Big Bang Theory

Real World Example

Imagine you're in a crowded party where there's barely any space to move, and suddenly someone drops a tray of drinks, causing everyone to scatter in all directions. This initial explosion of movement from a single point mirrors how the universe began with the Big Bang, where everything expanded rapidly from a singular, dense state. Just like the partygoers spreading out from the center, the universe's galaxies, stars, and planets have been moving away from the original explosion point, filling up the vast cosmic space over 13.8 billion years.
