You’re the grillmaster at the annual family Fourth of July barbecue, and you’re sweating bullets standing over the grill in the sweltering summer heat. You’re trying to stay cool by pressing a cold beer can to your forehead, but to no avail. You can’t go inside because, once again, you’re the grillmaster and need to watch the food simmering on your freshly cleaned grill. Your brother-in-law is a university astronomy professor and walks over, asking how you’re doing. You say, “This heat is killing me. I feel hotter than the barbecue!” Your science teacher brother-in-law slyly says, “Try being an exoplanet.” You roll your eyes.
