- Calculate the redshift caused by a neutron star with a radius of 11 km and mass of 5.2 x 1030 kg.You discover by dropping particles into it that the Event Horizon (Schwartzschild Radius) of a black hole is 171 km. How massive is it? (enter just the number in solar masses)Why are gravitational waves so difficult to detect?
- The biggest black hole ever discovered has a mass of 40 billion solar masses. Calculate the Schwarzschild radius and compare it with the size of our Solar System.A spaceship is located around 2.6×10¹³ km from the black hole Messier 87. It has a mass of 6.6 billion suns. How long will their day last compared to a day on Earth?Event Horizon is a region around a black hole where: group of answer choices: even light cannot escape. all the events are occurring speed of an object is close to speed of light. no physical object can pass through. r nothing can enter .
- Calculate the Schwarzschild radius of the Sun.The area of the event Horizon of a black hole is 4tRg². Use the Schwarzschild metric to verify this. (Please answer in detail or skip)Calculate the gravitational redshift of radiation of wavelength 550 nm (the middle of the visible range) that is emitted from a neutron star having a mass of 5.8 × 10³⁰ kg and a radius of 10 km. Assume that the radiation is being detected far from the neutron star.
