Early experiments bombarding two slits with one electron showed that it comes from both slits and makes interference with itself. Quantum physics affirms that electron 'dualism', as it can be going round the atom core only on certain orbits. And the actual position of the electron can be only described with a certain probability.
This probability issue was clearly pictured by Erwin Schrödinger with the cat phenomena.

The Earth has always been vulnerable to outer space.
Occurrences like large asteroids are rare, but natural activities, such as solar storms, strike from space much more frequently. These have a direct effect on electronic systems, especially satellite-based technologies.
The burst of human-made satellites has created a space hazard of its own, as the loads of orbiting debris have the potential to destroy other satellites.
In the US both NASA and the U.S. Space Force tracks space debris, the National Oceanic and Atmospheric Administration monitor space weather, Planetary Defense Coordination Office coordinates the search for potentially hazardous asteroids and other near-Earth objects (NEOs).
The European Space Agency (ESA) has pulled all these activities together under the umbrella of its Space Situational Awareness program.
The key should be in collecting all the data together and handling it with the help of Data Science methods.

To get to the both topics.
There are many parallels with the donations, taxes and private activities on the Earth and beyond - in the Space.
More complicated and obscure in the first case and hardly initiated and not cooperated in the second one.

I wonder if the tendency will develop into a clearer concept within several years. As it is crucial for technology return of investment and development.
And one for the benefit of humankind, as we may hear from every official claims.
