(Gravitons) travel at the speed of light (confirmed to an extraordinary degree of precision during the collision of two neutron stars).

What was confirmed? Our telescopes and measuring instruments operate by photons and electrons in the light speed Co dimension. So the high degree only shows us the interactions at the speed of light C.It was observed that a pair of neutron stars collided, with an estimated distance of 130 million light-years away from Earth.
- It was initially detected by gravitational waves; that alone shows that gravitons have an enormous range
The last 100 seconds of the death spiral was observed with gravitational waves.
- 1.7 seconds after the collision ringdown, a gamma ray burst was observed by satellites (gamma rays are a high-energy form of light)
- given the direction, it is assumed that this was from the same event.
- If so, the gravitational waves and light waves arrived together: within 2 seconds out of 130 million years: an extraordinary level of precision for a single measurement!
- That was the basis for my claim that gravitational waves (made of gravitons) travel the same speed as light waves (in a vacuum)
- And hence that gravitons have an infinite range
I agree that our telescopes operate by photons, which is why a long-distance race between photons and gravitons produces compelling evidence that it was effectively a dead heat: gravitons travel at the same speed as light.
Now if you say that there is another kind of light that travels faster than light (only we can't detect it), then I wasn't comparing the speed of gravity to this unknown and undetectable form of light.
- I was only claiming that gravitons travel at the same speed as light = C
