The safari has just watched a snippet about the hunt for dark matter. Will someone help me out here. Deep seep underground there is a machine that is looking for the fainest hint of a dark matter. But then the chap said it might not actually exist, then he went on to explain that 'theoretically' it has to exist otherwise the universe wouldn't work due to lack of mass for the observed gravity.
How can you build a machinr to detext something that might not exist? how would you go about calibrating it?
Good job I'm an ecologist bot an astro-physist - eh...but always willing to learn...or at least try to understand...
In the meantime if you've come across a blob of dark matter in your outback please let those underground guys in Middlesborough know. Good birding up that way...and birds are way easier to find than the dark stuff.
BTW - I don't have a pic of any dark matter for you this evening.
