Uncertainty

Watching a programme about gravity and quantum physics. The very big and the very small…

Hard to follow. There is apparently a fundamental problem in our understanding of the universe. General relativity explains Stars and galaxies. Quantum mechanics explains Atoms. But when you get to black holes the laws of nature fail.

Today Nasa published the very first image of a real black hole. Before today any images were just illustrations or mock ups.

The singularity at the centre of a black hole is apparently the same sort of thing as the singularity at the beginning of the universe.

The programme shows how something called quantum gravity explains the universe. Now we have seen a real black hole they may be able to take the theories further.

I’m leaving this now. I don’t understand!
