If extraterrestrials exist they are certainly not biological, flesh and blood aliens. That would be impossible. I base this on the fact that matter cannot travel faster then the speed of light. It is a fact, and anyone who disputes that fact can simply prove it wrong by showing the math and not depend on magical thinking. Even assuming there is an advanced technology that could somehow warp space for faster then light travel, the energy involved would consume an entire star to briefly create such a wormhole. It would not be economical. Even our space brothers bow to economics.
I assume extraterrestrials would behave much like we would, using simple logic. We sent many probes to Mars. A probe is far cheaper then a human mission. Let us assume in the future we want to explore planets outside our solar system. We’ll send probes. Assuming in the future if we have the technology to send a probe even half the speed of light, we could send hundreds of probes to explore our galaxy. We won’t be alive to see the results, but future generations would.
Matter cannot travel faster then light. A crew of biological aliens would take perhaps a thousand years to visit one planet. We wouldn’t do that, and so would not any extraterrestrial civilization no matter how advanced. Just like with our Mars missions, extraterrestrials would certainly send probes that could take hundreds or thousands of years to reach their destination. And then it would take hundreds or thousands of light years to send back a signal at the speed of light. The communication with such a probe would not be worth the effort…unless the probe used a quantum entanglement/teleportation “radio”.
If matter cannot travel faster then the speed of light, information might be able to. Instantaneous communication using a probe with quantum entanglement might just be possible. The trick is to send the quantum “communicator” first. Once it is in place, instantaneous communication could be possible even thousands of light years away. Why send our “space brothers” when a probe would do just as good? I imagine that is how we’d do it once we mastered this extreme (but not impossible) technology.
If extraterrestrials exist, then they are watching us. That is what we’d do. Their probes would be a combination of artificial intelligence and robotics. Robotics would have no need for food or air. They would self-repair. Artificial intelligence would be essentially immortal…they could travel for thousands of years on the way to their final destination. If the original, biological life form still existed…who could say.
If physical aliens are visiting us they are certainly humanoid robots. It is what we’d do in the distant future. We’d use androids to collect information and spend it back using quantum “messages” from the mother ship. A mother ship would have multiple probes (UFOs) and these probes might have extraterrestrials robots for closer contact.
What about alien abductions and the true accounts of contact with biological aliens? Well, that is something different then the physical nut-n-bolt alien probes. Or maybe extraterrestrials are connecting with us (if not physically)…if there is a true intelligence BEHIND the quantum tunnel.
