Do cosmologists know for sure that the Big Bang is propelling all matter away? (lemm.ee)

Is it at all possible that instead of being pushed away, we are instead getting pulled toward something huuuuuge via gravity? As if we are falling into something way greater than ourselves? I thought this was a wild idea but after I Googled it I found out that there is such a thing as a “Great Attractor”. Something 150 million light-years away is literally pulling all nearby galaxies towards it but no one knows exactly what it is.

So how do we know there aren’t any other Great Attractors, Greater Attractors, ad infinitum?

unfortunately, it’s on the other side of the Milky Way, so we can’t see it.

The thing that blows my mind is that, Gigantosaurus could (have; but Plesiosaurs couldn't). This more than any other fact illustrates the enormous time span of the dinosaurs' rule.

We are closer to the extinction of the T-Rex than the T-Rex was to the extinction of the stegosaurus.

You do know that only some of the dinosaurs died and one large lineage is still alive, right?
