Ep 5. Life Elsewhere

Tomorrow's World was a British documentary series that covered groundbreaking scientific advances and technological breakthroughs. The show aired from 1965 to 2003, with a brief hiatus between 2004 and 2017. In October 2017, the series returned, with a brand new season.

Tomorrow's World season 1 episode 5 was titled 'Life Elsewhere.' The episode delved into the possibility of life beyond Earth. For centuries, humans have wondered if there is life on other planets or in distant galaxies. From science fiction tales to scientific research, the concept of extraterrestrial life has always fascinated us.

The episode explored the most up-to-date scientific research on the likelihood of life elsewhere in the universe. The host of the show interviewed a number of scientists in various fields who have done extensive research on this topic. One of the scientists interviewed was an astrophysicist who explained the requirements for the existence of life on different planets. He discussed how a planet's proximity to a sun, the presence of water, atmosphere, and the right chemical conditions are all necessary factors for the existence of life.

The show also looked at the search for extraterrestrial intelligence (SETI) project. This is a scientific effort to detect and analyze signals from extraterrestrial intelligence. The host of the show met with a SETI researcher to talk about how the project works. The researcher showed the equipment and explained how it was used to analyze signals received from outer space.

The show then focused on Mars - the planet that is most similar to Earth and, hence, the most suitable planet for life. The episode discussed how scientists have been exploring Mars for years, hoping to find signs of past and present life. The host of the show spoke with several scientists working on different Mars missions. One of the scientists talked about how they sent a spacecraft to Mars to orbit around the planet and gather data. Another scientist explained how they had landed a rover on Mars to explore the surface and conduct tests.

The episode also highlighted the questions surrounding Mars colonisation. With the possibility of life on Mars, scientists and billionaires like Elon Musk are considering terraforming the planet to make it inhabitable for humans. Musk believes that humans will eventually have to leave Earth to ensure the survival of the species and Mars is a suitable backup plan. The host discussed this with Musk, explaining how his plan would work, and what the challenges are.

The episode concluded by summarizing the findings of the scientific community: while we have not yet found concrete evidence of life beyond Earth, it is highly likely that it exists. The scientists discussed the possibilities of finding life on other planets, and the complexities involved in identifying it.

Tomorrow's World season 1 episode 5, 'Life Elsewhere,' was an intriguing exploration into the possibilities of life beyond Earth. The episode showcased the most current scientific research on the topic, and provided insight into the challenges that scientists face in this endeavour. The show also revealed exciting details about the search for extraterrestrial intelligence, and discussed the intricacies of colonising Mars. With its engaging presentation and thought-provoking subject matter, tomorrow's world truly lived up to its reputation as a groundbreaking science and technology program.
