Why Galaxies are Fidget Spinners #shorts #science

The video explores why galaxies are often disc-shaped, primarily due to gravity and rotation. It explains how these forces interact to form the disc shape, similar to a fidget spinner. Additionally, it introduces alternative theories suggesting that galaxy mergers or gas filaments could also lead to disc formation.

What is the primary force responsible for the flattened shape of galaxies?

• Electromagnetic force

• Gravity

• Magnetism

• Nuclear force

How does centripetal force affect the shape of a galaxy?

• It pulls the galaxy apart

• It pushes everything towards the center

• It causes the galaxy to expand

• It has no effect on the galaxy

What role does swirling motion play in galaxy formation?

• It accelerates the collapse of the galaxy

• It prevents the collapse by maintaining rotation

• It causes the galaxy to lose mass

• It has no significant role

Which of the following is a proposed alternative method for disc formation in galaxies?

• Galaxies shrinking

• Galaxies merging

• Galaxies evaporating

• Galaxies splitting apart

What is another way galaxies can grow into disc shapes besides merging?

• By splitting into smaller galaxies

• By shrinking in size

• By adding filaments of gas

• By losing gas
