Star Crash: The Explosion that Transformed Astronomy (15min video)
YouTube ^ | 11/13/17

Posted on 11/14/2017 12:17:30 AM PST by LibWhacker

A startling collision in an ancient galaxy slews Earth's largest telescopes to a spot in the Hydra constellation. Two rapidly spinning neutron stars have violently merged to form a possible black hole. And, for the first time, astronomers see its electromagnetic flash and hear its gravitational thunder as they watch new elements being born.

Two rapidly spinning neutron stars have violently merged ...

I don't think there is a gentle way to do this.

I’m literally blown away by that! Fastest 15 minutes I’ve had in years.

hear its gravitational thunder

Um. What?

Thanks for the great video. These simultaneous observations are a tremendous human accomplishment many decades in the making. It’s right up there with landing a man on the Moon.

It’s hard to imagine it’s happening with all the scum in politics, scum in the media, and primitive behavior by some people that we are bombarded with day to day.

“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.

I’ve been wondering about that, too. Gravitational waves are, as the narrator said, “ripples in the fabric of space-time.” They are waves, but they are not electromagnetic waves. They are not light. There is no electrical or magnetic component in a gravitational wave.

Sound can’t move in a vacuum and gravitational waves can’t move in a true vacuum either. But space-time is not a true vacuum. There is a fabric in space and time and gravitational waves make ripples in it as they propagate outward, just as sound makes ripples/waves in air or water, or whatever medium it’s moving through, as it moves outward.

So gravitational waves are much more sound-like than light-like, and they say we “hear” it rather than see it.

Well, that’s just the explanation I came up with in my confused little head to explain to my own satisfaction what the physicists were ‘splaining to us. No idea, really, if it is correct. If it is, the next question is, are these gravitational waves longitudinal in nature (as sound waves are) or transverse (as ripples on a pond are). Keeping with the sound analogy, I’m guessing they are longitudinal.
