The world can not sustain life for ever. There is no God going to come and save us. If human race has to sustain, we have to look after ourselves.
Yes, there are risks, we might find a more advanced civilization that would come and conquer us, but its a risk we have to face. Humans have faced this forever. We started looking at world as our own neighbourhood, then we invented more advanced travelling machines, then we got to know about continents, and then globalization came into being. Every time, we had to face a lot of challenges, slavery, misunderstanding, yet, we have come out as winners.
Its high time we forget the petty issues, this inch of land belongs to me, it belong to you, blah blah, it 'belongs' to no-one, a simple meteor strike can wipe the entire humanity out in no time.
The interplay between economics, fundamental science, human thinking is fascinating. I wish/hope there is a way to incentivise humans to think of the future that is billions of years away, and stop thinking of the span of a single person's lifetime. I think it might be one of the reasons, our ancestors, brought in the concept of soul, as an indestructible one and that lives on and on, so that we stop searching for for happiness and satisfaction in the lifetime, and work towards a life that is billions of years long (yugams - https://en.wikipedia.org/wiki/Yuga
Screw you religion, lets live for the greater good of humanity. I still have a feeling that religion was never part of Indian culture, and is never is, and should never be. Wishing for a time when humans put all their collective energies to advance our understanding of the universe and whats beyond it. Lets keep the unknowns as unknowns (https://www.youtube.com/watch?v=-nQDNNYyjJ4
), its okay to theorize, but its not okay to say an unknown as known without evidence, and applying psychological pressure and societal pressure to force a thoughtful mind into the world of imaginative knowns without any proof.
Great laws are out there, which have been theorized, and are yet to be proved, and are looking for people to help prove/disprove, enhance/deconstruct, and we are spending our time trying to convert people from one belief system to another trying to incentivize them through psychological and economical means. We fail to understand that these numbers mean nothing, millions of square kilometers and the count of billions of people mean nothing, if the day comes, and earth is not a suitable planet to survive, none of these counts is going to help.
We all are still observing time as a linear concept like the individual observer from his plane own plane of reference. Its high time we teach spacetime and not space and time!
There was a time when seafaring was dangerous. Space is the next big frontier, time to make the next big leap!
PS: I know that all above is incoherent bits of blabbering, just frustration coming out. For those who took time to read it, thanks and would appreciate the thoughts, if any!
