I found this article from the MIT news, wonder If they could use this new material. Here's the link of the article: https://news.mit.edu/2022/polymer-lightweight-material-2d-0202 This is a paragraph with more information on the topic: The researchers found that the new material’s elastic modulus — a measure of how much force it takes to deform a material — is between four and six times greater than that of bulletproof glass. They also found that its yield strength, or how much force it takes to break the material, is twice that of steel, even though the material has only about one-sixth the density of steel.

Thank you so much for answering. Thank you very much for your reply and the links, I'll read them.

Thank you for your reply. I am actually not sure which are good sources, so happy to seek guidance. Thank you.

What are some massive black holes?

Thanks very much for your kind words Bufofrog, I got my information from this video. Do you think this chanel has good resources and information? Thanks again, bye!

I'm so sorry!!! Black Hole Stars existed 0.1 to 0.5 billion years after the Big Bang. But they don't exist now. Thanks for your input. I'm 8 years old and happy to be on this forum to learn.

I agree!!! But we can work on it.

Hi, I'm a new member, In this topic, we are going to talk about Black Hole Stars. Black Hole Stars were formed by Dark Matter Halo, which creates very massive stars that are million times the mass of the sun. They were so big that even after their birth, more and more gas piled on the newborn star. After a while, the core gets hotter and hotter but the external force crushes the core, making the core a Black Hole! A massive explosion happens but the star is so big that it resists even a supernova! The Black Hole is a few tens of kilometers inside a star, which is the size of the solar system.
