Add CommentI wonder how the rest of the galaxy would appear from a planet orbiting one of these stars. As far as their own sun, it would look pretty much like our sun. However, with the velocity relative to other local stars dramatically different, most stars would be visibly red shifted or blue shifted and the closest stars would probably appear to move appreciably across the sky.

Oh, great. Killer asteroids aren't bad enough- now all we need is one of these bad boys doing a close pass to (or a run through) our Solar system.

Sorry Bill, but 2 million mph is only 0.3% of the speed of light. So any red/blue shift would be undetectable by the naked eye (for our eyes, at least).
Reply | Report Abuse | Link to thisWouldn't being slung away from the black hole also sling any existing planets off at various tangents, dependent on the position in orbit at the time of expulsion? Might there be a swarm of ultrafast lone wolf planets too?
Reply | Report Abuse | Link to thisSounds logical. Would we even be able to see these rogue planets unless one entered the solar system?
