I love to learn. Although my head is primarily filled with useless, odd-ball facts, I'm still hungry for more. I like to learn something every day.
Today, I learned that our solar system will end in approximately 5 billion years when our sun runs out of fuel, becomes a Red Giant (before becoming a white dwarf) and sucks in the inner planets, including Earth.
Regardless of how significant or insignificant, share with us something that you've learned today.
