This saying comes to mind as people seem to have an eagerness to venture into the unknown of our universe leaving themselves behind. Progress is what this type of explorations are called as only the ends results plus time can determine be it sane or insanity. The mind bearers explore into the Aether theories, which act as the medium for transmission of electromagnetic waves, and attempting to explore universal Black holes where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape it. This is very dangerous in the name of progress. There are two types of progress, good and bad determined by the outcome on human life and the life of our planet. Some things should not be disturbed as there are things which cannot be undone or put back to normal, such as the depleting of ozone layers and the refreezing of the poles just to name a couple. History has shown us the relics/remains of prior civilizations. Progress has not been proven to be a good lasting productive thing for humans. Is it necessary that humans rush into outer space, dive into black holes, or move faster than the speed of sound physically? Give some thought to the beneficiaries of human and planet destruction in the name of progress while manifesting sickness, destruction and death along the way. The future is about cloning of humans, robots/AI, space travel and survival among the less fortunate.
