Why is gravity the weakest force?
According to string theorists’ best ideas, gravity is so weak because, unlike the other forces, it leaks in and out of these extra dimensions. The proof of this might come through experiments that probe the gravitational attraction between objects that are very small distances apart.
What force holds planets and galaxies together?
gravity
First, gravity is the force that pulls us to the surface of the Earth, keeps the planets in orbit around the Sun and causes the formation of planets, stars and galaxies.
How does gravity hold the universe together?
Gravity is the powerful force that glues our universe together. The gravitational pull of the Sun and Moon creates the tides on Earth. Far beyond our solar system, the irresistible force of gravity is collapsing stellar cores into amazing – and bizarre – objects in our universe–neutron stars and black holes.
Is gravity stronger than the weak force?
The “weak” nuclear force is 10 to the 25th power stronger than Gravity. That’s 100,000,000,000,000,000,000,000,000 times stronger! Electromagnetism – the force we know best – is 10 to the 36th power stronger than Gravity.
Are galaxies held together by gravity?
A galaxy is a giant, spinning object made of gas, dust, and stars held together by gravity. Galaxies come in different shapes and sizes and can contain billions of stars. Most occur in groups that are also held together by gravity.
How does gravity affect galaxies?
Every object in space exerts a gravitational pull on every other, and so gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit. It can also cause life-destroying asteroids to crash into planets.
Does gravity hold our galaxy together?
Most galaxies are not alone in the vast expanse of space, but are connected to one or more other galaxies by gravity. The same force that holds you onto the Earth can keep many individual galaxies bound together. This makes them a good probe of the history of structure and galaxy formation.
Do gravitational force is the weakest force in nature yet it is responsible for holding our solar system Why?
Answer: look ,,, gravitational force is weekest from the force of strong and weak nucleus, and electromagnetic force.
