"Setting aside the implausible notion that this superwave will travel 26,000 ly from the nucleus instantaneously,"
Since galactic superwaves have been described as "volleys of cosmic rays," and cosmic rays consist of massive particles that must travel slower than light, yyz was expressing amazement at the idea that the cosmic rays would arrive faster than the light-news from the event that produces them. Rather than casting dubious assertions, why don't you address the apparent contradiction?"Setting aside the implausible notion that this superwave will travel 26,000 ly from the nucleus instantaneously,"
Just as I suspected, Z can read, but he can't really think well. .
