    the big bang wasn’t an explosion from a point, it was an explosion of a point in space. That one point is still expanding to this day. Everything is moving away from everything else, which wouldn’t be the case in an “ordinary” explosion. We are all still in that one point, it’s just that that point has expanded. The center of the universe is, in the literal sense of the word “literally”, everywhere.

      Im kinda trollin at this point, but in an ordinary explosion, in a vacuum without external gravity, everything would indeed have a different initial velocity and direction, so everything would be moving away from everything else.

        imagine standing at the side of the explosion looking towards it. some debris will be blown way from you, but some will be coming towards you. You are something, and not everything is moving away from you, some debris hits you in the face. That’s an explosion in space.

        An explosion of space is defferent. Everything will be moving away from you, regardless of where you are or which side you’re facing.

        Something wasn’t in space and it exploded. Space itself exploded. your argument only holds if you are exactly in the explosion source.

        In space, we’re still inside the explosion

          I’ve given up trying to explain it to people as an explosion. Media and innate biases make people view that word as a “kaboom” and form a mental picture.

          I tell people that the universe was likely always infinite. In the beginning it was infinitely dense and essentially a singularity, but that singularity wasn’t a point in space like a black hole, it was a everything and everywhere. The universe was ultra dense, infinite energy, then all at once, the whole thing got bigger like the infinite hotel paradox, an infinite space can get bigger. So all the whole infinite space just stretched out in all directions, making space open up and the energy less dense.
