Petty concerns, science ain't got time for that.
Science wisdom. It's so satisfying.
Now crack your brain on these things.
Aka suns that turn into black holes
A star that's up to 200-ish times as HUGE as our sun exploded into a supernova. Its name is SN 2006gy (catchy!), and it's 240 million light years away.
THE SHAPE OF THE UNIVERSE
Aka is it a sphere, does it look like a saddle, or is it flat and infinite? It's bigger than what we see, which is ALREADY a lot.
All of our images of the observable universe look like we're in the middle, but we aren't. Matter of possible-fact, there probably ISN'T a middle.
According to NASA, scientists know that the universe is flat with only about a 0.4 percent margin of error (as of 2013). A flat universe is an infinite universe; thus the size of the universe is infinite.
Aka maybe our universe isn't even the only one!
Infinite universes, bubble universes, parallel universes, daughter universes, mathematical universes. They could ALL be possible. If infinity wasn't enough for you, think about the multiverse. I can't even begin to wrap my mind around this stuff, so I'm just going to contemplate the vastness.
