He won't, realistically. If he can make more money spending the same amount of time making videos for a more popular channel that will see greater revenue. And hence, greater ability to continue producing quality videos. Not that his format is particularly expensive compared to content creators who are a bit more hands on with their content. Not just sitting behind a desk. All he really has to pay for is the staff, writer, editor, etc. He already has the equipment, so there's not AS much cost associated with this format.
XPLRD was doing similar numbers when Simon killed that one. As we’ve seen from Casual Criminalist, Simon will still run some channels that are not making money if he likes them enough. Simon is a huge space nerd so I’m not expecting it to go anywhere anytime soon.
Now that we’ve covered supernovae and hypernovae, now we need a script written on the ‘kilonova’: the explosion resulting from the kind of scale including two colliding neutron stars. From these kinds of novae, entire Earth masses-worth of elements like gold and platinum are produced
If we examine the crime scene in the infrared spectrum we can see a red shifted after image of the killer at the time of the slaying. *puts on blackhole sunglasses* I guess the killer wasnt that bright. YEAAAAAHHHHH!

One major correction. Stars massive enough to go super nova do not live for billions of years. Tens of millions max, with the most massive only living for a few million. There is one type of super nova that is an exception to this rule though. Type 1a super nova. They occur when a star around the size of our sun is in a binary system with another star of around the same size or bigger. The sun sized star will die as ours will, leaving behind a white dwarf. When the companion star gets old enough to star expanding, the white dwarfs gravity will start attracting the mass furthest away from it companion. Once it has attracted enough to reach a specific mass, 1.4 times the mass of our sun, it goes super nova. These are the only stars that go super nova that will have lived billions of years before it happens. All others, including all hyper novas, are from stars only millions of years old.
For those of you who didn't understand, literally every element above iron requiers a Nova event to form. Everything from Cobalt up can only be formed by such extreme energy.
I'm surprised you skipped over the pair instability supernova so quickly. They're _weird_ because they don't leave anything behind - they just explode completely.
Absolutely untrue. There is an event called an UnNova. When a star goes supernova but the blackhole is formed too quickly and absorbs the supernova before any material can be ejected. Rare, but if the conditions are just right, the star appears to just blink out of existence. Cheer Beard Boy
The black hole jet just discovered dwarfs even these. The jet is a staggering 23 MILLION light years long that's 140 times the size of the entire milky way. It is bigger than any known galaxy.
It always confused me as a kid that nebulae are both the remnants of a deceased star, and a large gas cloud where new stars are formed. It's crap that they have the same name for two different things. Before we knew what galaxies were, we used to call them nebulae as well.
I thought I understood standard candles, but this made me second guess my understanding. I thought supernovae were so consistent in their brightness regardless of distance and redshifting, how is it that they can vary in size?
Only certain types of supernovae are considered to be "standard candles". Those are known as type 1a supernovae. Other types can, and do, vary in brightness.
I still want to know what our current universe looks like today (since light is so old) and are the forces that created galaxies still making new galaxies? Also is Andromeda closer than we think because of the time that it takenfor light to travel?
There may be no stars risking the earth of a supernova but 1g of nickel moving at 99% speed of light is equal to a 151 Kiloton nuclear bomb hitting earth.
@@kayalee783 Watch the shadow moving across the Earth. The shadow is going West to East, meaning that night falls West to East, the opposite of reality. Stars/camera may be moving, but the shadow knows.
the big bang is weird. it happened at a single point but because it created the universe it also happened everywhere including where the universe hasnt expanded into yet. The more you understand it the more you dont understand it lol
they are different types of events. Kilonova is two neutron stars merging. The bang is smaller but more intense. The higher intensity is necessary to create the heavier elements
It's actually neutrinos, hypernovas sound completely ridiculous even compared to this ua-cam.com/video/Yt-SBT7nNfU/v-deo.html - Gamma-rays don't decay (they might red-shift though, which is a kind of decay), they are primal like the electron and light - as far as we know.
Gamma rays do not decay into electron-positron pairs. Gamma rays consist of ultra-high energy photons. Photons do not decay. Also, are you sure about the "nickel moving at 99% of the speed of light" bit? I would think more like 9% (which is still reeaaaaalllly fast).
Gamma rays do actually form electron position pairs above a certain energy. This pair production takes the energy the star needs to fight back against gravity, and triggers a pair production supernova. One particle changing into another particle or group of particles is called "decay". So no, gamma rays can and do decay into electron position pairs, and that process triggers certain types of supernovae.
What happens is that pairs of gamma rays produce electron-positron pairs which turn back into gamma rays. If this gets out of whack and you get too many electron-positron pairs at once, boom.
@@Real_Artician Doesn't that require that the gamma ray collide with another particle? Either way, A. this is a fascinating subject and B. I am neither knowledgeable nor stoned enough to hold up this argument.
@@Real_Artician ok so i dropped physics as a major when it got too math-y. I did some reading and yes, especially in the environment being described, exactly what you describe apparently can occur. Look, Simon - discussion!
@ruthere4pretender It is so nice to have not read trolling as a response. It's actually pretty easy to visualize with Feynman diagrams without getting too deep into the math. The electrons and positions do recombine, but the resulting gamma ray has much lower energy from entropy from two reactions being taken out. The difference means the resulting photons are essentially governed at a certain energy, which now can't support the star's mass. And no, to the other commenter, it's just one gamma ray, not a pair. The energy loss from a single photon creating an electron and positron, then collapsing back into one photon is where the energy goes. Photons are neutrally charged, they don't interact with each other at all so two photons can't react directly with each other in any way. If you shine two laser pointers perpendicularly through each other, there is zero collision or deflection.
This is a very interesting and satisfying channel. Thank you for this one Simon.
I am loving this channel. I know it's not doing as well as many of Simon's others but I hope he keeps it up.
I've recently unsubbed from all of them except this. The quality has fallen away, many errors in many videos nowadays.

Exactly. His next iteration should be a gaming history channel
It’s wonderful how you explain things so quickly, fluently and yet logically, understandably, entertainingly! 🎆
Thank his writers. 😅
you need to advertise this channel more. i only found it by chance
He's just starting out but he'll end up having several channels before we know it.
@@Thanos916 Simon already has a bunch of channels, and he's been doing youtube for many years now
I think this one is newer. All are better then whatever history/discovery channel have turned into
Hypernova is definitely more fun to say!💥😄
I completely love this channel and this video in particular. Doing a great job, Simon and Co.
I've never seen a hypernova blow up, but if it's anything like my old Chevy Nova it'll light up the night sky!
Thanks for letting me nerd out on the universe through astrographics Simon best channel although they are all great!
You should do a Situation Room for this channel. The weekly space updates scene is big and some channels like Marcus House do very well.

One of my favorite channels, Simon.

If you were between the sun and earth vs between the mood and earth the rotation would be different.

Some stars skip this hypernova step. They implode and leave nothing behind. Few examples are suspected of this happening.
