    What is an Alien Megastructure?

    Alien megastructures are back in the headlines after some new research published last week. It has been claimed that Tabby's Star is confirmed to be steadily dimming, which is completely unexpected behavior for a star. Prof Kipping explains what we know (and don't know) about this mysterious star and what astronomers really mean by "alien megastructures".::More about this Video::► Montet & Simon (2016), "KIC 8462852 Faded Throughout the Kepler Mission": http://arxiv.org/abs/1608.01316► Schaefer (2016), "KIC 8462852 Faded at an Average Rate of 0.165+-0.013 Magnitudes Per Century From 1890 To 1989": http://arxiv.org/abs/1601.03256► Boyajian et al.

    The Strangest Idea in Science: Quantum Immortality

    Use code coolworlds at https://incogni.com/coolworlds to get an exclusive 60% off an annual Incogni plan.One of the leading interpretations of quantum theory is that every probabilistic event leads to a branching of reality, where all possibilities occur. This "many worlds" interpretation has been growing in prominence, but it implies a bizarre consequence. It might mean that you can never die, and will continue to survive not only life threatening events but even old age. Join us today as we explore the extraordinary idea of quantum immortality.Written & presented by Prof. David Kipping.
