This comment leaves me in a void state. There's so much emptiness.The density of our population in a metropolitan city, is insignificant when you think of it at the scale of space.
I just picture me as one of trillions of rocks going around at an extreme velocity around the Saturn ring. Each rock represents a violent pass of this galaxy. We also know there's a black hole in the center of this galaxy, let alone we have many mores across the whole galaxy. What's even more void is this universe is so big, so big, so big we can't even know what's out there. What's with this tiny dot in this universe doing? So much life so much memory so much humanity, yet, we are so tiny. Indeed, we are so insignificant.
Turn our attention back on Earth. Every step we take every air we breathe, every rock we see, has a history. Our ancestors walked on our lands, all sorts of amusing creatures once lived on this planet. What's beneath us are the remaining and the history of planet Earth. Our petroleum oil is the product of the past living organisms. Years from now, our decedents will walk on this land like we do today, wondering about their ancestors' past, what they did, how they lived, amused at our modern fashion taste and our modern technology.
Are we the only intelligent organism out there? Is there another universe? As the universe expands, what does it mean? What's actually space and time without all the mathematics? Can we even picture what it is like for the universe to stretch, like a force field / shield expanding? Could we rewind to the past like in sci-fi movies? Can you imagine what it is like to have hundreds of billions of galaxies around us? Going to M31 would probably take at least 10M years at 60mph.
As I am writing this, new stars are borning, some other stars are about to explode, some stars and planetary objects are ripping apart by black holes, galaxies are ripping each other apart as they collide crossing each other's path, our space explorers out there are watching and analyzing the space out there, and other people whom I may not know are dying on this planet Earth. Mysterious forces are every where. Most importantly, our Sun is heading to a dying state like all of us, eventually the Sun will burn out and as it burns out, the temperature will rise to the point we can't survive on this planet. Eventually we will have total darkness and total coldness here, some billion years from now. Oh, and our planet is four billions old, and this modern human civilization is only roughly 5,000 years ago and "humans" probably around 3-5M years. Our legacy our human world may collapse due to human conflicts or due to cosmetic events, and then maybe we will turn into natural resources too. M31 is approaching and billion years from now we will be in another galaxy collision event. Perhaps the cycle will repeat.
We think everything in this natural world has one order: there's a beginning and there's an end state. But this perception isn't true at all. Our chemical compositions never lost, they just become other things, over time. Some of our human ancestors think when people die they become a star and at night they will shine and look after the livings. Those who died before us are already decomposing and becoming part of everything we experience every day. It isn't far stretch to say those stars out there, trillion miles away from us, perhaps did make up of other living creatures before us, and trillion years from now, our photon, might escape and able to travel to other stars.
This is depressing.
