Time dilation is the process of slowing down time. Yes, you read that right. It's like when you're waiting in line at the DMV, but instead of just standing there, you're actually slowing down the fabric of space-time around you.
Time loops are like a big ball of yarn, but instead of getting tangled up in it, you're actually getting tangled up in time itself. It's like when you're trying to get to the next level in your favorite video game, but the game just keeps resetting.
