Los LÍMITES del UNIVERSO en una fotografía

The video explains how observing distant stars and galaxies allows us to see the past due to the finite speed of light. It uses analogies of historical information transmission to illustrate this concept. The Hubble Deep Field image is highlighted for its role in understanding galactic evolution and supporting the cosmological principle, which states the universe is homogeneous and isotropic. The video also compares the advantages of space telescopes over Earth-based ones, emphasizing the potential of the James Webb Telescope.

Why do we see distant stars and galaxies as they were in the past?

• Because light travels instantaneously.

• Because telescopes distort the images.

• Because stars and galaxies are moving away from us.

• Because the speed of light is very small compared to cosmic distances.

What is the significance of observing the Andromeda galaxy?

• It provides a view of the galaxy as it is today.

• It helps us understand the current state of the universe.

• It allows us to see the galaxy as it was two and a half million years ago.

• It shows us the galaxy as it will be in the future.

What does the Hubble Deep Field image primarily contain?

• Over 3000 different galaxies.

• Asteroids and comets.

• Nearby nebulae.

• Planets and stars.

What principle is supported by the uniformity observed in deep-field photographs?

• The anthropic principle.

• The principle of uncertainty.

• The cosmological principle.

• The principle of relativity.

Why are space telescopes like Hubble preferred over ground-based telescopes?

• They are cheaper to build.

• They can be easily repaired.

• They are closer to the stars.

• They are not affected by Earth's atmosphere.

What is a major advantage of the James Webb Telescope over Hubble?

• It is designed for planetary exploration.

• It will be launched sooner.

• It has a smaller mirror.

• It can observe more distant objects.

What challenge does Earth's atmosphere pose to telescopes?

• It increases the telescope's range.

• It enhances image clarity.

• It makes telescopes more durable.

• It causes turbulence and light noise.
