Premio Nobel 2011: La Energía Oscura feat. QuantumFracture

The video discusses the movement of galaxies and the expansion of the universe. Initially, it was expected that the universe's expansion would slow down due to gravitational forces. However, in 1998, it was discovered that the universe is actually accelerating. This acceleration is explained by Einstein's theoretical model, which introduces the concept of vacuum energy or dark energy. This energy causes space to expand, pushing galaxies further apart. The video explores the implications of this discovery, suggesting that if vacuum energy is the correct explanation, the universe will continue to expand, becoming increasingly isolated and empty.

What is the observed relationship between the distance of galaxies and their speed of moving away?

• Distant galaxies move away faster.

• Closer galaxies move away faster.

• Distant galaxies move away slower.

• All galaxies move at the same speed.

What was the unexpected discovery about galaxies made in 1998?

• Galaxies have stopped moving.

• Galaxies are accelerating in their movement away.

• Galaxies are moving away at a constant speed.

• Galaxies are moving towards us.

What concept did Einstein propose that helps explain the acceleration of galaxies?

• String theory

• Vacuum energy or dark energy

• Black holes

• Quantum mechanics

What is the potential future of the universe if vacuum energy is the correct explanation?

• The universe will collapse.

• The universe will become more crowded.

• The universe will remain static.

• The universe will continue to expand and become lonelier.

What is one possible modification to our understanding of gravity that could explain the universe's expansion?

• Galileo's theory of inertia

• Kepler's laws of planetary motion

• Einstein's general relativity

• Newton's laws of motion
