Alien Signals We’re Looking For Or Those We Think We’ve Detected

What types of things are we truly looking for when we discuss alien communication? Apparently, scientists are looking for a lot of things. The idea is that if aliens are trying to communicate with other sentient beings, they would do so through natural means in the universe. Any advanced society would be smart enough to do this, as it would make the most sense. This means that, by altering or using notable natural universal options, we’ll be able to pick up on that. For example, we’re watching for x-ray flares that might follow a specific pattern as well as optical/infrared signals that are modulated in an explainable way. On top of this, we’re keeping an eye on ultraviolet signals that follow specific sequences.

Ultimately, we’re looking for several based on radiation such as microwave or cosmic radiation that might show a specific frequency or degree of coherence. Extremely low-frequency, or ELF, electromagnetic waves that follow a specific pattern are also being followed. This is along with gravitational waves that do the same. Perhaps the biggest is following infrasound or acoustic signals, especially because space tends to lack very much sound as it is. Therefore, any sort of sound that can be heard is worth exploring. We’ve detected a lot of these over the years, some have yet to be explained while others have. Either way, the cosmic mysteries we’re uncovering constantly have been exciting for scientists. Because what if one day we do uncover true alien communication?
