What Caused the Wow! Signal If Not a Comet?

TL;DR

The Wow! Signal likely wasn't caused by comets due to its extreme strength, narrow bandwidth, and lack of repetition. While some suggested comets could emit hydrogen radio waves, the energy level required would have been noticed long before. Ultimately, the origins of the Wow! Signal remain unexplained, and it may represent a potential first contact message from an alien civilization.

Key Insights

• 😑 The initial press attention created a misconception that the WoW Signal was explained as natural radio emissions from a comet.
• 🫥 The WoW Signal's frequency near the hydrogen line suggests it could be a natural frequency to use for contacting other scientifically minded species in the universe.
• 🖤 The WoW Signal's strength, narrow bandwidth, and lack of repetition make a comet explanation unlikely.
• ❓ Interference from Earth or equipment glitches are not probable explanations for the WoW Signal.
• 😁 The WoW Signal did not contain any information content but was a powerful unmodulated beam of raw radio energy.
• 👽 The characteristics of the WoW Signal suggest it could be a first contact message from an alien civilization.
• 🪡 Further investigation is needed to understand the origin and meaning of the WoW Signal.

Questions & Answers

Q: What is the most common misconception regarding the WoW Signal?

The misconception is that the WoW Signal has been explained as natural radio emissions from a comet, but subsequent developments have put this explanation in doubt.

Q: Why did the comet hypothesis fall flat as an explanation for the WoW Signal?

The WoW Signal was a very loud and narrowband signal, which is unlikely to be produced by comets. Additionally, the signal did not repeat, which is inconsistent with a comet's diffused and continuous transmission.

Q: Could interference from Earth or equipment glitches explain the WoW Signal?

Interference from Earth is not probable, as international agreements prevent broadcasting on the hydrogen line. Equipment glitches are also unlikely as there were no further instances of such glitches, and the signal had a smooth bell curve nature.

Q: Was there any information content in the WoW Signal?

No, the WoW Signal was an unmodulated beam of raw radio energy broadcast in a narrowband at the hydrogen line. The signal had no information content, but its strength and characteristics suggest it could be a first contact message.

Summary & Key Takeaways

• The initial story of the WoW Signal receiving press attention created a misconception that it was explained as natural radio emissions from a comet. However, subsequent developments put this explanation in doubt.

• A paper suggested that two comets emitting hydrogen could be responsible for the signal's frequency, but the signal's strength and narrow bandwidth made the comet hypothesis unlikely.

• The WoW Signal did not repeat, which is inconsistent with a comet explanation. Interference from Earth or equipment glitches were also unlikely explanations.
