The things that Vera C. Rubin observatory sees

The Vera C. Rubin observatory sees everything, if something passes through the sky, the telescope will notice, record and notify it, including satellites that are seen as colored lines moving for the 2 seconds that the exposure lasts with each color filter, that is why they are shown as three-color lines, also things that were secretly placed there, I am talking about intelligence satellites, spies, military or whatever it is that those countries with a lot of paranoia and a military budget put into orbit for purposes that only they know about.

The United States government did not like the fact that this telescope could see its secret satellites, so it decided to involve the Department of Energy to develop the telescope's camera and designed its image processing in a way that erases the objects that the United States is interested in so that its enemies do not find out that they exist even before the file reaches the hands of the scientists who operate the telescope.

This also has the strategic advantage of alerting the United States government to the presence of enemy satellites the moment they appear in the sky, that is, the only thing that the Vera C. Rubin observatory is not going to show us will be what the United States government does not want us to see.

But I still have to tell you about the coolest thing that this telescope is capable of doing, when you can see all corners of the universe at once, you can also see through time, the most ambitious project of the Vera C. Rubin observatory will be the investigation of space-time as a legacy for posterity. Using 10 years of observations from every corner of the sky, he will create a film to observe the slow movement of the universe in fast motion, this will help us solve one of the biggest mysteries, dark matter.

But first I have to tell you first who Vera C. Rubin was a pioneering astronomer in a field dominated by men. Since she was a child she liked astronomy and even built herself a cardboard telescope. She was rejected by Princeton University for being a woman when she wanted to study astronomy and carried out research in observatories that at that time did not have bathrooms for women. Obviously she had a difficult time.

She was especially interested in studying nearby galaxies and when calculating their spin speeds she realized something enormous, observing that the stars in the outermost parts of the galaxies orbit the nucleus with the same speed as the stars close to the center of the galaxy, this does not make any sense according to the laws of Kepler and Newton.

In our solar system, Mercury is the closest planet to the Sun and is the one that travels at the highest speed, while the outer planets, which are very far away, take decades to go around the sun; in theory it would be the same, it would have to happen with the stars of a galaxy. In the Image the galaxy on the left is how it should rotate with the laws of gravity that we know and the one on the right is how they actually do it, the difference is enormous and can only be explained if there were a lot of invisible matter in the external parts of the galaxies, but that is something that is not there or at least we cannot detect it.

His research proved that there is a huge gap in our understanding of the universe and how it works. Our knowledge of gravity tells us that the universe behaves as if there were enormous amounts of matter and energy that we cannot see or detect other than due to its gravitational influence on the matter that we can see. According to this logic, if the total energy and matter in the universe were a cake, the real matter that we can detect and touch like us, our planet and the stars would only add up to 5% of everything, 27% would be dark matter and the rest energy. dark

Dark matter and energy are not necessarily invisible matter and energy or some strange phenomenon that we still do not understand in the universe, it can also be a simple error in our calculations, some concept that we have super wrong about something very fundamental, whatever, our numbers do not add up and we call that discrepancy dark matter and energy. There are many hypotheses to explain dark matter and energy and the Vera C. Rubin observatory will be our best tool to rule out the less brilliant hypotheses.

But like every time we have a new toy to observe the universe, the best thing is going to be the unexpected discoveries, the new questions that will leave us scratching our heads like the monkeys that we are, this always happens with every new large telescope and is when the biggest steps towards knowledge of our universe occur.
