RE: Searching for dark matter with old stones
I got as far as understanding they reduce the cost by a magnitude of several zeroes by removing the need to shelter from this cosmic background, and that is why detectors are built deep underground (leave me asking the same as those neutrinos though, if a ray can pass through the planet whats the point of a few kilometres of rock in between ? does that REALLY help ?).
Neutrinos will interact too and leave track too. But this is even more rare than dark matter.
where does the dark matter come in to play here, thats not completely clear ?
Dark matter travels within the universe, and dark matter is supposed to constantly go through Earth.
you don't have any mad frankenstein geneticists in your #steemstem team you could recommend by any chance?
Mmmhhh... try @mobbs :D
@mobbs ... #steemstem manager from China ...
topmost post the history of death by sawing
yea i think we could probably get along,
thank you for the directions
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
it's like the more i understand the less i get it :p
but i'm not one to quit something i chose to do , thank you again for taking time, i hope you're enjoying the summer a bit , can't always be strung up (sounds bad literally translated hmmm)
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
once again pardon my lack of scientific lingo, im actually quite amazed i could make out the meaning of that paper, its a bit of a problem googling these things, you often get links to places like Cornell and those papers arent really written for the people, are they ?
much obliged
No, neutrinos are detected and observed. Dark matter is not.
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
