Black Holes By Andrew Norton

  1. When you gave the sizes of the black holes does that include the event horizon?

    1. Yes, the event horizon is part of what makes up a black hole. It's the point of no return as they say.

  3. Do mini black holes stretch objects they collide with more or less than larger black holes?

    1. Miniature black holes are only hypothetical right now, so there is no real answer for your question at the moment other than a hypothesis. Mini black holes have a lower mass than larger black holes and have a short life span due to hawking radiation, so you would most likely see a smaller stretch of an object. But there is no proof to this at the moment, since we cant obverse them. Sorry there is no real answer atm :/

    1. When you say miniature black holes are the size of an atom, how do you know they even exist?

    2. Right now Miniature black holes or Micro black holes are just hypothetical. But Quantum Mechanics and Hawking radiation both conclude that they most likely exists. astrophysicists also think that we will be able to observe them in the near future.

  5. What technologies do astronomers and astro physicist use in order to calculate information on black holes?

    1. NASA is using satellites and telescopes that are traveling in space to learn about black holes. these can help us measure the visible light, X-rays and radio waves emitted by material in the immediate environment of a black hole. which helps us find out more about the mass, size, etc.

  6. If there is no proof of miniature/small black holes, then how did astronomers come to the conclusion that they are formed when the universe began?

    1. The conclusion of miniature black holes being form when the universe began is more of a theory then from evidence. the theory is that miniature black holes might have formed during the big bang. Some points expanded more rapidly than other parts, compressing some matter and squeezing it into miniature black holes.

  7. How do they determine the size of the black holes to know if they are miniature or large, etc. ?

    1. The mass of a black hole can be found by measuring the speed of the orbiting material, we also find out more about black holes by measuring the visible light, X-rays and radio waves emitted by material in the immediate environment of a black hole.

  8. Can a black hole shorten the life span of a star or affect the star in any way?

  9. When was the first black hole discovered?

  10. Do black holes vary in size or are they all about the same size?

  11. Why are miniature or small black holes no longer formed?

  12. Before something reaches the event horizon can it still escape?
