In the concluding episode of the series, Jim encounters ever larger cosmic structures to reveal the latest breakthroughs in our understanding of the universe. For example, Jim comes face to face with our galactic home, the Milky Way, a monstrous structure sculpted by the gravitational forces of dark matter. Jim finds out from pioneering researcher Adrian Fabian about the black hole at its centre, whose strange behaviour includes emitting the lowest note that can be heard in the cosmos.
At an even greater scale, Jim encounters huge structures such as the Laniakea Supercluster, of which the Milky Way is only a tiny part. Then there’s the 'Giant Arc', a collection of galaxies that account for more than three per cent of the observable universe. Jim learns from its discoverer, British PhD student Alexia Lopez, that this gargantuan structure is forcing scientists to reassess their theory of how the universe evolves and may overturn some of the most fundamental principles in physics.

We love nature and all its glorious diversity. Some creatures we admire for their deadly beauty, others because they are cute, but for some it's hard to figure out exactly why we like them so much, perhaps it's a quirk. How do you decide nature's weirdest animal? Is it the sloth that hangs upside down and moves so slowly that moss grows in its fur? Is it a sea pen that sits rooted to the seabed in endless darkness and emitting its own glow? Could it be carnivorous snails that leave the ocean to digest dead creatures on the beach, finches that drink blood, or the tarantula that keeps a frog as it's pet. But with nature's endless variety, which is the weirdest? We can't decide. Can you?

Offering unprecedented access, Season 5 will once again take fans behind the scenes, to witness first-hand how the drivers and teams prepare to battle it out for victory in one of the sport’s most dramatic seasons to date.
The first episode begins with a recap of the closing laps of the 2021 Abu Dhabi Grand Prix controversy. After showing how important the relationship is between Guenther Steiner and Mattia Binotto for their respective teams, the 2022 Formula 1 season opens with pre-season testing at the Circuit de Barcelona-Catalunya. The teams and drivers all prepare their cars for the upcoming races. This year also marks the largest changes to the cars in many years.
Controversy arises when Haas F1 Team drops its major sponsor Uralkali along with its sponsored driver Nikita Mazepin due to the Russian invasion of Ukraine. Haas brings back Kevin Magnussen after he was let go from the team back in 2020. Current World Champion Max Verstappen finally makes an appearance on the show after having declined to appear in previous seasons. In the early races many teams, especially the Mercedes-AMG Petronas F1 Team, have to deal with issues of porpoising, a potential problem related to Ground Effect, which returned after having been banned in 1982. The first race, the 2022 Bahrain Grand Prix, is shown with both of the Red Bull cars losing power, Scuderia Ferrari achieving their first win in 910 days with their drivers Charles Leclerc and Carlos Sainz Jr. taking first and second place respectively and Kevin Magnussen achieving fifth place on his first outing back at Haas.

Mercedes' W13 Is put to the test at pre-season tests at Bahrain with Lewis Hamilton and new teammate George Russell behind the wheel. However, the car exhibits an incredibly unpleasant drive with an excessive amount of porpoising. The team has noticed the issue and plans to work on it before further tests commence. However, for Mercedes, the issue seems to remain unfixed. Indeed, the issues are present coming to the races at Imola, Spain, and Monaco, before arriving at the Baku City Circuit for Azerbaijan. Lewis' back starts to exhibit pain as he goes down the straights of Baku as Max Verstappen takes home the victory with Lewis taking fourth. After the race, the team principals convene for a meeting, where Toto Wolff of Mercedes expresses his dismay and concern about the safety of the drivers.
The Silverstone round, which also coincided with Zhou Guanyu's big crash coming into Abbey, finishes with Lewis Hamilton taking third place and Carlos Sainz Jr. taking his first career victory in Formula One. Lewis, having questioned the possibilities of retirement following the 2021 season, announces he is here to stay with Mercedes.

The first outing of the Miami Grand Prix is starting, and Ferrari looks to continue their successful streak starting from Bahrain and Australia into Miami. Ferrari's two drivers Charles Leclerc - who is leading the Drivers' Championship coming into the race - and Carlos Sainz Jr. lock out the first two rows of the grid. In the race, Verstappen immediately takes second from Sainz, and would take the lead by the ninth lap. Soon, McLaren's Lando Norris makes contact with Pierre Gasly of AlphaTauri, bringing out the safety car. Leclerc's old tires soon give him a disadvantage, which Verstappen exploits in his first victory in Miami. Leclerc finishes second ahead of his teammate.
As the season continues, Ferrari continues to make errors that end up costing their drivers the win; in Monaco, Leclerc leads the race as Sainz is brought in - but Leclerc, having been told to come in too, follows Sainz into the pits - only being told to stay out after he had already came in for his stop - handing Red Bull's Sergio Pérez the victory as Leclerc finishes fourth; in Baku, both Ferraris - Leclerc leading - retire due to mechanical failure with Verstappen winning; and in Canada, both Ferraris stay out again and are inconvenienced by their old rubber, handing Verstappen the win once again.
At a rainy Silverstone qualification, Sainz scores his first pole position in his career, and Leclerc, having spun earlier in quali, takes third. The race starts with a big crash for Zhou Guanyu, red-flagging the race. The race starts with Sainz, having retained his grid position, getting a good start; by lap ten, Sainz continues to control the field, but makes an error, allowing Verstappen to take the lead. However, the Red Bull driver reports a puncture and pits, allowing Sainz to take the lead again with Leclerc behind. Soon, the Ferrari pit wall tells Sainz to give the position to Leclerc as Esteban Ocon retires due to mechanical issues, bringing out a safety car. As Leclerc is told to stay out on his old tires, Sainz is brought in for fresh rubber. The race restarts and Sainz overtakes his struggling teammate for first, going on to win his first race in his career. Mattia Binotto, acknowledging the strategical errors made throughout the season thus far, resolves to fix them in the following races.

In his second year in the team, Haas driver Mick Schumacher faces a lot of pressure, which is not helped by a lot of expectations from being a Formula Two World Champion and being the son of a seven-time World Champion. The paddock travels to the Jeddah Corniche Circuit for the second running of the Saudi Arabian Grand Prix; as qualification for the race begins, Mick's run grinds to a halt when he suffers a big crash, ruling him out of the race due to the damage sustained to his car. Schumacher continues to struggle after Saudi; in Miami, Schumacher, in ninth place, collides with Sebastian Vettel, taking both drivers out of the race; he starts his Monaco run at the back of the field, only to lose it coming into the swimming pool section and splitting his car in half in the ensuing crash.
By the time the paddock has traveled to Baku, Magnussen has led the championship for the Haas team with 15 points against Schumacher's 0, and faces a lot of pressure over his future in the team. Schumacher starts the race in last place, while Magnussen rises up the field. However, Magnussen's race is stopped due to an engine issue, leaving Haas' chance for points in the hands of a slow-running Schumacher. Indeed, Schumacher is running very slowly to the point he is lapped by the leading Verstappen. Away from the track, Schumacher trains with his personal trainer, convinced he can still score points.
At Silverstone, Schumacher starts at the back of the grid, but the session is red-flagged due to a big crash for Zhou Guanyu, which the Haas drivers manage to avoid. Schumacher and Magnussen are due to start 16th and 14th, respectively. Schumacher pushes through the field - and with an overtake on Ricciardo, a DRS-assisted overtake on Vettel - and ultimately Verstappen, he ultimately manages to finish eighth - his first points in Formula One, sending the Haas pit wall into a celebration; Vettel and Verstappen also congratulate Schumacher for his efforts during the race. However, despite his efforts in the race, Mick's seat in the Haas team remains open.
