09 Cosmic starry sky
Several important planets in Orion will explode in the future, ending the pursuit of the Seven Sisters of the Pleiades.
Carinae - Seamount II - Big Bang hypernova - Cataclysm, releasing a lot of radiation
Stars are born from collapse and die from collapse, from dust and nebulae.
Nothing lasts forever, even the stars die.
11 Climate change
Venus - the atmosphere is all CO2 - no heat is particularly hot
Most of the Earth's forests are in the Northern Hemisphere
10 The Son of Electricity
" Nothing is too wonderful to be true if it be consistent with the laws of nature. " - Faraday
Faraday, who had not studied for a few years, taught himself to be a great scientist who solved Newton's [how planets revolve around the sun without approaching the sun] and inspired Einstein's theory. Discovered the relationship between electromagnetism and light.
He is also enthusiastic about public affairs and has held popular science lectures for young people for many years.
Maxwell perfected the theory with mathematical knowledge (he couldn't do it without going to school).
is a great man.
Earth is a big magnet - the magnetic field blocks out cosmic rays and protects life on Earth.
Migratory birds recognize the way - identify the direction through the magnetic compass in the body
11 Climate change
The moon landing program was a byproduct of the Cold War, not a dedicated astronomy program
12 Towards the future
The largest library in the Ptolemaic era - manuscripts of many classics such as the Bible in the era of the Big Bang of Knowledge spread to the world from here
Radiation - Supernovae - Dark Matter (which occupies most of the universe and makes the Big Bang faster and faster) - Voyager (a billion-year lifespan carries human information, music)
When I take all of this into my heart and my mind, I'm uplifted by it. And when I have that feeling, I want to know that it's real, that it's not just something happening inside my own head. Because it matters what's true, and our imagination is nothing. Compared with Nature's awesome reality.
13 Explore the future
Is it possible that life was brought to Earth from aliens through meteorites exploding after asteroid impacts? Or take it elsewhere from Earth? Many microorganisms have been found to survive in the extreme environments of the universe.
We have been emitting infinite radio waves like the universe for more than seventy years, and the first radio waves have swept across thousands of planets.
Closer stars won't go supernova (do us harm) in the next few million years
Every million years, there will be a huge volcanic eruption on the earth
Native Americans were brought down because of viruses such as smallpox brought by Europeans (?)
The sun will die in about five billion years
If advanced intelligence is the greatest trait of our species, then we should make it perfect like the rest of the planet to benefit us instead of abusing it
