I have lost track of current star estimates. I think the Milky Way galaxy was updated recently to 400 billion. Then I read galaxy estimates were up to 2 trillion recently. That is a lot of stars! All those stars...burning their precious fuel away (via fusion)...advancing closer to the day they will deplete their fuel entirely. For what purpose? To cast their energy and light (photons) into the vast emptiness of space? Rarely contacting anything. Nothing benefiting from that wasted star energy? Indeed, when I examine our own local solar system (to scale, on paper), I am convinced that 99.999% (or more) of our sun's light does not contact Earth or any other celestial body in our neighborhood! Just wasted energy over billions of years! I ponder things many days...today included. Is the underlying "theme" or purpose of our universe to simply waste matter/energy? If we conclude yes...should mankind comply with this theme? Use whatever resources we can...as fast as we can! Then move on to the next resource and use it up also. When gone? Expand out to other planets and tap them resources good too! After that? Get out to the other solar systems asap and start using those resources? With little regard to preservation or conservation? I understand this is a bold topic I present. Especially in a world which has daily headlines of "conserve this" and "conserve that". Still, looking at the cosmos... that type of practice(conserving) is opposite, or non compliant to what we observe and understand! In closing. I believe waste is 99.99999999% of what the universe does. Every second, of every day. Senseless and absolute waste of resources. Who is mankind to question this theme or be arrogant and not follow it?
