RE: Searching for dark matter with old stones
so dark matter is like neutrinos in the way that its constantly everywhere, it goes through about everything and they are both (so far) undetected but theoretically they make the gaps and the 94% of reality that's missing work
No, neutrinos are detected and observed. Dark matter is not.
but the technique described does remove the need to worry about the background noise, doesn't it ? since they measure trails in the rock that are there , etched for 500 million years, it doesnt matter how many invisible particles and obscure stuff shoots through or near it at the time of examination
There is always some background, and we can always control it to some extent. This yields some error bar on the result.
you mean in this case statistical noise thats "etched" in the same stones together with impact on the core (the nucleus?) and the distance it moved i suppose ? i didnt think of that :)
thats why you're the physicist i guess, thanks a lot for replying every single one again !!!
We are always expecting some background. Some of them can be controlled (i.e. rejected by cleverly investigating what is going on), some of them can't (and his will give rise to some limitations in terms of sensitivity).
with every generation there will be fresh minds who make like paracelsus and tear up the books after reading, come up with new ways to apply old theories or tweak it a little to make it work , and most important, are more able to use whatever is at hand creatively since they were born in the now
thats just how it goes i suppose, we can only hope it happens in our lifetime
or aubrey de grey finds a way :) , thats my mad frankenstein right there
thank you again and have a nice day, -sensei
