A Kurzgesagt animation walking through how a Mars base could be built and why it would be punishing, covering radiation, temperature extremes, toxic dust and the need for shielding.

A Kurzgesagt animated explainer on whether aging could be cured within our lifetimes, made with Lifespan.io and the LEAF foundation. It introduces the idea of treating aging as a medical problem.

Kurzgesagt explains the Holocene or Human Era calendar, which adds 10,000 years to the current year to anchor dates to the start of human civilization. It argues this gives a more sensible frame for human history.

A Kurzgesagt video arguing that social media's problem is information flooding and tribal polarization. It suggests a return to smaller online communities and more in-person interaction.

Kurzgesagt examines who is responsible for climate change, comparing historical, current and per-capita emissions by country. It argues that individual footprints are a distraction from larger responsibility.

Kurzgesagt explains why humans feel loneliness, its evolutionary role, and how modern life can turn it into a harmful downward spiral. It cites research and offers ideas on what to do about it.

A short Kurzgesagt animation explaining the Great Filter, the idea that finding alien life might be bad news because it implies something usually destroys civilizations. It connects the concept to the Fermi paradox.

Kurzgesagt explains how the European Union is governed, how its officials are elected or appointed, and whether a citizen's vote actually matters.

A Kurzgesagt animation giving a big-picture tour of the human immune system, its organs, transport network, and the cells it produces every day. It accompanies their IMMUNE book.

A Kurzgesagt animation about how the immune system constantly detects and kills cells that are turning cancerous. It explains what cancer cells are and why stopping them is so hard.

A Kurzgesagt animation of how the immune system responds to a bacterial infection, depicting immune cells as an army defending the body.

A Kurzgesagt video on the conditions in which most farm animals are raised. It argues that cruelty is for cheaper rather than better meat, and that a small price increase per meal could avoid most of the suffering.

Kurzgesagt's animated explainer on the human immune system, describing the body as an ecosystem and how immune defenses cope with the variety of invaders. It promotes their book Immune.

Kurzgesagt examines how AI-generated content is flooding the internet, from video and music to news and books. It looks at how this makes verifying what is real harder.

Kurzgesagt's animated explainer on CRISPR gene editing, covering how the technology works and what it could mean for curing disease, designer babies and aging. It frames genetic engineering as an irreversible change coming to humanity.

Kurzgesagt introduces the Fermi paradox: with so many stars and planets, why do we see no sign of aliens? It sets up the question and what it might imply for our own future. It is part 1 of 2.

A Kurzgesagt explainer asking whether organic food is really healthier or better for the environment. It defines what organic means and looks at pesticide use, nutrition and environmental impact, with sources.

A Kurzgesagt animated explainer on the climate and environmental cost of meat. It covers how beef drives deforestation and emissions, and how this compares with plant-based foods.

A Kurzgesagt animated explainer on meat: why people love it and what it costs animals, the environment and health. It lays out the complicated trade-offs of meat production and consumption.

A Kurzgesagt animation on South Korea's record-low fertility rate and rapidly aging population. It explains why a demographic collapse looks hard to reverse and projects the population shrinking sharply by 2060.

Kurzgesagt explains black hole stars, a hypothesized kind of giant star with a black hole at its core that could be a route to early supermassive black holes.

Kurzgesagt's animated overview of human origins and the vast prehistory before recorded history. It covers how modern humans emerged and spread.

Kurzgesagt explains the black hole bomb and how far-future civilizations might extract energy from spinning black holes, including Dyson-sphere-style ideas.

Kurzgesagt explains why, even with science-fiction technology, most of the universe is permanently out of reach because of cosmic expansion and finite resources.

A Kurzgesagt animated explainer on how humanity could build a Dyson sphere, a swarm of structures capturing the sun's energy. It covers using Mercury's materials and a step-by-step construction approach.

Kurzgesagt explores the idea that black holes could create universes and that we might live inside one. It builds up the physics of how density falls as black holes get larger.

Kurzgesagt explores the idea that life might have arisen shortly after the Big Bang, when the whole universe was warm enough to be habitable. It discusses what that would mean for the origin and spread of life.

Kurzgesagt asks whether advanced civilizations could have existed on Earth in the deep past and left little evidence. It looks at time as a dimension for searching for alien civilizations and the limits of the geological record.
