Exploring the Universe's Timeline and Future

The video explores the future of the universe, starting from the big bang to the potential end. It discusses the changes in the solar system, the sun's lifecycle, and the impact of the Andromeda galaxy's collision with the Milky Way. The video also covers the long-term cosmic evolution, including the fading of stars and the universe's expansion, highlighting the eventual isolation of galaxies.

What is one of the main challenges in predicting the future of the universe?

• The speed of light

• The unpredictability of cosmic events

• The lack of technology

• The vastness of space

What is a significant consequence of the Moon moving away from Earth?

• Increased solar activity

• Longer days on Earth

• More frequent eclipses

• Stronger magnetic fields

How do astronomers use historical records to understand Earth's rotation?

• By observing planetary alignments

• By measuring fossil layers

• By studying eclipse records

• By analyzing ancient star maps

What will happen to the Sun in about 7 billion years?

• It will shrink into a neutron star

• It will enter the red giant phase

• It will explode as a supernova

• It will become a black hole

What is a potential future challenge for life on Earth due to the Sun's evolution?

• Decreased solar radiation

• Increased distance from the Sun

• Runaway greenhouse effect

• Formation of new planets

What will the Sun become after it sheds its outer layers?

• A neutron star

• A red giant

• A white dwarf

• A black hole

What is the term used to describe the matter that makes up a white dwarf?

• Normal matter

• Dark matter

• Degenerate matter

• Antimatter

What is the expected outcome of the Milky Way's collision with the Andromeda galaxy?

• Formation of an elliptical galaxy

• Creation of a new solar system

• Formation of a spiral galaxy

• Destruction of both galaxies

What will happen to the visibility of galaxies outside of our own in the distant future?

• They will become invisible

• They will remain the same

• They will merge with our galaxy

• They will become more visible

What percentage of stars that will ever exist have already been born?

• 50-60%

• 70-80%

• 100%

• 90-95%
