Don't Look Now but...


Excuse my double post today - but this is truly exciting and maddening and awesome.

An article came out today arguing that by observing dark matter, we have determined the fate of our cosmos - and that we have inadvertently caused the end of of the known universe.

This works because of the laws of quantum physics - basically everything on a subatomic level exists in a state of possibility. Basically a subatomic particle might be an apple, an orange or a diesel submarine, but it is also none of those things until you observe it. Then, let's say you observe it as an orange - it will forever be an orange. (As a super tangential side note, proponents of the multiple universe idea would say that in other universes that particle will exist as an apple or a sub.)

So... what scientists are now arguing is that dark matter was, like everything in a quantum state, not a "sure thing" until we observed it - and by observing it we have now made it fact.

And now the universe will decay and expand until it grows cold and dies.

We as humans seem to have a whole lot of power. Doesn't it give you a little rush knowing how much of the universe seems to be determined by our ability to observe it? Kinda lends to the idea that each of us are gods in our own right - creating on the go.
