Neutrinos are created as a result of certain types of radioactive decay or nuclear reactions such as those that take place in the Sun, in nuclear reactors, or when cosmic rays hit atoms. There are three types, or “flavours”, of neutrinos: electron neutrinos, muon neutrinos and tau neutrinos; each type also has a corresponding antiparticle, called antineutrinos. Electron neutrinos (or antineutrinos) are generated whenever protons change into neutrons (or vice versa), the two forms of beta decay. Interactions involving neutrinos are mediated by the weak interaction.
[I was once offered a PhD at Oxford in muon spin-resonance]
Most neutrinos passing through the Earth emanate from the Sun, and more than 50 trillion solar neutrinos pass through the human body every second.
By the time you read this it’s a lot more than 50 trillion. And you bought your book by Émile Durkheim why precisely? We are out in the suburbs of the Orion Spur, 8,000 parsecs* from centre and there are of the order of 100 billion stars in this galaxy and you are “studying” media! Why?
I think it’s time to go down-town and check out the action – don’t you reckon?
There is a triple breasted lady with green skin that I want to take roughly from behind. I mean if Captain Kirk did it then why not me?
A few years ago this was stetted. That is Skylon and it needed 180 million that a government (cheers Ruth Kelly you obnoxious muntrix!) couldn’t afford that but could afford to bung Muslims half that to not be nasty.
My hero, Clarence “Kelly” Johnson believed that if it “looks right it will fly right”. That looks like a spaceship to me. Because that is so cool!
Request for funding from the British government was undertaken in 2000, with a proposal that could have offered a large potential return on investment. The request was not taken up on at that time. Subsequent discussions with the British National Space Centre led to agreement in 2009 on a co-funding agreement between BNSC, ESA and REL to continue technology development for the SABRE engine.
That’s a variable cycle engine. That is faster than the flying fuck.The Sabre will do Mach 5.4 air breathing. And then when the LOX kicks in above 26 km to it’s orbital flight it will go very, very fast indeed and that is really fast. That is Mach 20+ which is absolutely fucking caning it. Why could we not afford that?
Just build Skylon and open Bristol International Spaceport and let me go home.
*A Parsec is about 31 trillion kilometres or 3.26 light years. You might think it’s a long way to the post office but that is fuck all to what is out there.
