✅ 1. There’s no such thing in science as “RGB rays.”
RGB refers to red, green, blue light channels — a digital/visual concept, not a type of radiation in physics or astronomy.
There are gamma rays, cosmic rays, and UV radiation, but RGB rays do not exist as a scientific phenomenon.
Sometimes this confusion comes from misheard terms like:
- GRB = Gamma-Ray Burst
- UV radiation
- cosmic rays
If you meant GRB, that does have a real scientific discussion behind it.
✅ 2. Gamma-Ray Bursts (GRBs) have not been confirmed to cause any mass extinction
Scientists have speculated that a very close gamma-ray burst could potentially:
- strip ozone
- increase surface UV radiation
- stress ecosystems
But this is theoretical only.
No extinction event in the fossil record has evidence pointing to a gamma-ray burst.
Some researchers have suggested the Ordovician extinction might be compatible with a GRB, but:
- there’s no physical trace
- no gamma-ray signature survives over geologic timescales
- the idea is speculative and not widely accepted
So: No confirmed GRB-caused extinction.
✅ 3. What does cause mass extinctions?
The well-supported causes include:
- asteroid impacts (e.g., Chicxulub killing the dinosaurs)
- massive volcanic events (Siberian & Deccan Traps)
- rapid climate change
- ocean anoxia
- methane release
- glaciation events
These are backed by rock layers, geochemical markers, fossils, and global sediment evidence.
No radiation event has ever shown this kind of smoking-gun signature.
✅ Bottom Line
There is zero evidence that any mass extinction was caused by “RGB rays” or even by gamma-ray bursts.
It’s an interesting idea that shows up in speculative science and online discussions, but not in the actual geological record.
