What’s really behind baseball’s home run surge?

Recent changes to the ball seem to be juicing hitters' stats. But could other factors, like the climate and advanced analytics, also be playing a role?
Earth is really ancient, and humans have only been around for a tiny part of that time. NASA

Curious Kids: how was the Earth made?

All the buildings and the cars and the restaurants, and the phones and even everything that's inside of you... it all started with an exploding star, billions of years ago.
