In 2021, a PhD student named Alexia Lopez discovered something that shouldn't exist. Stretching across the distant universe is a massive smile-shaped string of galaxies known as the Giant Arc. It spans a staggering 3.3 billion light-years. To put that in perspective, the observable universe is about 93 billion light-years across; this structure takes up a massive chunk of the sky. The reason this is a big deal is because of something called the Cosmological Principle. This is the bedrock of mode
