When time reaches its limits, scientists call those moments "singularities." These can mark the start or end of time itself. The most famous singularity is the big bang, which happened around 13.7 billion years ago, kicking off the universe and time as we know it. If the universe ever stops expanding and starts collapsing, it could lead to a reverse of the big bang called the big crunch, where time would stop.
As our distant descendants approach the end of time, they will face increasing challenges in a hostile universe, and their efforts will only accelerate the inevitable. We are not passive victims of time's demise; we contribute to it. Through our existence, we convert energy into waste heat, contributing to the universe's degeneration. Time must cease for us to continue living.
