Planet 9 Could Be a Black Hole! SciShow News

The video explores the Planet 9 hypothesis, suggesting a Neptune-sized planet or a primordial black hole could exist in our solar system. It discusses the potential for detecting such a black hole through gamma radiation. Additionally, it covers a recent tidal disruption event where a black hole tore apart a star, providing insights into black hole behavior and stellar dynamics.

What led scientists to propose the existence of a ninth planet in our solar system?

• Changes in Earth's orbit

• The reclassification of Pluto

• Unusual orbits of small bodies

• Discovery of a new star

What is a primordial black hole?

• A hypothetical black hole formed shortly after the universe began

• A black hole formed from a dying star

• A black hole that emits visible light

• A black hole that is larger than the sun

How might scientists detect a primordial black hole?

• By measuring gravitational waves

• By observing visible light

• By tracking changes in Earth's magnetic field

• By detecting gamma radiation from dark matter interactions

What is a Tidal Disruption Event (TDE)?

• A star being pulled apart by a black hole

• A planet colliding with a star

• A black hole forming from a supernova

• A galaxy merging with another galaxy

Which instrument first detected the Tidal Disruption Event discussed in the video?

• NASA's TESS

• Hubble Space Telescope

• James Webb Space Telescope

• Chandra X-ray Observatory

What was the significant temperature change observed during the Tidal Disruption Event?

• From 50,000 to 25,000 degrees Celsius

• From 10,000 to 5,000 degrees Celsius

• From 40,000 to 20,000 degrees Celsius

• From 30,000 to 15,000 degrees Celsius

Why is the study of black holes and TDEs important?

• They are the only way to detect dark matter

• They offer opportunities for new discoveries and improve our understanding of cosmic phenomena

• They provide insights into the behavior of galaxies

• They help us understand the formation of planets
