Up: Long Delayed Echoes
Previous: Solar Cloud Hypothesis
- Proposed in 1971 by researchers from Stanford University.
- A probe sent from an extraterrestrial civilization might
be in orbit around us, looking for electromagnetic signals.
- Upon finding a signal, and having no way to (necessarily) decode
it, the probe might simply re-transmit the signal received.
- These same researchers admit that the likely eventual explanation
will be unspectacular.
