Can we officially rename Uranus to Caelus? Uranus (more accurately, Ouranos) is a Greek god. Besides Earth, all the other planets are named after Roman gods, thus Uranus should be named Caelus to be consistent.

That's not the only reason to rename Uranus

Can someone explain a concept to me? I never understood how gold rushes were profitable. If you suddenly found a mass quantity of a "rare" material, wouldn't it no longer be valuable since its value depended on its scarcity?

A "gold rush" probably didn't make gold abundant -- it was just enough to make a few people rich.

"The best diamonds are diamonds with slight natural flaws; that's what makes each one unique, like your love" -- my diamond dealer. Next up: CVD diamonds with controlled random flaws.

If that were true then IF graded natural diamonds wouldn't be multiple times more expensive than the VVS grades.

The words of salespeople should really ring hollow.

Depending on the resource, there may be latent demand that can be met when a cheaper source of a resource is discovered. Demand curves are not linear.

Often times, as a resource becomes more readily available, a ton of new uses spring up that were not economically feasible when the cost was higher.

IF graded natural diamonds are rarely more expensive than any colored VVS diamond (the coloration automatically grants a VVS since it's understood that the coloration in a diamond comes from inclusions.)

Two more weeks until GIA certification. The diamond course is the final one!

SpaceX' master plan revealed. Poor DeBeers.

My wife wanted a flaw in her diamond just for this reason.

I've always preferred "Terra" or "Gaia" to "Earth."

It could be a preference from video games, or maybe it’s because the common usage and being a synonym for ground and dirt has made the word seem ”low-brow” and the alternatives classy, exotic or poetic, and if their popularity was reversed we would think "Earth" was a classier word, but still.

“Terrans” will always sound better than “Earthlings” however. :)
