“In space, no one can hear you scream.” “In space, no one can hear you scream.”
It’s been reported that under certain conditions sound can skip across a vacuum. I’m not saying this is what they were referring to with ‘gravitational thunder”, but it is interesting.
I'd like to see that study/experiment.
In a vacuum, only if the source and destination are in physical contact, by way of some sort of matter, can sound waves propagate.
After watching the video, the 'gravitational thunder' is explained. The sound is created by a computer that has been fed digital data that is created by the reception of weak gravitational disturbances...or waves if you prefer.
