I was trying to explain to a friend in lamens terms why dark matter is so hard to detect while other weakly interacting particles were a bit easier (like neutrinos). It all comes down to mass.
If you could only interact with an object by blowing on it (an analogy for weak interactions) you could easily influence a fast moving feather (an analogy for a light neutrino). However if it were a bowling ball you can blow on it all you want and it wouldn't be effected at all (an analogy for Dark Matter).
Hope you're all having a fantastic day! Lovely blue skies here in Tel Aviv, a day I'm wishing I could lay out in the sun and just enjoy it. I've got work, unfortunately, but that can be nice, too.
So, #RandomQuestion for today is as follows:
What is a combination of foods you've discovered that maybe isn't standard and might sound a little odd. You gotta love it, though.
I've got a thing for peanut butter and jelly sandwiches on toast with hot sauce.
