Michio Kaku: The Universe in a Nutshell (Full Presentation) | Big Think

They ask: "If the

universe

exploded, what made it explode?" The answer is dark energy. Seventy-three percent of the

universe

is dark energy. Twenty-three percent is dark matter. If I picked it up with my hand, it would pass through my hand and fall. It keeps galaxies together. Twenty-three percent of the universe is stellar dark matter, composed of hydrogen and helium, and its percentage is four percent. of the universe. And us? We, the highest element, are composed of oxygen, carbon, nitrogen, tungsten and iron, which constitute 03%. In other words, we are an exception. The universe is made of dark energy.

The universe is made of dark matter, which constitutes. twenty-three percent? Nobody knows string theory. It gives us a clue, but there is no definitive answer. In other words, you, the ambitious young people listening to us, are now

ing: why would I want to be a physicist in the field of unknown hypotheses? , good? He realized that every physics is a textbook. This is incorrect. All physics books say that the universe is made of atoms. The point is that the universe is made of atoms. Over the past ten years, we have come to believe that most of the universe is dark, and that there is a shelf

of Nobel Prizes for young people who discover the secret of dark matter and energy.

Let me give you some advice. If you're a young physicist, you may have graduated from school with dreams of becoming Einstein. You have a dream of working on linear theories and something like that, and then you come across modern physics. They fail most students in elementary physics, and we also encourage a little engineering. We don't want to teach engineers to build bridges that might collapse. We don't want to find engineers who design skyscrapers so that they fall there: it has to be done. Learn the laws of motion before you start working with Einstein's laws. You have to work with the laws of friction and levers, pulleys, gears, and as a result, we are disappointing elementary physicists.

So if you're a physicist, you're a newcomer. high school, with eyes for physics, and you are learning about physics for the first time, be careful if they make it difficult for you. That's how I started as an experimental physicist. Then I moved to Harvard and. Then I spoke to my mentor, one of the greatest experimental physicists, Professor Bond at the time, and he said to me, "Maybe it's time for you to take a break." This is what he told me: "Your skills are a great fit." well with what I loved most, which was the hypothesis" of mathematics.

The world of higher dimensions, and then I realized that this is probably true. The thing about physics, or any science, is that what I'm really interested in finding the basic rules for everything, instead of flirting with a theory, or making your own theory prettier. Why don't I find out if it works? What motivates him? I am a theoretical physicist. Thank you very much. Scientific translation. Engineer Iyad Abu Hijleh, Amman-Jordan.
