Here's Explanation Group 3: Intelligent Life exists but Special & General Relativity are true.
- Faster than Light travel is a physical, hence, absolute impossibility.
- As the physical laws are constant throughout the Universe, only carbon-based lifeforms are possible.
- All life requires water & oxygen, no matter its forms.
- Per the Conservation of Energy, interstellar space travel is an absolute impossibility. The distances between stars are too vast to send life into space with sufficient amounts of air, water and food to survive the tens of thousands of years journey between the stars.
- Robotic probes are infeasible, as they cannot be controlled beyond one's solar system.
- Stars are moving far too fast for there to be anything but a short radio beacon from one civilization to another. For instance, the Sun goes around the center of the Galaxy at nearly 600,000 miles per hour, some 781 times the speed of sound, well over 200 times faster than the fastest rifle bullet. It is simply impossible for one civilization to reliably point a radio transmitter at another civilization.
- Physics beyond the standard model does not exist, which means that ideas such as a positive energy source from thermonuclear fusion are physical impossibilities; as such, every intelligent civilization will, ultimately, face its own energy crises.
- As with bridges and skyscrapers, rockets can only be made so big (eventually, they would collapse under their own weight), which means that lifeforms can only venture into space close to their home worlds.
- The sky is too vast for any civilization to monitor all the stars in its own sky for evidence of extraterrestrial communications; as such, most advanced civilizations simply do not bother to do so.
