While Traveling the Galaxy in a Spacecraft,you and a Colleague

question 25

Multiple Choice

While traveling the galaxy in a spacecraft,you and a colleague set out to investigate the 10⁶M_⨀ black hole at the center of our galaxy.She hops aboard an escape pod and drops into a circular orbit around the black hole,maintaining a distance of 4 × 10⁶ km,while you remain much farther away in the spacecraft.After doing some experiments to measure the strength of gravity,your colleague signals her results back to you using a green laser.What would you see? Hint: you will need to calculate the location of the event horizon.

• A)You would see her signals unaltered in wavelength because she is orbiting well outside the event horizon of the black hole.
• B)You would see her signals shifted to a much redder wavelength because she is close to the event horizon.
• C)You would see nothing because your colleague has crossed the event horizon around the black hole.
• D)You would see nothing because no light can escape the gravitational pull of a black hole no matter how far she is from it.
• E)You would see her signals shifted to a much bluer wavelength because black holes can make highly energetic light.
