The suction speed of an elephant's trunk is 330 miles per hour

That's as fast as a bullet train in Japan.

    ​Dyson spheres: The key to resurrection and immortality?

    Creating an afterlife—or a simulation of one—would take vast amounts of energy. Some scientists think the best way to capture that energy is by building megastructures around stars.

    • In a 2018 paper, researchers Alexey Turchin and Maxim Chernyakov published a paper outlining various ways humans might someday be able to achieve immortality or resurrection.
    • One way involves creating a simulated afterlife, in which artificial intelligence would build simulations of past human lives.
    • Getting the necessary power for the simulation might require building a Dyson sphere, which is a theoretical megastructure that orbits a star and captures its energy.
