We are used to hearing about singularities in black holes... but what are naked singularities? What do they represent, and can they exist? Today, we will discuss this as well as singularities in general.

The real naked singularity is the friends we made along the way

wouldn't calling singularities infinitely dense be inaccurate? my understanding is that we are waiting for some kind of quantum gravity theory to explain where the limitation of infinitely approaching 0 volume is and that imaginary numbers like 0 or infinity can't exist practically

​@@Cosmos_elementary As a viewer and although I love this type of content I must say you don't look or sound enthusiastic about the topic you're presenting. Not saying you're not, but it comes across like that and makes people feel bored, like if you're not excited about what you're saying why should we. Really would love to see this channel grow so I hope this feedback helps!

​@@miseryrat1943 That's an interesting point. Maybe the issue here is a difference between Russian and English. In English you should speak more emotional to sound normal. He is a native Russian speaker so he speaks in English in the same way as he used to in Russian.

On the face of it, a naked singularity just looks to me like a black hole whose mass is insufficient to restrain light. Obviously this is not so, or our host wouldn't have made this video. Is there a simple explanation of why I am wrong, or am I so far off base that correction would require rewiring my brain?

Это как космос просто, только ещё проще, но почему-то на английском и с разъяснениями для тех, кто привык измерять всё в стадионах? И канал с 2020 года, но почему-то ютуб показал эту штуку только сейчас? Странные вещи происходят.... но вообще достойная попытка забранчиться на англоязычную аудиторию, особенно с учётом неясного будущего русскоязычного интернета.

"Singularity" is mathematical smoke and mirrors, a word that mathematicians use when they want to maintain their intellectual standing but are forced to give a word for an object or concept that falls betwween between size and no size, or between object and no object. Mathematics has no concept of absence; It cannot distinguish between presence and absence; so, for example, mathematicians can't realize that a radius of 0 is a contradiction, and quite a foolish one.Mathematicians hate philosophy, but they need it badly.

@@petrkinkal1509 How can anything with finite mass be infinitely dense though what dose that even mean? at what point that matter squeeze together you call it infinitely dense ? And if there's an end point that ain't infinite.

@@phuyaibankaengkro Density is calculated as mass per volume (mass divided by volume), so as the volume gets smaller the density gets larger and as volume approaches 0 the density approaches infinity. This is fairly simple math. Here are some examples. If you have 1 kg in 1 meter cubed the density is 1kg/m^3 If you squeeze it to 1 mm^3 (0. 000 000 001 m^3) you have density of 1 000 000 000 kg/m^3. If you squeeze the 1 kg to 10^-1000 m^3 you will have density of 10^1000 m^3. You can plot this in desmos if you want.

Zero is the most important number in mathematics and is both a real and an imaginary number with a horizon through it. Zero-dimensional space is the most important dimension in physics and is both a real and an imaginary dimension with an event horizon through it.

How could you possibly distinguish between an unimaginarily small volume and a point? And how could it make any meaningful difference to how a black hole works?

We have singularities in the two quark formations of two up, one down (female) and two down, one up (male). Those formations are 3 things that are not each other but are one (cannot be divided further). Leibniz called the zero-dimensional space binding our quarks together with the strong force the "Monad" which has two sides Monas (singularity) and Monos (alone).
