There's some mysterious entity,
beyond the boundaries of our galaxy, that is pushing against us with incredible force.
We don't know exactly
what it is, and we don't know how long it's been there. But we do know its name: the dipole repeller.
The name may be a bit
dorky but it is normal consequence of the usual process of structure formation that's been happening in the universe for [checks watch] 13.8 billion years.
It's actually kind of
hard to map our local vicinity of the universe because all the dust in the Milky Way obscures our view
We have to resort to fancy
astronomical tricks, like sensitive infrared and radio surveys, to get a sense of what's going on.
It's a hypothetical void
that sits on the opposite side of the Milky Way as the Shapley Supercluster. As the Shapley pulls us with its massive gravity, the dipole repeller pushes us with its massive … nothingness.
