High-Energy Cosmic Rays from Beyond This Galaxy

09/22/2017 9:03 AM

"Not to scare you, but you’re getting hit with radiation constantly. First, there’s just regular old light (yep, that’s a kind of radiation). Then there are low levels of higher energy radiation like the kind in nuclear reactors, including particles coming out of the soil and off of bananas. But the highest-energy radiation is the weirdest stuff. It’s literally out of this galaxy..."

Oh great, this supports my assumption before that, we could be alone in the universe. That all stars have been farted out by the galaxies.

It's the exhaust from a craft traveling at Ludicrous Speed.

Ludicrous, besides that might be offensive to Luddites.

Maybe it is that these particles are coming from the 4th dimension, but we see the effect as spatial anisotropy?

anything ring a bell here?

I don't get it. Are you trying to imply similarities between antithetical concepts in an attempt to bewilder? (BWBS)

The famous COBE cosmic background radiation plot you paste shows the very tiny anisotropies in the cosmic background radiation. Cosmic rays are many orders of magnitude above anything considered to be microwave radiation.

No, even though usually all I have is BWBS, because I sure can't blind anyone with my brilliance.

Thinking sort of (if you call that thinking), aloud.

Sorry for the extra "noise".

Yes, I get that cosmic rays can be so energetic that the energy (if 100% transferred on impact) would be very similar to being shot, well at least noticeable. Most likely they punch right on through with not as much interaction, right, and any damage and there is damage is very localized.

Here I show a link to a scholarly paper that I had zero part in producing, so attempting to distract from my other BWBS comments.

review paper in a book on cosmic rays

The most energetic cosmic ray detected so far was the appropriately named Oh-My-God particle detected in 1991. It is believed to have been a Hydrogen nuclei (proton) with a kinetic energy of 3*10^20 electron volts. To put this in more common terms this is the same kinetic energy of a baseball moving at 90 KPH.

It turns out these cosmic rays have an origin limit, else they interact with background cosmic microwaves and lose energy...

In reality, there are limits to just how far away an ultra-high-energy particle can originate from – since, if they don’t collide with anything else, they will eventually come up against the Greisen–Zatsepin–Kuzmin (GZK) limit. This represents the likelihood of a fast moving particle eventually colliding with a cosmic microwave background photon, losing momentum energy and velocity in the process. It works out that extragalactic cosmic rays retaining energies of over 1019 eV cannot have originated from a source further than 163 million light years from Earth – a distance known as the GZK horizon.

I thank you for providing my very interesting reading material, redfred.

Yeah, that sucker was moving so fast that, due to relativity, its mass was 320 billion times the mass of a proton at rest!

It was moving that fast and until it found our atmosphere, it was coasting.

I take my father's advice who says not to worry about things you have no control over or the outcome.

Probably just stray communication signals from aliens...
