Is Earth's Atmospheric Thickness Related to Cosmic Ray Radiation?
Why does cosmic radiation diminish entirely, reaching zero, at sea level?
If the atmosphere's thickness were random, it should not happen at sea level, but at a random altitude.
Is there a specific ...

Is an alpha particle cosmic ray more easily deflected on its journey than a proton? Or vice versa?
Has everyone heard about the cosmic ray that hit Utah recently with an energy of about 240 EeV? Making it the third-highest-energy of all time? Scientists say it seems to have come from a void, and ...

How has cosmic ray flux changed over time?
Is the flux of cosmic rays now greater than it was in past eras of the Universe, less than it was in the past, or is it roughly the same? Is the answer different depending on what type of cosmic rays ...

How do the abundances of heavy elements near the Solar System compare with the abundances at other places and times in the Universe?
We have measured the relative abundances of heavy elements (e.g. gold, lead, uranium) near the solar system and in cosmic rays. I'm interested in whether those abundances are particularly high (or low)...

Why are most cosmic rays positively charged? Has anyone figured this out yet?
It is by now very common knowledge that the vast majority of (known) cosmic rays are protons, alpha particles and such, yet I cannot find in my recent reading any discussion of why this might be, or ...

Cosmic rays characteristics/parameters
Where can I get the numerical information about cosmic rays? This is what I need:
Cosmic rays composition: As I found here 99% bare nuclei and 1% electrons. out of 99% bare nuclei: 90% protons, 9% ...

In the observed cosmic rays resulting from a supernova, can we expect electrons to arrive before protons?
In the Introductory Astronomy book I'm studying (Astronomy 2e, OpenStax.org, Fraknoi et al.), cosmic rays are said to include protons and electrons, among other components. It also says that the best ...

Is there an equivalent of the red shift effect for cosmic rays?
I had read somewhere that light from very distant sources can be measured to be increasingly red shifted the further away the object is (due to cosmic inflation?).
Suppose you had an object emitting ...

Earth's magnetic field vs. refrigerator magnet
According to this article:
The Earth's field ranges between approximately 25,000 and 65,000 nT
(0.25–0.65 G). By comparison, a strong refrigerator magnet has a field
of about 10,000,000 ...
