Gravity

What in the hell is it?

What in the hell is it?

The distance from the tree limb you fell from to the ground.

What in the hell is it?

A harsh mistress

 

[DarkFury]

Something you use to your advantage not to pee on yourself.

 

[Arianrhod]

What in the hell is it?

That depends on whether you're pro- or anti-science.

 

[Votto]

Well according to science, gravity is the bending of "space-time".

Mkay, how do you bend empty space?

 

[hjmick]

A bitch.

Gravity is the force that attracts two bodies toward each other, the force that causes apples to fall toward the ground and the planets to orbit the sun. The more massive an object is, the stronger its gravitational pull.

Fundamental force
Gravity is one of the four fundamental forces, along with the electromagnetic, strong and weak forces.

It is what causes objects to have weight. When you weigh yourself, the scale tells you how much gravity is acting on your body. The formula for determining weight is: weight equals mass times gravity. On Earth, gravity is a constant 9.8 meters per second squared, or 9.8 m/s2.





Historically, philosophers such as Aristotle thought that heavier objects accelerate toward the ground faster. But later experiments showed that wasn't the case. The reason that a feather will fall more slowly than a bowling ball is because of the drag from air resistance, which acts in the opposite direction as the acceleration due to gravity.

Newton's Law of Universal Gravitation says that the force of gravity is directly proportional to the product of their masses and inversely proportional to the square of the distance between them

Sir Isaac Newton developed his Theory of Universal Gravitation in the 1680s. He found that gravity acts on all matter and is a function of both mass and distance. Every object attracts every other object with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. The equation is often expressed as:

Fg = G (m1 ∙ m2) / r2

• Fg is the gravitational force
• m1 and m2 are the masses of the two objects
• r is the distance between the two objects
• G is the universal gravitational constant

Newton's equations work extremely well to predict how objects such as planets in the solar system behave.

With that being said, when the busty waitress bends over you table and you get a boner, that is not gravity. That is you fixing be devoid of a BIG tip!

Gravity is something which we can describe the effects of, even quantify them mathematically, yet we do not understand the fundemental mechanisms of gravity at all.

What in the hell is it?

A theory believed only by cultists. We stay on the ground thanks only to God's benevolence.

The previous 2 posts are seriously misguided. If what you say were true, we would never have gone to the moon because we would not have been able to find it, nor would Sir Edmund Halley been able to predict the return of the comet named after him.

Now, I eagerly await the coming "moon landing was fake" assault, and Isaac Newton was a cultist who hated apples!

I missed the movie so I don't know what it is. I think it's a manifestation of another dimension and no space is empty.

That question suggests you havent dug too hard on the subject at all, Collectivist. Read up. Watch Through the Wormhole, all seasons if you dislike reading. Then, come back and funny your own question. We should all have a good sense of humor regarding what we're ignorant of.

... and a good helping of old timey math, not the uncommon core crap.

Gravity is a weak force, but it is the primary long-range force. Without it it could kill you as you'd float away into the atmosphere. It is a long-range force, so you can go quite a distance away from Earth and still feel the effects. It would be a very strong force if there is a mass large enough such as a black hole. Then it could pull planets, stars and everything else in.

Compare it to the two nuclear forces and the nuclear forces are stronger, but extremely short-range.

The electromagnetic force is stronger and also long-range, but it has opposite polarities and both attractive and repulsive forces. In large mass objects, it cancels each other out and its effect over long-ranges.

Gravity is pure attraction and long-range, so it is the most prevalent force and can form large objects in space such as a black hole which can continue to grow and attract more objects. Control gravity and you could be the universe master.

It's more about debris in space science (Kessler effect), but still an awesome film. Won 7 Academy Awards.

Personally, I thought the film was another lame hollywood space opera, predictable to the end. I did think the effects were well done.

I'm going to watch it again, I couldn't get interested in it the first time.
