Half the universe was missing... until now

Half of the ordinary baryonic matter has been tough to find but Fast Radio Bursts made it possible to detect the WHIM. Thanks to Kiwico for sponsoring this video! For 20% off go to kiwico.com/veritasium or use code VERITASIUM at checkout.

  • Is not clear to me the lightnings radiation travelling through the magnetosphere and getting back to earth? Thats matters to me more than loses baryons in the universe.

  • I don't understand why people are trying to include art in stem. They're fundamentally different in that stem subjects are all about indisputable facts and finding the best applicable method for a task while art is subjective and there is no correct "method" for making any sort of art.

  • the only problem with the sentiment at the end of the video is that the answer starys correct thia way... then again it is in the nature of scientists to keep questioning and some will keep trying to find even more mass to disprove whats known and unlock more secrets to demystify xD

  • Question: Why hydrogen bomb is more powerful than uranium based nuclear bombs

    Deepak RoatDeepak RoatVor Tag
    • Fission bombs work by splitting the atoms of a fissile material like uranium which creates an explosion that knocks away much of the material before it can undergo fission. Hydrogen bombs are more powerful because the way they use fusion allows them to use much more of their fuel making them much more efficient.

  • Can we really say those computer simulations were correct? If scientists keep developing new ways to detect matter and keep improving the current techniques then is it not possible that we might find more matter, thus providing the theoretical value of the amount of matter that should be present to be wrong?

  • Hi Derek. Thanks a lot for this episode. I’m a geneticist and I wasn’t aware of this proportion of baryonic matter vs non baryonic matter. It recalls me somehow the proportion of protein coding vs non protein coding sequences both in DNA (2%) and in RNA (2-7%). Fascinating. Seems that the matter you see is the lowest proportion of a bigger picture. Cheers.
