![]() Robotic aliens are also more likely to make such long journeys, as they will be far more durable than any kind of life we currently know. "Cultural evolution will eventually result in methods for improving intelligence beyond those biological limits," he added. Dick, an astronomer and ex-chief historian for NASA has argued. "Because of the limits of biology and flesh-and-blood brains," Steven J. Yet other experts also suggest that such robots could be the aliens themselves. This might be for a variety of reasons, but the time required for long journeys and investment in life support systems are chief among them. Similar to how we do not risk human lives on more extended space exploration missions, aliens may adopt a similar strategy. While this is obviously fantasy, it does raise some interesting questions.įor example, what would aliens look like? Many thinkers in this field believe that our first contact with aliens will be with robotic probes or drones rather than living creatures. To this end, they mount an invasion but are defeated through various interesting tactics and extreme sacrifice. To this end, they begin to prepare Earth for a new colony. In this series, the ant-like aliens called Formics do not consider human beings sentient since they lack a "hive mind". This, for example, is the premise of the First Formic War Trilogy in Ender's Game series of novels written by Orson Scott Card and Aaron Johnston. ![]() Whether intentionally or by accident, an alien species may wipe us out, or perhaps worse, consider us as a resource to be harvested. If so, they will be vastly more powerful, and may not see us as any more valuable than we see bacteria," he later qualified. ![]() "A civilization reading one of our messages could be billions of years ahead of us. "If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans," Hawkings said in a 2010 documentary for the Discovery Channel. He believes that bumping into extraterrestrial life would be devastating for our species and planet. Some of the greatest scientific minds, like Stephen Hawking, have famously warned about not announcing our existence to the universe. While we can only know for sure if an alien species would be aggressive by actually meeting them, we can make some educated guesses about how such an encounter may turn out. It is probably worth exploring if we actually have anything to fear before we get into the nitty-gritty about potential defensive strategies for our planet. Often depicted as either the most remarkable event in human history or its end, it would undoubtedly change everything we have ever thought about existence forever.īut, should things turn nasty, what could we really do to evade extinction? Let's take a look. ![]() First contact with aliens is a common theme in many science fiction stories. ![]()
