Can you please help me with this question?
A person is flying through space with person B exactly 186000 miles behind. When person A wants to accelerate, he uses a flashlight to signal person B.This means they accelerate together and remain exactly 186000miles apart. Person A wants exactly 1 sec to allow light to reach Person B before he accelerates, so they remains 186000 miles apart from their perspective. What observation will a person standing on ground make?
