Gravity is a force that to hold the universe together.

Mhm, it keeps the planets in place and circle around the Sun's gravitational pull, like how the Earth's small-like gravitational pull keeps the moon to circle around our planet,  and as a perk it makes the 80% water that around this whole place to have high and low tides.
