God is mad

I guess

gravitons are different from gravitational waves - both move more fast
than light

if space is expanding - gravitons and gravitational waves will have a
decrease of wave length as they travel through expanding space - they
may have a decrease of energy because of this

expanding space may create gravitational waves

expanding space around mass may create gravitational waves

gravitational lense may focus gravitational waves

gravitational waves can leave a black hole - to an extreme a black hole
can focus gravitational waves - graviational waves can travel a small
distance from center of black hole

gravitational waves associated with Olber's paradox - intensity of
gravitational waves not decrease as distance increases

there are an almost infinite number of gravitational waves - they have
interference - there is constructive interference and destructive
interference - pattern through universe

constructive interference may help people see them

gravitational waves can have entanglement
