Well the probe was launched in 1998.

Wow I can't believe I didn't realize this earlier.

As a kid I learned of the big bang as an explosion like a supernova. Pretty sure every layman thinks of it like that, yet I kept this understanding even after learning about cosmic background radiation, higher dimensions, expansion, etc. Wasn't till an hour ago that something caused me to think about it and realise what we learn as kids is wrong.

The universe was always infinite in size and practically infinite in energy at every single area. The big bang was more like a big stretch, where the infinite universe expanded and decreased density. No explosion

Now for my personal line of probably incredibly flawed thought, I wonder if the universe has cycles like stars. The initial state of the big bang sounds a heck of a lot like the eventual heat death of the universe, just with a different density value. It seems reasonable that before the big bang a super high energy low entropy state could have existed that slowly evened out, and a super low energy high entropy state could form after the heat death, with new physics emerging at every transition. All our forces were originally combined during the first moments. IDK, it's always fun thinking about this stuff before bed.
