What would happen if there was no Gravity?

How would it affect Animals and Plants?

How would it affect Chemistry?

Animals and plants - all would die instantly no gravity including atoms...

No electricity because basically assuming 0 gravity instantly

No planets because atoms have to have some gravity to stay together. It would be like the Universe froze. (assuming no kinetic energy is allowed.)

Chemistry absolutely no chemical bonding . No gravity no chemical bonding

Best analogy is the universe would freeze and all things with it. possibly literally as well no Gravity no energy no heat.

Gravity doesn't affect chemistry AT ALL.

Electricity is carried by charged particles, or electrons.

Interatomic bonds are 30 orders of
magnitude stronger than gravity, and not based on gravity
either. So basically all you said there is wrong

I get Interatomic bonds in that sense you are correct. Now I am not a physicist and I see you are an engineer so I will refer to you.

More of a learning point for me mostly subatomic question. Subatomic particles have mass and in order for a particle to have mass it must have some force of "gravity" I understand it would be a very small amount upon it?

Electricity , I understand electrons moving basically, but for something to move photons or electrons it must have some type of energy but also mass even though extremely small?

I guess that falls under the

Heisenberg Uncertainty Principle?

I'm thinking along the lines of Quantum Gravity and GUT and Planck scale

For the original question, I agree classical physics is likely the best way to answer it. :)

Thanks, but I'm only 14, so I do not understand what you were saying. I know that my question might sound scientific, but it is for my grade 9 assignment. Thanks anyway

It sounds like you've done a lot of reading of popular science articles or books, and have collected a lot of terminology, without having a context to understand how those terms relate to the underlying science. To get a start at really understanding the physics, without getting lost in a whole lot of magical words or "gee this is weird" authors, I would strongly recommend Richard Feynman's _QED: The Strange Theory of Light and Matter_. No jargon, no math, no "magical mysterious quantum" crap.

Atoms are held together by electric forces -- the nucleus is positively charged, the electrons are negatively charged, and they attract each other. This is equally true in quantum mechanics as it is classically. Molecules are also held together electrically, for the same reason. In the case of molecules, the electrons are "shared" among all the atoms, which contributes to the force holding them together as a group.

Gravity is completely irrelevant to subatomic physics. The forces between particles (for example, between the protons and neutrons in a nucleus, or the forces holding the quarks together inside a proton) are unrelated to the masses of those particles.

Words like "quantum gravity", "GUT", and "Planck scale" have nothing whatsoever to do with chemistry, or geology, or in fact anything at all on the scales of physical objects you see around you.

No, even in the absence of gravity things still posess INERTIA, which is a property of the Higgs boson. Mass does not come from gravity.

Good point on Higgs particle, didn't know they discovered it 2012 until now. :)

the universe will no longer exist as we know it. there would be no stars and nothing.

The answer to a question needs to keep in mind the ability (based mostly on age and education) of the person asking to understand the answer. People who have or have had children come to understand this very quickly. The same question asked by different children will produce different answers depending on comprehensive ability. "Where do babies come from?" is a classic example. Always check the profile.

I came from a place called Scunthorpe - So my mummy said!

That's a good point. :) I saw the profile , but I don't have children so I probably should have kept that more in mind in my first answer, communication is the key. :)

There would be nothinig but the atomic strong forces to hold things together. Therefore, all of existence would be nothing but a cosmic sort of "dust," but on a very small atomic/subatomic scale. Bonded ions and quarks would be the only things to stick together.

Not quite. Without gravity, you would still have neutral atoms, and even small molecules (which form electrostatically, not gravitationally). What you _won't_ have is *dust*, which consists of macroscopic grains which have agglomerated due to gas clouds condensing to higher than ambient pressure through gravity.

Your meat would be very dry - sorry misread the question, thought it said Gravy.

Assuming you were safely sequestered within a ship enveloped in a protective gravity field a few light years away from any sun, planetary body or black hole and further assuming the speed of light barrier is independent of gravity.

You would not notice any changes even as it would be race, as nuclear particles pushed from star cores began to expand radially ( some in your direction ) while the sub atomic matter released by black holes speed across space to impact your miniature habitat and terminate your brief theoretical existence by ripping you asunder.

How would it affect Animals and Plants?

Dead as we would have no atmosphere - in fact there would be no earth, No sun or any other planets.


How would it affect Electricity?

Not at all


How would it affect Space and Universe?

Depends if gravity as a universal vanishes or if this just happens locally. If universal - the the universe as we know it will cease to exist.


How would it affect Chemistry?

Not at all.

If there was no gravity everything would be dispersed such that you wouldn't have anything visible in the universe. It would just be a bunch of hydrogen molecules drifting through the infinite universe. So dispersed you couldn't even call it a gas. Without gravity none of the other elements would exist.

Nothing would happen without gravity all that exists the sun the planets the universe run on gravity.
