In a world where nothing seems to ever work out as you had hoped, The Rehearsal features Nathan Fielder helping ordinary people rehearse difficult conversations or life events through the use of sets and actors hired to recreate real situations. The situations can be trivial, like confessing to a lie about educational history, or more complex, like raising a child. Fielder commissions extravagant sets with every detail recreated. He hires actors to inhabit these sets and practice different dialogue trees with his clients dozens of times. Information used to train the actors and build the sets is often collected without the subjects' knowledge.
In the firs episode, Nathan Fielder helps Kor Skeete, a Brooklyn-based trivia aficionado who wants to confess to his bar trivia team that he lied about having a master's degree. Nathan reveals an elaborate method of rehearsals involving an actor (K. Todd Freeman) playing a 'fake Kor'. To help Kor rehearse the difficult conversation with his teammate Tricia to clean this long-held lie, Nathan creates simulations of trivia night with a fake Tricia in a full-scale replica of the Alligator Lounge, a Brooklyn bar. Kor overcomes his fears and makes his confession to the real Tricia.

The idea of intelligence is explored in the concepts of computers (using bits as their basic units of information), whales (in their songs and their disruptions by human activities), DNA, the human brain (the evolution of the brain stem, frontal lobes, neurons, cerebral hemispheres, and corpus callosum under the Triune Brain Model), and man-made structures for collective intelligence (cities, libraries, books, computers, and satellites). The episode ends with speculation on alien intelligence and the information conveyed on the Voyager Golden Record.

The series tells stories of people caught in the dark and twisted web of modern misinformation and digital deception. Haunting, bizarre and up-to-the-moment relevant, the series explores consequences of 'SWATing', takes a chilling trip down the rabbit hole of white supremacy, joins a Federal hunt for the suspect of a brazen IRS heist and dives into Russian election interference.
In the first episode, when an online gamer makes a series of fraudulent 911 calls to lure SWAT teams to innocent people's homes, his targeted trickery turns to tragedy.

The white hole is a region of spacetime and that cannot be entered from the outside, although energy-matter, light and information can escape from it. In this sense, it is the reverse of a black hole. Einstein predicted strange cosmic phenomena known as white holes, but scientists have yet to prove they exist.
Today, astronomers race to find the clues that can unlock the secrets of white holes. They investigate the tiny black holes that hide in the most ancient parts of the universe to finally find the smoking gun.

For all of human history, the Sun, our home star, has measured our days and our seasons while fueling all life on Earth. Yet it remains an enigma. NASA's Parker Probe Plus is on a mission to change that, flying through dangerous radiation to become the closest spaceship to orbit our Sun.
It's a journey to the center of our solar system, a mission to gather information about the most critical celestial body in the sky, our star.

The way that wars are fought is constantly evolving. In the warfare of today and the future, it's the push of a button rather than the pull of a trigger, bringing disorder without a single soldier setting foot on the ground. The real-world battlefield has morphed from the bloody trenches of the front line into an age of cyber warfare. From collapsing all the infrastructure of a country to changing minds for elections, any threat you can imagine can be done.
