Everywhere was not an infinitesimal point, if the present Universe is infinite (as it seems to be). In this case, the Universe was already infinite at the very first meaningful instant of time.
Also, the dark ages explanation is mistaken.
From time 0 to 370,000 years: there were a bunch of short lived photons, but the Universe wasn't transparent to light. After a while, recombination and decoupling ended and this source of light ceased to exist, making the Universe dark again.
Only after ~200 million years the first generation of stars appeared, which we cannot hope to see with a telescope. The first proto-galaxies (too faint) and galaxies took even longer, hence this billion years of darkness.
According to the main view, dark matter floats throughout the galaxy (and outside) but is much more concentrated near the center. A tiny amount is probably crossing your body right now, but there's no way to feel it except for the minuscule gravitational force coming out of nowhere.
We are the center of the Universe. Of our observable universe, at least, by definition. And the total Universe might be much bigger, potentially infinite [or even smaller than the visible universe!]. Even if finite, the Universe would have no center. It's different from a finite amount of matter forming a sphere within an infinite grid, but much like a spherical surface that has no center (the sphere does, the surface does not).

Yes, an alien in a very far away galaxy would see a similar picture. If they are within a few billion light-years, they would see a younger red-shifted Milky Way.
SSR always means outputting the first html as seen from the user when the app is fully loaded and ready to be interacted with. A SPA usually starts with a minimal, blank html file and a huge JS file that mounts the DOM structure and then the user can see something. SSR does the exact same thing, but on the server. From the user perspective, SSR seems faster. From a SEO perspective, SSR is better because there's some initial content on the page.
Not only we, but pretty much no one in the field. If you think about it, everybody got it all wrong, even the shape of the so called curve that was supposed to be flattened, the real number of cases, the mortality rate, the useless power of lockdowns in big countries, etc.
The integers HAVE fewer subsets than the reals!
Cantor's theorem tells us that the power set of any set has more elements than said set. It's also well known that the reals have the same cardinality as the power set of the integers.
Therefore, |P(R)| > |R| = |P(N)| > |N|, so the power set of the reals has more elements than the power set of integers.
The continuous hypothesis is the belief that no cardinal exists between |N| and |P(N)|. My previous argument fails if we pick two sets A and B, such that |A| < |B| < |P(A)|.
This can be done, depending on the window manager.
In my awesome window manager setup, super+tab always toggle the last 2 windows on the current tag (workspace). It's also possible to map super+1 to make an application be part of the current workspace (or open a new instance there). In this model, a window can be part of more than 1 workspace at the same time.
