  Black holes are one of the marvels in the universe. There are so many of them and we barely know anything about them. In this article I’ll tell you about them.  If you don’t know what a black hole is black holes are  things that can suck up planets or even stars! There are different types. Supermassive, spinning or maybe just a normal one. Structure A black holes structure is quite unique. There are spinning black holes and non spinning black holes. There are also supermassive black holes. In normal black holes there is a disc around it called an accretion disc. Near that we have the event horizon. In the middle there is a single point with an infinitely small length but contains the entire mass of the black hole. For spinning black holes there’s a accretion disc and also an ergo sphere. An ergo sphere is the place where time is half broken but in the event horizon time is completely broken. For spinning black holes you can create a black hole bomb. But I’ll tell you ab...

Without the sun we wouldn’t be living and the solar system would be frozen. Today I will be telling you about it. Structure and temperature The suns temperature is pretty much the same as earths. There is the surface, the mantle and the core. The surface temperature is around 10,000 degrees Celsius and the core can reach the sweltering amount of over 20 MILLION! Length The mean radius of the sun is 696,000 kilometres and the diameter is 1,392,000 kilometres. Lifespan In about 5 billion years the sun will become a red giant. When this happens it will swallow Mercury, Venus and earth up whole! Eventually it will turn into a white dwarf and over a trillion years later the sun will end its live as a black dwarf.  Did you know? 1. The sun is actually white! 2. You can fit over 1 million earths inside it! 3. It’s radiation could damage earth!
