What If We Knew the Time We Go Extinct?

What If | November 22, 2025



Within the vastness of the Universe, humanity is not that big of a deal. We’re not here because we’re meant to be here, we’re just… here. If mathematical predictions are correct, we might only have 760 years left. What would be the cause of our extinction? What would we do if we knew exactly when our existence will come to an end? Could we delay the inevitable?

    The sad true is that 9:16 we Humans and other living beeings are only a virus to the scale of the Universum. Lets say the flu we have in a Human Body last for two weeks. If u can calculate this two weeks in a universal scale than u have the exact extinction time of humanity for sure. Hier they say 50/50 just to keep things with hope. The truth is humanity will not last that long in reality as u seevin this simulation. On till than live happy and love ur child and family ❤❤❤❤

    If we cannot get our act together before destroying everything around then i hope it comes a lot sooner than that. I don’t want to die and i don’t want that for others, but we are not more important than all of the other life that has evolved on this planet and sustained itself by only consuming what it needs and not leaving a foot print. We as humans are only important to ourselves. Outside of our own minds, we serve no purpose on this planet and we contribute nothing, unlike the other species that we are selfishly wiping out because we all can’t even agree to use cleaner energy. Ultimately, our undoing will come from the greed of the wealthiest among us including corporations and their interests. They purposely put out false information in order to convince people that it’s ok to keep polluting, consuming, and procreating and that scientists predictions are all wrong. They only do this so that they can continue making money in the most destructive ways possible. I really do hope that we can turn things around, but like i said, if we can’t then it’s time for us to go and hopefully the next species to evolve with our intelligence will be better stewards of the Earth.
