¿Qué son los agujeros negros?

The video explores black holes, starting with Einstein's theory of relativity, which redefined gravity as the curvature of spacetime. It explains how black holes form from collapsing stars and discusses their properties, such as the event horizon and singularity. Detection methods include observing X-rays and gravitational waves. The video also touches on theoretical concepts like wormholes and speculates on the role of black holes in the universe's evolution.

What did Einstein's theory of relativity propose about gravity?

• Gravity is a force that pulls objects together.

• Gravity is the deformation of spacetime caused by mass.

• Gravity is a constant force throughout the universe.

• Gravity is unrelated to the mass of objects.

What happens to a star that is at least 25 times larger than the sun after it exhausts its atomic fuel?

• It expands into a red giant.

• It explodes as a supernova and then becomes a black hole.

• It turns into a neutron star.

• It becomes a white dwarf.

What is the event horizon of a black hole?

• The outer layer of a black hole that emits radiation.

• The center of the black hole where the singularity is located.

• The point where a black hole begins to form.

• The boundary beyond which nothing can escape the black hole.

What is a singularity in the context of black holes?

• A point where gravity is weakest.

• A place where light cannot enter.

• A region where time stops.

• A point of infinite density and zero volume.

What speculative idea about the Big Bang is mentioned in the video?

• The Big Bang was the result of a supernova explosion.

• The Big Bang was triggered by a massive asteroid impact.

• The Big Bang was caused by a collision of two galaxies.

• The Big Bang was the consequence of a black hole compressing all matter.
