¿De qué está lleno el vacío?

The video explores the concept of change of state in physics, focusing on temperature changes and their effects on systems, such as water and magnets. It introduces the idea of spontaneous symmetry breaking, using magnets as an example, and extends this concept to the universe, discussing particle interactions and energy states. The video emphasizes the complexity and wonder of these phenomena.

What causes a change of state in a physical system?

• A change in mass

• A change in volume

• A change in pressure

• A change in temperature

What happens to a magnet when it is heated above its Curie temperature?

• It loses its magnetism

• It becomes stronger

• It changes color

• It becomes heavier

What is spontaneous symmetry breaking in the context of magnets?

• When a magnet becomes non-magnetic

• When a magnet loses its color

• When a magnet's atoms align in a specific direction

• When a magnet splits into two

What happens to the universe as it cools?

• It expands indefinitely

• It falls into a state of maximum energy

• It becomes completely empty

• It falls into a state of minimum energy

Why can't the universe be completely filled with quarks?

• Because quarks repel each other

• Because quarks are unstable

• Because quarks are too large

• Because of the Pauli exclusion principle
