I know some may argue this doesn't belong on /x/, but I think many theories could be metaphysical or unnatural.
What do you think Dark Flow could be?
The fact that there is something so massive that it's pulling every in our visible universe towards it, yet it's so distant we cannot see it.
When I think about interesting/bizarre things, I'm always draw back to Dark Flow (pun accidentally intended).
The Universe is weird. We exist as meatsuits clinging to an exploding rock which orbits a giant ball of fire.
Physics is a rabbit hole. Dark Flow will probably be the result of bad math or anomaly, there are bigger questions to ask.
Multiverses are probable. It's also probable that some species will eventually merge with machines and create a different state of consciousness. It's also probable that the omnipotent AI which Google are creating will eventually deem humans useless and wipe us from the planet.
Guess it's not /x/ relevant. :/
