Gravity is a unique phenomenon which is certainly no stranger to human life, because it supports the existence of living things. The existence of gravity makes objects and living things float freely, making it difficult to carry out activities.
It’s no wonder that gravity is an interesting topic to discuss, because everything in the solar system seems to have its own gravitational force. You can listen to some interesting facts about gravity below.
1. History of the discovery of gravity

The existence of gravity was previously unnoticed by humans, before finally it was discovered by a scientist. This is what then makes the existence of gravity seem to continue to be studied for other scientific needs.
Reported National Geoographic, a scientist named Isaac Newton who discovered and formulated the existence of the theory of gravity around 1665 or 1666. The emergence of this gravitational force inspired these scientists to see apples falling straight down, not sideways or even up. This is what then gave rise to the theory of gravity.
2. The way gravity can occur

When you stand maybe you can maintain your body well, including when you walk and it seems you don’t have any difficulties. All movements of humans and living things on Earth are related to gravity, so everything can be done properly.
Reported NASA Space Place, Earth’s gravity stems from all of its mass, because it produces a combined gravitational pull on everything and living things that is on the Earth’s surface. Everything will seem to be pulled towards the Earth’s core which makes any object fall down easily.

If you look outside the solar system, there are actually lots of planets and stars that lie far away. It could be said that every celestial body has its own gravity, even living things would.
Reported AMNH, the level of gravity that exists in each solar system object can be different, for example the sun’s gravity is so strong that it can pull the surrounding planets including Earth to orbit. This is why gravity will feel different when astronauts are on Earth and when they are on the Moon.
4. Gravity can bend light

The force of gravity in the universe is no joke, even a small example can occur in the gravity that belongs to Earth. Gravity has its own power that allows it to move various objects.
Reported Science.org, gravity can even bend the presence of light, although that may not always be the case in some places. Light traveling through space-time can later be bent and warped, so that it appears to dive in the face of a massive object.
