Human timelines are a blink of an eye. Until scientists figure out how to keep us alive and youthful forever, we will all perish when our time comes. It is inevitable.
Here’s an even more depressing thought
Think of all the advancements the human race will make after you’re gone. If you’re reading this, then you’re not going to be around to witness the colonization of space. Don’t you want to know what iPhone #20 looks like? What about flying cars and human controlled evolution?
Personally, I want all that and more. I want to know how everything ends. If it doesn’t end, then I want to know how it endures. I hate living with the knowledge that I will not be around to see humanity conquer the wonders of the cosmos. It’s like reading a beautiful work of fiction and having the author die before his vision could perdure through the simple act of putting pen to paper.
Alas, I have to accept my finite existence. However, here is a video that demonstrates on an appropriately cosmic scale what will happen in the far future. Granted it appears a little depressing, but not if you choose to direct your imagination towards the wondrous possibilities that will arise for humans and our place in the cosmos from our actions across the timeline.
