That all things eventually die. I have an ongoing existential crisis ever since I found out that I would die one day. Earth would one day be inhabitable, the Solar System would eventually become a cold dark place lacking the sun’s energy, humanity would one day be extinct, the universe would one day end. There would be no record of our existence.

But what’s worse is that we may never settle on another planet. We’re already running out of time. Climate change is going to kill us all.
