The claim is that several star clusters in our galaxy appear to be "alien", that is, to have somehow wandered into our galaxy from elsewhere in the cosmos.
No mention is made of the big bang idea. I may be missing something, but it seems to me that if the entire universe is expanding from an original big bang, then everything should be expanding outwards from an original center, and there should not be any possibility of star clusters and/or mini galaxies containing them somehow "wandering" into our galaxy; that would seem to require that they "wander" faster than the speed of the basic universal expansion."It turns out that many of the stars and globular star clusters we see when we look into the night sky are not natives, but aliens from other galaxies," said study co-author Duncan Forbes, an astronomer from Swinburne University of Technology in Australia. "They have made their way into our galaxy over the last few billion years."
What am I missing??
