Where Did the Big Bang Happen?

The video explores the universe's nature, starting with the Big Bang theory, which describes the universe's rapid expansion from a hot, dense state. It explains how galaxies appear differently based on their distance and the time it takes for their light to reach us. The universe's structure, influenced by gravity, forms filaments and voids. The Hubble constant measures the universe's expansion rate, defining the observable universe's limits. The cosmic microwave background provides a glimpse into the universe's early state, offering insights into its history and structure.

What is the Big Bang theory primarily about?

• The formation of stars

• The expansion of the universe from a hot, dense state

• The creation of galaxies

• The end of the universe

Why do distant galaxies appear younger to us?

• They are smaller in size

• They are actually younger

• They are moving towards us

• Their light takes a long time to reach us

What does the Hubble constant describe?

• The age of the universe

• The size of the universe

• The rate of the universe's expansion

• The speed of light

How does gravity affect the universe's expansion?

• It reverses the expansion

• It slows down the expansion

• It has no effect

• It accelerates the expansion

What is the observable universe?

• The part of the universe we can see

• The universe beyond the speed of light

• The universe's center

• The entire universe

What is the cosmic microwave background radiation?

• Radio waves from galaxies

• Visible light from stars

• Infrared radiation from planets

• Microwaves from the early universe

Why can't we see beyond the cosmic microwave background radiation?

• It is too far away

• There are no galaxies beyond it

• The universe is too dark

• Light couldn't travel through the early universe
