Colliding stars.

The radio has just told me,130 million years ago, 2 Neutron stars collided and the waves from it arrived in August, I will make no comment on the postal service, but they played what they said was the sound of it, it sounded like a wet sort of comical splat. I am not in the slightest convinced. I wonder if this is our future? Do try to hear the sound, it is worth it. Micheal Bentine would have been proud.

Should keep the theoretical boys happy for a while examining the data. Neutron Stars are only one step short in terms of seriously weird than black holes.

Sounded like a party pooper to me ! .. but those things need to be 'far far away in another galaxy' ... don't want them nearby.

From a technical perspective I highly doubt that the collision of two neutron stars actually produced either sound or electromagnetic waves within the audible range.
More likely some enthusiastic physicist wished to try and make the whole event comprehensible to the average person and so mixed the microwaves with another frequency to produce a recognisable 'sound'.

I believe the audio representation was made up of gravity wave variations, not microwaves. These were first predicted by Einstein's General Theory of Relativity more than 100 years ago and have only recently been discovered using the LIGO equipment. To develop gravity waves that are detectable you need phenomena such as neutron stars and black holes.

Space takes a bit of bending.

Perhaps we are only just starting to grapple with the understanding of the incomprehensible amount of energy in the univervse?

I'll remember that next time I want to make waves.......

In the meantime now is the time for the appearance of the Orionids,spin offs from Halley's Comet,which should be around for most of the month.

Still ... the pub is open ...
