I have this question on my homework, and i dont know the answer...im hoping someone here can help me out
What explanation does general relativity provide for gravity? 1. Gravity is inversely proportional to radius. 2. Gravity is directly proportional to mass. 3. Gravity is a result of curved spacetime. 4. All of the above
thank you so much, i was also curious about the lighthouse model of a pulsar is it true that the period of pulsation must speed up as the neutron star continues contracting?
