Last night, the two @LIGO detectors observed the second gravitational-wave candidate of the day.
The possible signal with the preliminary designation S250205ee most likely originates – if it is real – from the merger of two black holes.
It occurred at a (luminosity) distance of 9.4 billion light-years.
This brings the total number of significant signal candidates identified in the fourth joint observation run of the international detector network to 190. One (GW230529) has already been fully analyzed and published. The others will also be carefully examined and then published if confirmed.
I have so far taken a conical flask, glass tube, rubber tube and a beaker which is half full of water. The idea being the reaction takes place in the flask, and the Hydrogen is passed in to the beaker to show the gas has been transferred.
As with most things, it is a case of trial and error, when developing what you are doing.
The next meeting of the Tor bay Tinkerers group will be on Saturday 22nd February 2025. Please see their website for more details and a write-up of the May Meeting.
