Expanding into what?
A great channel for topics like this.
This video goes into the expansion of spacetime as well as cover how internally those forces don’t affect local spacetime because of the mass/spacetime curvature.
Space DOES NOT Expand Everywhere
Although I have to agree with the top comment regarding this being my favorite channel I don’t understand. But the more I watch it the more I start to get a sense of a lot of it and I actually am understanding some of it
And yeah, we don’t know what, if there’s anything, it’s expanding into.
Nothing. It’s the same nothing that existed where we are right now, right at the moment the Big Bang occurred. It’s so nothing, that astrophysicists theorize that time doesn’t even exist there yet.
Look, the universe is big, it has to constantly prove that by being both infinite, expanding, and accelerating that expansion. It used to be very small and now it’s clearly overcompensating.
Time to reverse that insecurity with yo momma jokes about the universe.
- Yo mama so fat that not even light can escape her gravitational pull.
- Yo mama so fat that our galaxy revolves around her.
- Yo mama so fat that when she last farted, they called it the Big Bang.
- Yo mama so fat she’s expanding faster than the speed of light.
Yo mama so fat they stopped the search for dark matter
First two is actually compliments
There are an infinite number of numbers between 1 and 2. Infinite doesn’t mean boundless. So if you had a number line, and you place an infinite number of points on that line, you could then extend that line to be between 0 and 3. There would still be an infinite number of points, but those points would be further apart.
Likewise the Universe is infinte in time and space. There’s always more time, more space, but also the time between points in time can grow and shrink, and the space between points in space can grow and shrink.
The one that gets me is that if the Universe is infinite but how matter can organize itself is finite (albeit a very large number) then there is another galaxy just like ours, another Earth just like ours, and there is another GoofSchmoofer writing this exact some thing in the exact same way somewhere out there.
And if this is true then how many GoofSchmoofer’s are there in this infinite Universe?
