umm ... "SPITING" bullets? I have no idea what you think an "old saying" means but they usually make some degree of sense.🖖

Admittedly, cosmic rays are significantly more energetic than the neutrinos shooting through you right now ... 😁😎

And, interestingly, given the same information to begin experiments to test the idea, even if the experiments are *_WILDLY_* diverse, will tend to gravitate toward the same, reproducible, actual, _factual_ result. Stranger than fiction. 🖖

Quasars have been extensively studied and many examples can be found in space.

@TheUnholy_ if they know everything about them like they talk then why study them?

What's the difference between a duck? Your question is nonsensical.
