Gravity is one of those things we take completely for granted. And there are two things about it that we take for granted: the fact that it is always there, and the fact that it never changes.

If the Earth's gravity were ever to change significantly, it would have a huge effect on nearly everything because so many things are designed around the current state of gravity.


Before looking at changes in gravity however, it is helpful to first understand what gravity is.

Gravity is an attractive force between any two atoms. Let's say you take two golf balls and place them on a table. There will be an incredibly slight gravitational attraction between the atoms in those two golf balls. If you use two massive pieces of lead and some amazingly precise instruments, you can actually measure an infinitesimal attraction between them.

It is only when you get an gigantic number of atoms together, as in the case of the planet Earth, that the force of gravitational attraction is significant.

The reason why gravity on Earth never changes is because the mass of the Earth never changes. The only way to suddenly change the gravity on Earth would be to change the mass of the planet. A change in mass great enough to result in a change in gravity isn't going to happen anytime soon.


Could we survive without gravity?
Without gravity, the water in oceans, rivers and lakes would disappear, leaving Earth with no water supply.

But let's ignore the physics and imagine that, one day, the planet's gravity turned off, and suddenly there was no force of gravity on planet Earth.

This would turn out to be a pretty bad day. We depend on gravity to hold so many things down -- cars, people, furniture, pencils and papers on your desk, and so on. Everything not stuck in place would suddenly have no reason to stay down, it would start floating. But it's not just furniture and the like that would start to float.

Two of the more important things held on the ground by gravity are the atmosphere and the water in the oceans, lakes and rivers. Without gravity, the air in the atmosphere has no reason to hang around, and it would immediately leap into space.

This is the problem the moon has -- the moon doesn't have enough gravity to keep an atmosphere around it, so it's in a near vacuum. Without an atmosphere, any living thing would die immediately and anything liquid would boil away into space.

In other words, no one would last long if the planet didn't have gravity.

If gravity were to suddenly double, It would be almost as bad, because everything would be twice as heavy. There would be big problems with anything structural. Houses, bridges, skyscrapers, table legs, support columns and so on are all sized for normal gravity.

Most structures would collapse fairly quickly if you doubled the load on them. Trees and plants would have problems. Power lines would have problems. The air pressure would double and that would have a big effect on the weather.

What this answer shows you is just how integral gravity is to our world. We can’t live without it, and we can't afford to have it change. It is one of the true constants in our lives!



What is zero gravity?
Zero gravity is the condition or state when your body becomes weightless. For example, on Earth, we have a gravitational field of 32 feet (9.8 meters) per second squared. At the state of zero gravity, the apparent or net gravitational force on your body shrinks to zero. At that point, your body becomes weightless.


What if Earth’s gravity becomes zero?
Just like objects and people, Earth is also attracted by the sun’s gravity. If Earth’s gravity became zero, nothing would hold it and chances are that its inner core would eventually burst in a lethal titanic explosion due to intense pressure. Earth would break into pieces that would float around space, wreaking havoc.


What does zero gravity feel like?
Zero gravity or weightlessness lets you float effortlessly due to the absence of acceleration forces on the body. This condition is similar to that of being in water where you are able to float with just the slightest effort.


Can humans live in zero gravity?
It might seem like a fantasy to float weightlessly through the air but practically, the human body would go through negative change, such as muscle and bone atrophy while living in zero gravity. Even the rivers, lakes and oceans on Earth wouldn’t stand in zero gravity, without which humans cannot survive.

Seeing all these makes me fear and respect God the perfect creator.

Without gravity, Earth wouldn’t orbit the sun!
This time it’s the Sun’s gravity that keeps us orbiting it.
We’re very lucky as it keeps Earth at the perfect temperature so it’s not too hot or cold

Nice educative post to start the day..

But I think we need to experience this gravitational pull problem (or even an earthquake) specifically in Aso rock and its axis (The senate, CBN and house of representatives, etc). Because, those guys are really doing a lot of damage to the image and masses of the country...

Social media has done more harm to us than good. Social media should be regulated for a society like ours. I mean this thread is super educative but our youths won't see it because of pennis and vaagina claiming influencers.

Insightful....this is the reason I fear God ..without God whose power is constant and who never get tired or know what it feels to be a failure is not in charge of his creation...we would have been in trouble...God gave us beautiful world and knowledge of thier names..our body and it different parts..freedom of choice with conscience to help us live right and in peace with other humans...but we say no..and live in selfishness and wickedness...if not how can Whiteman have constant access to basic good life like constant water,electricity, good road , hospital etc but here in Africa opposite is what we get ..because we have a mindset of self and self..money for public good is been looted by official entrusted to manage it... if the gravitational force can double on wicked people Africa streets will be deserted
