There is clear observational evidence that hadrons and electrons are accelerated to extreme energies by astrophysical objects. direct evidence: charged cosmic rays. Part 2. Aliasing. Spurious Trend Removal. Introduction. Aliasing can cause up to 20 dB error in SRS plots. But a massive amount of ultra-high-frequency energy is required for this to happen.
