TED-ED: How small are we in the scale of the universe? - Alex Hofeldt

The video discusses the Hubble Telescope's observation of a dark sky area near the Big Dipper, capturing over 1,500 galaxies in a tiny universe sliver. It explains the scale of this image, comparing it to cosmic distances and the size of celestial bodies. The eXtreme Deep Field image, a result of over ten years of photographs, reveals galaxies so distant they're barely visible to the human eye. These images act as time machines, allowing scientists to study galaxies from over 13 billion years ago, shortly after the Big Bang. The video highlights the universe's homogeneity and encourages viewers to ponder the vastness of space.

What was the significance of the area near the Big Dipper for the Hubble Telescope's first Deep Field image?

• It was a region with known galaxies.

• It was the closest area to the Earth.

• It was a dark area with minimal light pollution.

• It was a well-lit area with many stars.

How many galaxies were observed in the Hubble's first Deep Field image?

• 10,000

• 100,000

• 1,500

• 3,000

What is the eXtreme Deep Field image known for?

• Showing the closest galaxies to Earth.

• Capturing galaxies that are extremely distant and faint.

• Displaying the largest stars in the universe.

• Focusing on the Milky Way galaxy.

What do the Deep Field images reveal about the universe?

• The universe is chaotic and unpredictable.

• The universe is homogeneous across vast distances.

• The universe is mostly empty with few galaxies.

• The universe is shrinking over time.

What does the study of the Deep Field images allow scientists to research?

• The future of the universe.

• The core of the Earth.

• Galaxies in their infancy.

• The surface of the Sun.
