How the Universe Works

The programme offers a detailed look at the cutting‑edge technology scientists employ to deflect asteroids that could strike the planet. It examines how these methods challenge the once‑held belief that such impacts were an unavoidable catastrophe.

The programme titled is an episode‑length documentary that looks at humanity’s response to the threat of space rocks. It is presented as a single instalment within a larger series, and its focus is squarely on the scientific side of the issue rather than on dramatised storytelling. In the core of the episode, viewers are given a clear picture of the technology that scientists are developing to stop asteroids from striking the planet. The segment walks through the practical tools and methods that are being tested and refined, showing how modern engineering is being applied to deflect or destroy objects that could otherwise cause catastrophic damage. The film also points out how this technological push marks a shift from earlier attitudes, when an impact was often regarded as an unavoidable calamity. By detailing the current capabilities, the programme highlights the move from fatalism to active prevention, underscoring that the threat is now being met with concrete, scientific solutions. Overall, the episode offers a concise yet thorough look at the ways researchers are turning what was once thought to be an inevitable disaster into a challenge that can be managed. It demonstrates that, through focused innovation, the prospect of an asteroid impact is no longer beyond human control.
