3. The spacetime diagram shows four supernovae events at A, B, C, and D. These supernovae are obscrved on the Earth (system S) and on a fast moving spaceship (system S'). Note that the worldlines of the Earth and spaceship start at (x,t) = (x',1') = (0,0). Answer the following questions: a. In which chronological order do the supernovae occur in the Earth frame of reference? b. In which chronological order do the supernovae occur in the spaceship frame of reference? c. In which chronological order do astronomers on Earth see the supernovae? d. In which chronological order do observers on the spaceship see the supernovae? e. Is the chronological order in which supernovae A and B occur the same in all frames of Explain. reference?

Distances to very remote galaxies are estimated based on their apparent type, which indicate the number of stars in the galaxy, and their measured brightness. Explain how the measured brightness would vary with distance. Would there be any correction necessary to compensate for the red shift of the galaxy (all distant galaxies have signi?cant ted shifts)? Discuss possible causes of uncertainties in these measurements.
Construct Your Own Problem Consider a star moving in a circular orbit at the edge at a galaxy. Construct a problem in which you calculate the mass of that galaxy in kg and in multiples of the solar mass based on the velocity of the star and its distance from the center of the galaxy. Figure 34.26 Distances to nearby stars are measured using triangulation, also called the parallax method. The angle of line of sight to the star is measured at intervals six momma apart, and the distance is calculated by using the known diameter of the Earth's orbit. This can be done for stars up to about 500 ly away.
Distances to the nearest stars (up to 500 by away) can be measured by a technique called parallax, as shown in Figure 34.26. What are the angles 1 and 2 relative to the plane of the Earth’s orbit for a star 4.0 by directly above the Sun?

While working with part of a research team you discover a set of exoplanets in a nearby star system. One of the planets is much closer to its mother star than the other and because of this you are able to determine the average radius of the closer planets orbit to be 37.26 x 10 to the 6 kilometers the Planet complete one orbit every 53.4 days. a) what is the mass of the star in this system?
Part 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…
