One should not be too distracted by definitions. Ideas transcend definitions.

If aliens did visit us, I'd be embarrassed to tell them we still dig fossil fuels from the ground as a source of energy.

Here's what I'm wondering: if, digitally, you can remove red-eye, smooth over wrinkles, make people look thinner, then why don't we have the technology to make me sing better?

No one is saying you're possessed by the devil anymore except the most ignorant of people in modern culture.

If Earth ever suffers a runaway greenhouse effect (like what has happened on Venus), then our atmosphere would trap excess amounts of solar energy, the air temperature would rise, and the oceans would swiftly evaporate into the atmosphere as they sustained a rolling boil. This would be bad.

While the Copernican principle comes with no guarantees that it will forever guide us to cosmic truths, it's worked quite well so far: not only is Earth not in the center of the solar system, but the solar system is not in the center of the Milky Way galaxy, the Milky Way galaxy is not in the center of the universe, and it may come to pass that our universe is just one of many that comprise a multiverse. And in case you're one of those people who thinks that the edge may be a special place, we are not at the edge of anything either.

Curiously, light-loving green plants reject the Sun's green light, reflecting it back at you, which is why they look green.
