Comment of the Week: I Don’t Know Much About Astronomy
This week I shared with all of you the galaxy map for Star Wars: The Old Republic, and I thought it was weird that some regions of space were in the same place that they would be in a map made 1000 years later. But MrFlibble set me straight.
The milky way galaxy takes about 200 million years to make one complete rotation, so a time period that seems like a long time to us, say 1,000 years, would actually allow for almost zero rotation in the cycle of a galaxy.
For example, a 1 degree rotation of our galaxy would take 555,555.55 years, so 1,000 years would only produce about 1/500th of a degree rotation in a galaxy.
Excellent work, MrFlibble. You da man.
