Gravity holds almost everything together; the planets, our solar system, essentially everything 'big' in our universe.
For Earth, if gravity was suddenly 'switched off', the Earth would expand as everything that was densely held together by gravity suddenly separates. The atmosphere would dissipate, everything would turn into a giant chaotic cloud of matter.
On the atomic scale however not much would change. Atoms would still exist, as would molecules and probably some collections of them too. On such a small scale where everything is so close together and mass is so insignificant gravity is not as significant a force as it is in our day to day lives. At this scale we get what are called the 'strong' and 'weak' nuclear forces taking control along with electrostatic forces, holding the atomic nuclei together and keeping electrons orbiting, and other very important things.
So if we did not gravity, we would cease to exist. But on the atomic scale not much would change.
The same thing that happens every night when the sun disappears...nothing! Gravity on Earth is not dependent on the Sun. But life on Earth is, gravity would be the least of Earth's problems if the Sun dissapeared
Life on Earth is adapted to Earth's specific conditions such as gravity, atmosphere, and temperature, while life in space would face challenges like microgravity, radiation, and vacuum. Life on Earth has evolved over billions of years to thrive in its environment, whereas life in space would need to adapt through technology or genetic modifications to survive.
If the gravity of the Earth was 0, the law of uniformity would mean that gravity everywhere else in the universe would also be 0 and it therefore could not exist. If you somehow managed to make just the Earth's gravity 0 the planet would fly apart as a result of the centrifugal force of its spin and the Moon would fly off and orbit the Sun on its own.
You would weigh less on Mercury than on Earth due to its lower gravity. Mercury's gravity is about 38% of Earth's gravity.
If there was no gravity on Earth, everything would float freely in space. Objects would not be pulled towards the Earth's center, causing disruptions in our everyday activities, such as walking, driving, and even breathing. The absence of gravity would lead to a completely different and challenging environment for life on Earth.
gravity would be used in a sentence like this: The gravity of the Earth is a very important part of life.
Without gravity, everything on Earth would float off into space. There would be no atmosphere or oceans, and all living things would have a hard time surviving without the necessary conditions for life. The absence of gravity would also disrupt the orbits of celestial bodies, leading to chaos in the solar system.
Gravity is essential for life on Earth because it keeps our atmosphere in place, allows water to flow, and enables plants to grow towards the sun. Without gravity, our planet would not be able to support life as we know it.
Negligible gravity, no tides, no atmosphere, no life
Negligible gravity, no tides, no atmosphere, no life
First, keep in mind that this situation is utterly impossible, since gravity is a characteristic of mass, and the earth is massive. That said, without gravity life on earth as we know it would end. There would be no atmosphere, no water, no animals or vegetation of any kind.
Life on Earth has evolved to cope with the environment of earth. If the gravity were different it is very likely that life would look very different. It is likely that if the gravity differed by a large amount then life would not have evolved at all. Too heavy and Earth would have enormous amounts of hydrogen and would be a small gas giant. Too little and the earth could not keep hold of much of its atmosphere. As a result we would have far less CO2 and the surface would be much colder. Also we would loose our precious ozone layer and the surface would be bathed in solar radiation.
If Earth's gravity was a billion times stronger than a black hole's, everything on Earth would be crushed instantly under the immense gravitational force. The planet itself would collapse into a black hole due to the overwhelming gravity. Life as we know it would cease to exist.

No, Earth's gravity would not affect Pluto. However, the suns gravity does.
Everyone and everything would be everywhere. We would float around. In other words there wouldn't be no life.
Earth: Space: - is a planet - No gravity - supports life - Vaccum - gravity - No gravity or atmosphere - atmosphere
