Step by step
Solved in 2 steps
- Choose the BEST answer to the following: If a star that is 20 light-years from Earth explodes, gravitational waves from the explosion would reach Earth in (a) less than 20 years. (b) 20 years. (c) more than 20 years. (d) None of these.What is the order of objects to form from first to last after the Big Bang nuclei,neutral Atoms, protons?Would would happen to Spacetime at the surface of the Sun if you kept the volume the same but increased the mass? Spacetime curvature decreases with increasing density. The spacetime curvature would increase with increasing density. Spacetime doesn't respond to increasing mass, only changes in density. Spacetime doesn't change with increasing density.
- The discovery of the dark energy was a surprise because astrophysicists generally assumed that the expansion would be slowing down. Select one: True FalseHow do gamma-ray bursts provide insights into the most energetic events in the universe?How do gravitational waves provide new insights into the universe and our understanding of gravity?
