I don't know if you would call it a another world.   


A new analysis of three lunar rocks brought back by Apollo astronauts in the '60s breathes new life into an old theory some thought too simple: that the moon was created when another planet, Theia, crashed into Earth billions of years ago, leaving behind molten debris that eventually cooled and moved into a stable orbit around our planet.

The problem is that, after numerous inspections of the rocks, no one could find any trace of another planet. Until now. Previous analysis of the samples found they were identical to samples from Earth, when they should have shown some difference to indicate they also came from Theia.

But now, "we have ... discovered small differences between the Earth and the moon," the lead researcher tells the BBC. "This confirms the giant impact hypothesis." The difference detected is tiny indeed—the lunar samples carry a barely detectable abundance of oxygen-17, a form of oxygen that has nine neutrons in its atoms instead of the typical eight.

I sure am glad that astronomers from "billions of years ago" thought fit to supply the name of the alleged planet we allegedly collided with. And aren't we just INCREDIBLY lucky that the record of that name survived so many years later? I mean, the VA loses records in a matter of HOURS.

I could be wrong, but I think it came from the North.
