A war has been raging for billions of years, killing trillions every single day, while we don’t even notice. This war involves the single deadliest being on our planet: The Bacteriophage.

In future, it might become possible to simulate entire universes. But if this an option, how can we know that it’s not already happened?

The observable universe is a big place that has been around for more than 13 billion years. Up to two trillion galaxies made up of something like 20,000 billion billion stars surround our home galaxy. In the milky way alone scientists assume there are some 40 billion earth like planets in the habitable zone of their stars. When we look at these numbers it is hard to imagine that there is nobody else out there.

So what is the difference between you and a rock? This seems like an easy, even stupid question. But even the smartest people on earth have no idea where to draw the line between living and dead things. Which leads to mind-blowing implications. What is life after all? And is death really a thing? Lets look into it together.

Humans. We have been around for a while now. When we think about our past we think about ancient civilizations, the pyramids, stuff like that. But this is only a tiny, tiny part of our history.

The sun. Smooth and round and peaceful. Except when it suddenly vomits radiation and plasma in random directions. Should we be worried?

Humans are proud of a lot of things, from particle accelerators, to poetry and pokemon. All of them made possible because of something humans value extremely highly: intelligence.

Humans love to explore. Strangely enough even horrible places – like Mars. Let’s see how building a Mars base could work and how insanely nerve-wracking exactly it would be.

Everybody feels lonely sometimes. Why do we feel this way and what can we do about it?

Consciousness is perhaps the biggest riddle in nature. In this video we explore the origins of consciousness and take a closer look on how unaware things became aware.

Are wormholes real or are they just magic disguised as physics and maths?

With the breathtaking explosion of innovation and progress, for the first time in human history the concept of leaving our flesh piles behind and uploading our minds into a digital utopia seems possible.

Throughout history, the definition of beauty has changed a lot. But beyond individual and contemporary tastes, some things have never really gone out of fashion. Here’s another video by Kurzgesagt.

Living things need a lot of different materials to keep themselves going. And they somehow need to transport them from the outside to the inside.

For some two million years, the lives of our ancestors basically remained unchanged. It was around 20,000 years ago that the behaviourally modern humans began a process that would change our lifestyles forever.

People who are grateful, no matter what for, tend to be happier and more satisfied.

We present you with another video by After Skool.

Each of us sometimes looks at the starry sky at night. Have you ever thought about which stars are the largest in the universe? Here is the answer from Kurzgesagt.
