Four discoveries that would change the world

In the future will beleive things that today seem kinds of crazy kind of like how it was once crazy to think the earth orbits the sun or that humans evolved from apes here are four big ideas that right now seem kind of far -fetched but in the future might be no big deal the universe contain all that is was or will be but  what if that's not actually every think like may be space  is so big that partsvof it are completely isolated from everything elseor may be every quantum interaction really does spilt really with each branch evolving a universe of its own we may well detect those other universe someday and then we'd know for sure not only we not the centre of everything neither is our universe what if you are not really you every decision you think you make is really just the result of crazy complicated but completely predictable chemical reaction in your brain it's an old question for some but as we learn more and more about how the brain works we find less and less room for free wall what with a world without free will be like i'll be enough probably not that different than how things are now but we would be the same the only scientists being on  earth but if that's not true we're already starting recognize that chimpanzes have at least some human right what if someday we discover or just decide that all kinds of animals are just as concious as we are and that we have not really been treating them all that well would that mean me really is murder and finally our brain have given us a huge advantage for the lost hundred thousand years or sonbut that's nothing compose to the billion of years that life has existed on earth in terms of evolution the only thing that matters is the ability to survive and reproduce and our intelligence has allowed us to do that pretty well so far but what if being smart is not so smart like we can invent our way out of just about any mass but we  are also great at inventing our way into new masses and some of those can be preety bad even catastropic what if the really long run it is better to be simple dumb and just really good atvreproducing of course we cannot proven any of this for now but the biggest ideas  always start with a simple question what if
