This is where my mind clash. I believe in science and in space. I recently been digging deeper into it, but to me the more I dig it gets really complicated.It drives me insane to think about it and makes me wonder if it's even real. Space at time makes no sense to me, I know I'm not an astrophysicist but my God man some shit they say doesn't make sense, like how do you know this stuff goes back to the big bang and how are we the only ones alive? How come we've never seen this supposed 9th planet this whole time?

I've been through a few dashboard cameras (Texas sun in a black car w/black interior kills em) and most do get you the ability to record at lower FPS. Security cameras I know do, but my current dashboard cam I've had a couple years and don't remember if it does :(

AKA sunbeams, aka crepuscular rays. If you ever see crepuscular rays when you look at the sunset, turn around and face the opposite direction. You may see dark counterparts, known as anticrepuscular rays. They're the shadows of the clouds causing the sunbeams in the west. Anticrepuscular rays converge on the eastern horizon, opposite the sun's position in the west.

The same holds at sunrise, of course.

But the universe IS the surface. In this example, there is no inside. For an object placed upon the baloon, all that he sees is everything getting further apart, and that's how the universe behaves.

The universe was smaller, than it got bigger. It got bigger everywhere, in all directions, at the same rate. There is no 'X' direction where things got pushed out of, everything just got more distant from everything else.

? The surface doesn't have a center, but the balloon does. If all the mass was on the balloon surface, then there is a point inside the balloon that is, effectively, the center of mass of all that mass. That's X. And, presumably, not ALL of the mass expanded outward, otherwise there would be a massive empty space in the middle of the universe. (As far as I know, that hasn't been discovered.)
