The universe has a lot of mysteries, but if you don’t learn it, you never know.
There is so much we don’t know about this vast, magical universe. It contains hidden secrets that if you don’t learn, you might not know all this life.
1. The solar system is raining too – but not like you might think
Rain, but it’s a meteor shower. It is the celestial debris of the solar system falling to Earth, with a weight of tons!
Most evaporate along a beautiful path, forming the shooting stars we often dream of. But they’re not that scary, because most of the time these comets and asteroids float in interplanetary space, between the orbits of Mars and Jupiter.
In addition, it is very common for a meteor to fall on Earth, but most of it was burnt by friction with the atmosphere.
2. The sun may interfere with your device.
Beautiful, powerful and unpredictable – it was the solar storm. This fact is proven by the greatest solar storm of 1859.
Rays of light are emitted by the Sun, they travel through space at the speed of millions of kilometers per hour. They interfere with telegraph systems and even cause large-scale electric flashes in the United States and Canada.
If solar storms of this magnitude hit Earth again, they could disrupt satellite orbits, scramble global telecommunications signals, and there is nothing humans can do to stop them!
3. A total solar eclipse will probably never happen again!
The Moon covering the Sun will create a partial or total eclipse. However, the eclipse is slowly disappearing, as the moon’s orbit increases by about 4 cm per year. In the next 600 million years, the Moon will be so far away from us that it will no longer be large enough to completely cover the Sun.
In other words, a total eclipse will never happen.
4. It only takes an hour to travel in space!
By calculating the speed of a spacecraft and its altitude above the ground, the Hungarian and American physicist Theodore von Kármán discovered a border between Earth’s atmosphere and outer space. The universe. He named it Karman Line.
The limit of the Karman Line is just 100 kilometers from sea level – the equivalent of 250 laps around an Olympic track! This means that with the speed of an ordinary rocket, it takes about an hour to be officially called a “space astronaut”.
5. Completely different from what we think, Neil Armstrong’s imprint will not be on the Moon forever
Unlike the Earth, the Moon is not subject to wind or water erosion due to the lack of air and water on its surface. Therefore, many people believe that Neil Armstrong’s imprint here will last forever.
However, the sun’s wind – a flow of charged particles – will change the wind that usually does. This means that this imprint will disappear over time.
But this phenomenon will not happen overnight. Armstrong’s footprint on the moon will last for at least 100 million years until the rocks are eroded.
