Too Strange to Be True? Despite strong theoretical arguments for the existence of neutron stars and black holes, many scientists rejected the possibility that such objects could exist until they were confronted with very strong observational evidence. Some people claim that this type of scientific skepticism demonstrates an unwillingness on the part of scientists to give up their deeply held scientific beliefs. Others claim that this type of skepticism is necessary for scientific advancement. What do you think? Defend your opinion.

Which statement concerning black hole masses and Schwarzschild radii is not true?
A. Even an object as small as you could become a black hole if there were some way to
compress you to a size smaller than your Schwarzschild radius.
B. The more massive the black hole, the larger the Schwarzschild radius.
C. For black holes produced in massive star supernovae, Schwarzschild radii are typically a
few to a few tens of kilometers.
D. In a binary system with a black hole, the Schwarzschild radius depends on the distance
from the black hole to the companion star.

A, It emits X rays characteristic of an accretion disk, but the unseen star in the system is too massive to be a neutron star. B. No light is emitted from this star system, so it must contain a black hole. C. The fact that we see strong X-ray emission tells us that the system must contain a black hole. D.Cygnus X-1 is a powerful X-ray burster, so it must contain a black hole.arrow_forwardWhat is the point of view on the topic of parallel universes and black holes?

- Perhaps the most fundamental problem in all of astronomy is the determination of distance to the various objects in the cosmos. Which of the following seems least reasonable regarding the various measurement techniques: Group of answer choices The Hubble Law relates the recessional speed of distant objects (measured with the Doppler Effect) to distance. Hubble law is most useful for determining the distance to nearby objects, while parallax is most useful for the more distant objects. We can determine the position of a star on the H-R diagram through spectral analysis and then figure out the distance by comparing absolute luminosity (from H-R diagram) to apparent brightness. The distance to nearby stars can be determined by measuring parallax. The distance to the planets in our solar can be determined by measuring the time for a radar signal to reach a planet, bounce off, and return.arrow_forwardFalling into Gargantua part I: Why does Gargantua appear the way it does? Because it has two accretion disks, a horizontal and a vertical one. The vertical halo is the light of the accretion disk on the far side lensed by the gravity of the black hole. Because that’s the way the art director wanted. Falling into Gargantua part II: What would Cooper’s view be of the rest of the universe as he falls across the event horizon of the black hole Gargantua? Nothing - he would no longer be able view the rest of the universe He would see the future history of the universe unfold as his field of view shrinks to a bright spot He would observe a time reversed history of the cosmos as his field of view shrinks to a bright spot.arrow_forwardPart 1. Stellar Mass Black Holes These are the collapsed cores of massive stars which end their life in supernova explosions. The stellar core can no longer use nuclear fusion to hold up the immense gravity, and collapses until its escape velocity rises higher than the speed of light. Voila! A black hole is formed. Part A: The Schwarzschild Radius The Schwarzschild Radius is defined as: 2GM (1) = c2 where r, is the Schwarzschild radius, G is the gravitational constant, M is the mass of the black hole, and c is the speed of light. 1. Let's say we have a black hole with a mass 10 times that of the Sun (the Sun's mass is 2 x 1030 kg, so the mass of the black hole is then 2 x 1031 kg). Using the definitions for G and c, what would the Schwarzschild radius of this black hole be? 2. If the radius of the Sun is 7 x 108 m, how does the black hole's radius compare? (Divide the radius of the Sun by the Schwarzschild radius). Your answer should be in the form of times smaller/bigger than the…arrow_forward
