My heart wasn't really in it, but I was also very discouraged by this.
Photons have a wavelength, and that determins their energy; photons of a same wavelength will all have the same energy; the photons discussed in this article have very short wavelength and very high energy (this energy is proportional to their frequency and inversely proprotional to their wavelength).
Regarding electrons; electrons have mass, and they all have the same mass. They have energy associated with this mass, and they also have energy associated with their momentum, thus they don't all have the same energy.
(except that there's no exception; it's all whatsapp)
Anecodtally, YtM seems to be better for EDM these days; my friends, who are mostly spotify, complain that they're not presented with the same quality and variety of music as I am via YtM. (EDM is just a portion of my tastes, but it's where I have noted a difference in perception between YtM and Spotify).
Sounds like Spotify works for you; if you're finding that "albums you might like" is giving you sufficient good new picks, then why change. If you feel that it's not giving you enough, it might be worth trying YtM (I've been using it for years, and don't know how much that impacts its ability to offer me new music I like, so obviously YMMV).
My understanding is:
1. there needs to be somewhere to escape to, for the schwarzschild radius to make sense, and there's no "outside" to the universe
2. we don't know how big the universe is or what it looks like; if it's infinite and uniform then there won't be any central point for a singularity
3. as others have mentioned, inflation is a get-out-of-black-hole card
4. the physics of the early universe aren't necessarily the same as physics now
e.g. for #2 wave/partical duality (which isn't necessarilly even a thing, depending on what foundation of QM you subscribe to) he says that everything is energy and that energy is light; this is not correct (the 2nd part)
for #3 energy is not necessarily conserved over long time frames in our universe
#4 depends on which foundation of QM you subscribe to, but doesn't necessarily require non-locality (AIUI, if your foundation results in this problem, then you must chose between locality or reality to explain things - reality in this context not really meaning what it might mean in common parlance)
#5 singularities appear in black holes because the maths breaks down because we don't have a unified theory of QM+gravity; they aren't magical. Also the big bang wasn't a singularity in the way he seems to be implying, again AIUI
I'm no expert, but I would suggest you review some more technical videos before reading too much into the link you posted (I suggest PBS Space Time / FermiLab / Sabine Hossenfelder)
There's a couple that I know of:
https://www.goodreads.com/series/40821-belisarius https://www.goodreads.com/search?q=safehold&qid=
Flint was involved in the Belisarius series (along with David Drake), and Safehold is basically Weber's "reboot" of one of the books in his "Armageddon Moon" series.
If you liked 1632 you will probably like these as they're in a similar vein
Additionally, the tours have two sections - the first half that everyone does, and then they offer you the choice of going back up, or going to the museum area; definitely worth spending the extra time (particularly as it seems few people actually do it, so you'll have a chance to actually speak with the guide in more depth).
I've been twice and would happily go again - couple years ago now, so maybe things have changed.
I really should curate my photos - I took hundreds :)
As I understand it, the issue was whether or not you could count a pizza towards your vegetable quota. The argument came down to the nutritional content of the tomato sauce on the pizza; nutritionally, this was very similar to the requirements for other things that can be classified as vegetables, and so one portion of pizza was deemed to also count as one portion of vegetables.
If you were able to do so, yes you could "get" anywhere in zero subjective time - as mentioned earlier, since no time passes for you, there would be no way for you to decide that you wanted to stop travelling at light speed - you would end your existence by impacting something.
> that certainly makes no sense to me
Humans, as a species, aren't experienced with relavitistic effects; we have no useful inherent intuition as to how things behave at these sorts of speeds. Most of us have to accept the maths and the experiements that demonstrate that our understanding of this behaviour is accurate.
Obviously, given that, you would have no way of stopping, so your arrival would be abrupt (ignoring whatever magical affects would be necessary to accelerate a massive object to light speed).
I've not read the books, but I have read the synopsis, and when I read this bit I was somewhat surprised as there are so many things that break that new limit - would our electrical minds work at that speed? What would happen to electron orbitals? What happens to the stars orbiting the galaxy at ~200km/s ?
> The SEC has a three-part mission — to protect investors, facilitate capital formation, and maintain fair, orderly, and efficient markets in between them. We focus on financial stability as well. But at our core, we’re about investor protection.

I have aphantasia, so it's a little more abstract for me, but I can still walk around spaces and pin concepts to them :)
> Later, I store "memories within the memories"
This is such a good idea - I had been thinking about many many different points in a single palace, which is a lot of work; this would make everything much more manageable.
thanks again
> So I memorized books. Convert a book into 100-250 bullet points, memorize them in a memory palace
do you have one palace per book? Many bullet points per location? Very big memory palaces?
do you memorise as you read, or do you take notes and learn those?
any guides that you found particularly useful?
