Later in the video when I fail to properly convey to Ambre which video I am talking about (to which she takes an educated guess about gravitational lensing), this is the footage I was referring to.

[juliant]

After she explained Fusion and Fission so simply... i fell in love lol.

[ShawnK]

I hope Ambre becomes a regular on the channel, or at the very least a frequent visitor. She's awesome.

Basically, our universe works around the fabric created from space and time. Gravity bends this fabric. But if something has infinite gravity, it infinitely bends the fabric, or in other words, it breaks it. This means there is no meaning to space or time, and the idea that the singularity is in a place is the same as the idea that it is in a time- it just doesn't make sense! Fortunately, black holes allow us the jomo (joy of missing out) effect of not knowing how this works. But here comes the point of experiment 5- if you are able to make a singularity push things away on the same level as it pulls them in, there is no event horizon, because light can escape at any point. But this mean the broken fabric is shown for all to see. The point Kurzgesagt made, is that we don't know what we'll see, since it goes against everything in physics, and yet it is physically able to exist. It is like how imaginary numbers work. We know there is no square root of a negative number, and yet we know it can exist because we can make predictions where the square root of -1 actually functions in mathematical equasions.

I would love to see more reactions to Kurzgesagt! There is so much cool, fun, and headache-inducing content worthy of being reacted to!
One of my personal favorites is "The Egg, " which is their narration (and visualization) of a short story by the same name.

[robotboytrbmobile]

Since space and time switch roles, you would be able to move throughout time (inside the event horizon) whilst you could only partially move in only one direction (towards the singularity).

[fabriziobiancucci]

4:20 Actually yes. It's call Black Hole Bomb and can release more energy than all the stars of a galaxy combined in several million years. Kurzsegart did a video about that, you should see that, it's very interesting

[denizkendirci]

7:19 you can image this one as looking a glass full of water from its side and strring the water with a spoon faster and faster. The faster the spin gets, the smaller the tube of distortion gets. Same applies to the black holes. The faster its spin gets, the smaller the even horizon gets. And in this video, he refers to a point that the spin is so extreme that the tube of distortion becomes just a line (so the event horizon completely dissolves because the warping of spacetime one dimensional (a line) that goes towards to dimensionless singularity (a point).

Also you can visualize the time and space gets reversed by thinking a sheet of elastic plane, one side red other side blue, which starts to warp by a singularity that causes the image we all have seen online as the one dimension reduced version of the geometry of a blackhole. Then, you try to imagine the region of spacetime warping inside the event horizon becomes so drastic, it turns the spacetime (elastic sheet, one side red and the other side blue) inside out, which is represented by the red side becomes blue and the blue side becomes red when past the event horizon so that an object falling into a blackhole travels though space and time but much more through than time as it gets closer and when it hits the event horizon, it becomes kinda stationary in space and now it travels much more through time rather than space. So it doesn't fall through space per se, it falls through time that point on. It falls to future.

I play this game called Elite: Dangerous where you basically just spend a bunch of time exploring the Milky Way. They did a really good job with a lot of the planets and stars, but what impressed me the most was the black holes. You can to travel to any of them in our galaxy, including the super-massive one in the center of the Milky Way, and view the lensing effect. It's absolutely mind blowing. Luckily for you as the player, they don't allow for you to get close enough to fall into one.

[kakuite]

14:52 She's basically saying you can see front and back of the blackhole at once cause the light don't follow general rule of straight path because of immense gravity, Jaby 😁

[blackman]

This is why they say that math is the language of the universe. What the universe wants to say to us can only be understood through maths.

[rafm]

I really enjoyed this segment with Amber.
I hope she comes back more frequently.

[ItsCoderDan]

Things like this that are technically possible, but never should happen because of very coincidental rules makes me think something or someone is responsible for this. I would really love to know what is this mysterious force responsible for it keeping such a chaotic paradoxical situations from happening

[TheSpiderworks]

So black holes are the literal Spaceball meme
"when will now be then"

[ranjith]

Man, she is brilliant that i can say. The way she explained about Fusion and Fission is great. I am attracted to her intelligence. If i got a girlfriend like her, we would daily talk and argue about all the science stuff .

[endresac]

yo they just released a video 'you're a dream of the universe', this will expand on the discussion you guys had after the reaction...

[ivanzamarripa]

wow thats so insane to me.. i genuinely had no idea that u could destroy the event horizon. that's so nuts! imagining the singularity still being there just without its vacuum

[thexlonewolf]

I recently saw Veritasium's video about how black holes work, and it went very in-depth on the whole "the singularity is in the future" statement. Einstein's field equations tell you how space-time is bent by a mass and the difference between two events near the mass, called the "spacetime interval." We visualize this bending using a sort of map that scientists call a "Penrose diagram, " which shows us everything we can influence or could influence us: it's a sort of diamond shape with the infinite future on top, the infinite past on the bottom, and infinite distance off to the sides. By convention, the diagram is scaled such that light always travels at 45-degree angles from the horizontal. If you draw two light rays out from a point in the diagram towards the top, the space between those rays represents everything you could hope to influence, as in order to influence something outside that cone, you would need to travel faster than light, which is just not possible. Similarly, if you draw light rays toward the past, the light cone that you reveal represents everything that could influence you.

When we add a black hole to the diagram, we represent it as an inverted triangle extending from the top left. The black hole's singularity is at the top of this inverted triangle, it's a final moment in time for anything that crosses the event horizon. That's the reason the singularity is in the future, when something crosses the event horizon, the only future it has is to meet the singularity. But something interesting happens when you look at the bottom of the inverted black hole triangle. At this point, your entire future is within the black hole, but there is no past in the universe that could affect you, so, what's in this past light cone? Well, when we draw that area, we end up with a white hole, a black hole's opposite, where if you are inside it, you have to be ejected off to the right into the universe. However, you could just as easily be ejected to the left, so what's over there? Well, it's another universe, parallel to our own. Keep in mind, this is what we have inferred just from the simplest possible solution to Einstein's field equation, and it already describes a black hole, a white hole, and two universes. It would be like someone laid out a coordinate system over just the northern hemisphere of earth, and someone else came along and said "this is fine, but mathematically, lattitudes can be negative, so there's an entire southern hemisphere we're missing. Oh, and more than that, there's a second Earth."

The real crazy part is that this discussion gets even more insane when we consider that black holes are spinning. Yes, for all their weird properties, black holes are even more screwed up than we give them credit for. If you take the solution to the field equations for a spinning black hole and take it as far as it will go, you end up revealing wormholes, infinite parallel universes, and anti-verses where gravity pushes instead of pulls. This is called "maximal extension" and it involves way too much mathematics for my migraine-prone brain. But needless to say, it is all very fascinating.

[Agent-]

Can we talk about the ost. Shit hits like a 18th century tragedy theme.

[fraymelgaming]

MATH AND SCIENCE AT THE SAME TIME?!?!?!?!?
THIS IS
