Was the Milky Way a Quasar?

The video explores the Milky Way's relatively calm state compared to its past and other galaxies. It discusses the discovery of Fermi Bubbles, massive gamma-ray structures, and explores theories about their origins, including supernovae and black hole activity. Recent studies suggest the Milky Way's central black hole, Sagittarius A*, may be more active than previously thought, with implications for future cosmic events.

What is the current state of the Milky Way compared to other galaxies?

• It is relatively calm compared to many other galaxies.

• It has no black holes at its center.

• It is the most violent galaxy in the universe.

• It is more active than most galaxies.

What did astronomers discover using the Fermi Gamma Ray Space Telescope?

• A new planet in the Milky Way

• A pair of high-energy gamma ray bubbles

• Evidence of life on Mars

• A new type of star

What are the Fermi bubbles?

• Clusters of new stars

• Diffuse clouds of gamma rays

• Massive pair of high-energy gamma ray bubbles

• Regions of dark matter

Which two main theories are proposed for the origin of the Fermi bubbles?

• Black holes and neutron stars

• Quasars and pulsars

• Supernova explosions and activity from Sagittarius A*

• Dark matter and cosmic rays

What is a starburst event?

• A new galaxy formation

• A black hole explosion

• A type of supernova

• A sudden increase in star formation

What is the most likely explanation for the formation of the Fermi bubbles?

• A collision with another galaxy

• A combination of AGN activity and starburst events

• A single supernova explosion

• Dark matter collisions

What recent discovery supports the combined theory of AGN and starburst events?

• A decrease in gamma ray activity

• New planets in the Milky Way

• Radio bubbles similar to the Fermi bubbles

• A new type of black hole

What recent activity has been observed from Sagittarius A*?

• A new star formation

• An increase in X-ray activity

• A decrease in X-ray activity

• A supernova explosion

What is the potential impact of increased X-ray activity from Sagittarius A*?

• Creation of new Fermi bubbles

• Destruction of the Milky Way

• Formation of a new galaxy

• No significant impact

What protects Earth from the gamma ray radiation from the Fermi bubbles?

• The Sun

• The Milky Way's magnetic field

• The Earth's atmosphere

• The Moon
