¿De Dónde Vienen Las Galaxias?

The video explains the formation and evolution of stars and galaxies, highlighting the role of dark matter and the observable universe. It discusses the early universe, the formation of star clusters, and the challenges in defining galaxies. The James Webb Space Telescope's mission to study the first stars and galaxies is also introduced.

What allows us to understand the lifecycle of stars and galaxies despite their long formation times?

• Direct observation of a single star's lifecycle

• Using time-lapse photography of stars

• Observing different stages of similar events across the universe

• Simulating the entire lifecycle in a laboratory

What is the primary interaction through which dark matter influences the universe?

• Weak force

• Electromagnetic force

• Gravitational force

• Nuclear force

What is one of the main challenges in understanding the formation of the first galaxies?

• The rapid evolution of galaxies

• Inability to detect dark matter

• Lack of technology to observe distant galaxies

• Uncertainty about the minimum size of dark matter clumps needed to form stars

Why is it difficult to define when a star cluster becomes a galaxy?

• Due to the lack of a clear definition of a galaxy

• Because galaxies are constantly changing

• Because star clusters and galaxies are the same

• Due to the presence of dark matter

What makes the James Webb Space Telescope particularly useful for studying early galaxies?

• Its ability to travel to distant galaxies

• Its capability to capture visible light

• Its large size compared to other telescopes

• Its sensitivity to infrared wavelengths
