It's like my grandma said, 'the more you know, the less you really know!' It's mind-blowing that we're still trying to figure out the universe's age and size. I mean, think about it, we've only been around for like 13.8 billion years (yep, that's a BIG number!) and we already think we can map it all? Sounds like a cosmic game of "Whack-a-Mole" to me! What do you think is the most mind-blowing thing about cosmology? Share your thoughts in the comments below! #CosmicCuriosity #TheUniverseIsSoBig
