What if you fell into a black hole?

Let’s say you happened to fall into the nearest black hole? What would you experience and see? And what would the rest of the Universe see as this was happening?

Let’s say you decided to ignore some of my previous advice. You’ve just purchased yourself a space dragon from the Market on the Centauri Ringworld, strapped on your favorite chainmail codpiece and sonic sword and now you’re going ride head first into the nearest black hole.

“Life without science is meaningless” Mr.Do

Here is the list of frequently asked questions about space science. Some of them have been answered based on many persuasively scientific evidences, which are divided into two groups. They are theoretical arguments and observational evidences. Leave a number of a random question in the comment box below, the best solution will be sent back to you as soon as possibly. You can also ask for the mathematical models related to some particular questions (if further investigation is possible on trinhmanhdo.com)

  1. How old and how old is the universe?
  2. How did the Big Bang happen?
  3. What is dark matter?
  4. How did Galaxies form?
  5. How common are black holes?
  6. How many planets are in the Solar System?
  7. Are we alone?
  8. What is the Fate of the Universe?
  9. What will happen to life on the Earth?
  10. What is dark energy?

“A Grand Design for Dark Matter” – Trinh Manh Do

Good morning! Today we are going to investigate Dark Energy or generally visible matter, radiation. Even many theoretical models describing dark matter have been persuasively demonstrated, dark matter has not been detected directly, making it become one of the greatest mysteries in our cosmos.

Dark matter is invisible. Based on the effect of gravitational lensing, a ring of dark matter has been inferred in this image of a galaxy cluster CL0024+17 and has been represented in blue color.
