km diameter and has a mass of 5.9736×1024 kg. it can hold the moon is position with its massive gravity. its huge.

the only way anything could ever make earth change its orbit is if another planet comes along and hits head on with earth.

no offense, but if i have to choose between proven calculations that have been verified by literally thousands of scientists and what you have "calculated" in your basement with the help of wikipedia and a calculator im gonna go with the first one every time.

and just so u know. gravity is very weak and its influence drops off extremely fast with distance. for something to orbit earth it would have to be very small, going at a slow speed, and come very close (the moon doesnt count, it originated in the orbit of earth).

all comets, asteroids, meteors, they are attracted to everything. mostly the sun, thats why all of them orbit the sun.

so in short, your wrong. what youve "calculated" doesnt mean **** considering you didnt calculate anything. you massively over estimated the power of a planets gravity over long distances and didnt even really do any calculations at all.

show me some math and then ill believe u. otherwise, your wrong.

Answer 4

The calculation of the gravitational force is extremely precise. You are correct that when Newton developed the universal law of gravitation he didn't have much technology at his disposal but we do... and the equations still hold. We understand the way gravity acts on ordinary matter to an astounding precision. Gravity is a fact. The question that remains to be answered is "What is gravity?" Einstein seems to have partially answered that question but we still have more to learn.

By your viewpoint we can't be sure that the earth is really round because that was discovered by Eratosthenes over 2000 years ago when they were even more low tech. The fact that they were so low tech, yet correct, is what makes them geniuses.

Answer 5

I am very happy that I don't have to agree with you.

Everything is attracted by everything else. It does not mean that everything will hit everything else.

The Moon is attracted by Earth. That is why it stays in orbit. However, the Moon will not hit Earth. In fact, the Moon is moving away (about one inch per year).

The theory of gravity was not "built" to provide safety, but simply to explain how things are attracted by other things.

By the way, WD5 will not hit Mars because of the attraction. It will hit Mars because Mars is in its way.

Answer 6

i cant really agree or disagree--but when someone gets a space vehicle to Saturn and Jupiter and gets the vehicle purity close to where they want them to be--i would say at the study of Gravity has come a long way- Sorry im not sure what your Q is--

Answer 7

You forget about Inertia, and the fact that as you go further from an object the pull it has on you becomes weaker.

Answer 8

Gravity isn't a theory. It's a law. And you must obey it.
