Neutrino Traced Back To Distant Galaxy.

What a tremendous thing to have done. Brilliant!

Quite fascinating, hard to get your head round really.

[NoMercy]

Incredible. I wonder what we will have discovered in 100 years' time?

[EDDIE51]

Even more amazing when you know that over 99.999% of Neutrinos pass straight through the entire Earth without being detected. They can only be detected if they hit an atomic nucleus 'head on' which is VERY unusual. Then there is the fact that that neutrino must have started its journey just after the Big Bang, that was the beginning of the Universe. They travel near the speed of light so its journey has taken over 37 Billion years.

Fascinating stuff, it had quite a journey until it bumped into our little rock.

Nice one Togo.

Amazing! I can't even locate a pen when I need one.

The "ice cube" detector is an astonishing bit of kit.

// IceCube was created by using pressurized hot water to melt 86 shafts into the polar ice over a square kilometer. Before the shafts refroze, cables strung with 60 digital optical modules apiece were lowered down so that the modules sit evenly spaced every 17 meters between 1450 and 2450 meters deep//

"They travel near the speed of light so its journey has taken over 37 Billion years."

Since the Universe is only 14 billion years old, the journey won't have taken 37 billion years...

[jno]

it may have gone round the long way, though

[Togo]

Eddie missed out the decimal point Jim. 3.7 billion. Not to say the difference between light years and miles even. :((

[EDDIE51]

Jim 360 yes, but the distance of the Galaxy is given as 37 Billion Light Years away. So I assume it is on 'the other side' of the Universe and receding from us at more than the speed of light?

[EDDIE51]

^ OK that's it. The title says 37bn - light -years-away . Then the actual artical says 3.7 Billion.

[naomi24]

I was reading an article on this earlier. Fascinating.

[Togo]

Lol at Naomi. No chance of you getting your articles and particles mixed up then.

[Old_Geezer]

As it's traveling at the speed of light I'm convinced it's taken it no time at all. It's as young & fresh as it's always been.

[naomi24]

Togo, ?

[Togo]

Check the spellings Naomi. (not yours)

[naomi24]

Ohhhh! Haaaaaaaa!

[Togo]

Just like you then Geezer. :))
