From atoms to the Andromeda galaxy

 Facts about the human body: From atoms to the Andromeda galaxy

- Man is made up of approximately 7,000,000,000,000,000,000,000,000,000 (7 octillion) atoms, each billion years old. For comparison, our galaxy has about 300 billion stars

- Most of the atoms that make up our body consist of space. The nucleus at the center of the atom is so small that it is the size of a golf ball in a football stadium.

- The atoms that makeup matter are never intertwined. The closer they are to each other, the more their component charges are repelled. It is like trying to bring together the ends of two strong magnets with the same charge. For example, when you sit on a chair - you do not "touch" it. You stand a certain distance from the chair due to the repulsive force on the atoms.

- Everything we feel is made of molecules. The largest molecule in nature is the first chromosome in our body. The largest known molecule at the moment is DNA, the first human chromosome. It holds about 10,000,000,000 atoms.

- Each person was in a single cell state for about half an hour

- The size of your eyes will never change. From birth to death. Nose and ears never stop growing

- The strongest muscle in the human body is the tongue

- The jawbone is one of the strongest bones in the body

- A person uses 200 muscles to take one step

- All functions in the human body stop when the axe hits

- In a day, the human body produces enough heat to boil 30 litres of cold water

- Each of us spends more than 20 years of our life in sleep

- In terms of cell count, we have more bacterial life than ourselves. The human body consists of about 10 trillion cells, but bacterial cells have 10 times that number. Some bacteria are even beneficial.

- According to experts, the human eye can distinguish 10 million different colors

- If the human eye were a camera, it would have 576 megapixels. When reading a 300-page book, the eyes "travel" a distance of 1 km

- If you can see the Andromeda Galaxy (the closest galaxy to the Milky Way) in the evening sky, then you can see as far as possible with any technology. The distance to it is 2.5 million light years. The photons you see started their journey 2.5 million years ago. So you travel back in time)
