Exploring Black Holes in the Milky Way

What is the estimated number of black holes in the Milky Way galaxy?

• 10 million

• 200 million

• 500 million

• 1 billion

What is the primary challenge in detecting isolated black holes?

• They have no nearby objects to influence.

• They move too quickly through space.

• They are too small to detect.

• They emit too much light.

What technique is primarily used to detect isolated black holes?

• Infrared imaging

• Gravitational lensing

• Radio wave analysis

• X-ray detection

What is the role of gravitational microlensing in black hole detection?

• It measures the temperature of black holes.

• It captures the sound waves from black holes.

• It observes the bending of light around massive objects.

• It detects the light emitted by black holes.

What is the estimated mass range of the discovered object by the UC Berkeley team?

• 7.1 to 9.0 solar masses

• 5.0 to 7.0 solar masses

• 1.6 to 4.4 solar masses

• 0.5 to 1.5 solar masses

What is a potential alternative classification for the discovered object if it is not a black hole?

• A white dwarf

• A neutron star

• A red giant

• A brown dwarf

Which team estimated the mass of the object to be closer to 7.1 solar masses?

• Space Telescope Science Institute

• European Space Agency

• NASA

• UC Berkeley

What discrepancy exists between the two teams studying the microlensing event?

• The speed of the object

• The temperature of the object

• The distance and mass of the object

• The color of the object

What is the significance of the discovery of a free-floating black hole?

• It suggests that black holes can emit light.

• It provides a new method for detecting exoplanets.

• It challenges the current understanding of black hole formation.

• It confirms the existence of primordial black holes.

What future observations are planned to resolve the discrepancies in the findings?

• Launching a new telescope

• Conducting a spacewalk to the object

• Sending a probe to the object

• Using the Hubble Telescope for further observations
