Gravity is not an invention but rather a fundamental force of nature that exists in the universe. However, if we imagine a hypothetical scenario in which gravity did not exist from the beginning of time, the consequences would be significant and would likely prevent the formation of the universe and life as we know it.
Here are some potential consequences of a universe without gravity:
No formation of stars and planets: Gravity is responsible for the formation of stars and planets. Without gravity, the clouds of gas and dust that form stars would not be able to collapse and coalesce, preventing the formation of stars and planets.
No galaxies: The force of gravity is also responsible for the formation of galaxies. Without gravity, there would be no gravitational attraction between galaxies, and the universe would consist of isolated pockets of matter.
No structure: Gravity holds all objects together, from the smallest particles to the largest structures in the universe. Without gravity, structures like buildings and bridges would not be able to maintain their shape or hold together.
No tides: The gravitational pull of the moon and the sun on the Earth's oceans creates the tides. Without gravity, there would be no tides, which would have significant ecological consequences for marine life.
No life: Without the formation of stars and planets, life as we know it would not be possible. Life on Earth relies on a complex interplay of physical laws, including gravity, that allow for the formation of stable environments in which life can thrive.
Overall, if gravity did not exist, the universe and life as we know it would not be able to exist. The existence of gravity is fundamental to the structure and function of the universe.
