'I have no doubt that life is out there': Why radio astronomers are convinced alien contact is only a matter of time
Astrophysicist Emma Chapman argues in her book that the existence of extraterrestrial life is highly probable. She emphasizes that the vast number of planets in the universe makes it unlikely that humanity is alone. The search for alien intelligence continues to be a valuable pursuit for radio astronomers.
- ▪Emma Chapman believes that life exists elsewhere in the universe and that contact is a matter of time.
- ▪The Arecibo message, sent in 1974, was an early attempt to communicate with intelligent aliens.
- ▪The sheer number of exoplanets discovered supports the idea that Earth is not unique in hosting life.
