Gravitational Waves: Lone Body in Universe

Click For Summary
A heavy body generates gravitational waves primarily when it is in motion relative to another mass, as the waves are produced due to changes in its quadrupole moment. In a hypothetical scenario with only one body in the universe, it would not emit gravitational waves because there are no other masses to interact with, and thus no changing quadrupole moment occurs. The discussion emphasizes that gravitational waves are not emitted simply by having mass; they require specific conditions of movement and interaction. The rate of gravitational wave emission is significantly higher when a heavy body is near another body compared to when it is isolated. Overall, the presence of other masses is crucial for the generation of gravitational waves.

An heavy body near other body gives off gravitational waves at a higher rate than when it is away from any body.
So, if there is only one body in the universe and nothing else.Will it give off the gravitational waves and it's mass will keep decreasing?

Where did you get this idea? Bodies don't just generate gravitational waves. They have to have a changing quadrupole moment.
 

Thread 'EPR revisited'

In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
