Nothin' but Space

STRING THEORY? That's right! In today's episode, we're going over the very ideology that posits our universe existing within a multiverse, along with the many others that also postulate our 4-dimensional brane holding even more dimensions. (Yes, this is real. No, it does not just exist in sci-fi. And yes, it will blow your mind.) So if you've ever thought about how our universe could be a hologram, or wondered if maybe - just maybe - there's an alternate world where you didn't fail that math test, don't forget to tune in today.

Today we're bringing in the big guns - questions about our universe as a whole, including its shape, whether it's finite or infinite, and more. I bet you haven't thought too much about this before, but once you dive in, you can't stop - it's just so cool to envision! Is our universe flat? Spherical? Hyperbolic? And exactly how large is it? To be honest, we aren't completely sure, but I'll tell you where we're at right now . . .

Dark matter - one of the largest space mysteries to date. Don't worry, though; I'm here to give you a thorough overview of what we know - and don't know - including what dark matter is, alternative theories for it, and the various particles that scientists conceive could be composing this mysterious non-baryonic matter. Tune in to get caught up with the rest of us, who are all very, very confused (yet very, very intrigued) about this fantastical concept.

Did I name this episode after the "Choose Your Character" TikTok trend? Unfortunately, yes, but in today's episode, we'll be going over the 5 types of black holes, including primordial, stellar, intermediate, supermassive, and quasars. Tune in to learn more about scary sci-fi terms - such as "GALACTIC JETS" - and by the end, you should be well-equipped to finally choose your fighter.

I know, I know - black holes are super confusing. Don't worry, though, because I've got your back! In this episode, we'll go over everything you'll ever need to know about black holes, including what they are, how they form, and the various regions inside of one. If you've ever been stumped by the black hole's singularity, event horizon, Cauchy horizon, or ergosphere - tune in to have your doubts dismissed today.

(NOTE: at 2:55, I say that the gravitational field is determined by "mg" and is therefore constant, which was a thoughtless error on my part - the field is not constant around a blackhole! It varies depending on distance!)

This is it! The first episode of Nothin' but Space, where you get to learn more about Francesca - the formal host of Nothin' but Space, and your informal new space best friend :) Join her as she talks about how she became an astrophysics enthusiast - hint hint: it's never too late! - her favorite books, space topics, and more. And don't forget your cup of tea - you'll be here for a while ;)

(HAHA I had the biggest brain fart during this episode and kept referring to galaxies as universes . . . I meant there's a quasar at the center of every galaxy, not universe :p )
