Physicists don't even know why it started expanding to begin with. We also don't know if there's anything outside of our own universe. We also don't know if our universe is curved and folded in on itself, which would make several mathematical calculations for the size of the universe and what was going on with expansion a bit easier to try and work out (I'm also not a physicist. These are just things ive read about) or if it's flat. Their best measurements right now is that it's flat. But they still aren't sure, because they don't know how big space actually is right now. If it's big enough, it could still be curved in on itself, but we just can't measure the flatness of two points far enough apart from each other to notice the curve. An example I given was that it would be like trying to show the earth was round by measuring an area of a sandbox.

There's no evidence to point to the big bang as being the very beginning, though. There may well have been a billion big bangs before this one. Each one taking so long to reset and start anew that to us, it might as well be seen as about infinity. Humanity outright doesn't have the knowledge of what happens on extremely large or extremely small scales. We don't really have a clue for what actually made space start to expand in the first place, so we don't know if it's ever happened before, or even if it happened anywhere else at any other time but outside of our observable universe.
What makes anyone think "the big bang" has only happened once?
They keep finding inconsistencies to that. Groupings and radiation and gap distances that don't line up with the expansion expectations.
Then the other more applicable point is that what makes you think "the big bang" was the first big bang? You think mass and entropy and radioactive decay and all this shit in the nothingness of space all started with "the big bang" but it only happens once and then in a ridiculously long time from now when everything reaches absolute 0 and there's no energy left anywhere, that it's just done? A one trick pony?
Well what if it all eventually manages to head back to its origin point after that and it makes another big bang that kicks off again?
But the speed of light changes. It can be slowed down. It just doesn't change while moving through outer space (a vacuum). The maximum speed is the constant.
No they aren't. They degrade before they fail. If tesla wanted to provide a warning of a failing battery that pretty much always worked it could have wired in a load test and went off voltage drop under a heavier load.
Testing if batteries are good or bad does not qualify a person to chart out battery degradation.
What? No they aren't. They almost always fail on a curve of power and voltage loss.
Also, I didn't look it up, but I'd be very surprised if the model Y tesla didn't require (suggest and oem?) an AGM battery. It's still lead, but due to how they're made they can't get a dead short in them like older regular lead acid batteries can once they get old, although it still isn't very common for it to happen.
That's nonsense. You think some massive amount of matter just materialized from nothing into a singular point? How do you think all the stuff managed to get there in the first place?
Can time really exist if there was no frame of reference to measure it? We can only detect it by motion or entropy. It's the only way of "time". So if there was some point where there was nothing that moved, then time wouldn't exist.
For that matter, there's no way of measuring if time is even consistent. If it were constantly speeding way up, or slowing way down, we'd have no way of knowing.
Time is just a figment of our imagination so we can keep track of movement. Just like magenta isn't a real color.
That's the one. I heard wedding venues started spreading the rice thing because they were sick of cleaning up rice and bird shit all the time.
I'm guessing the other just got popular for farm kids wanting to fuck with city folk.
"Cow tipping" and "uncooked rice killing birds" have got to be the two biggest and most successful trolls of all time.
What I meant by "what if it wasn't the first big bang?", was that what if it wasn't the first of our own universe? I mean what if space will at some point stop expanding and start contracting. Pull everything back close together again. Then theres another expansion just like what we're currently in now. The best scientists, physicists, and mathematicians haven't been able to work out a lot of major thing about our universe or how it works or even if it's flat or folded in on itself yet. The data and tests/measurements don't exist yet. So until that can get worked out into a theory, it's silly to say time began at the expansion.
