Invisibility cloaks are taking baby steps from science fiction to science fact. But there's an even stranger and more incredible possibility - an invisibility cloak that works in both space and time, shielding whole events from history itself. The basic idea is surprisingly simple.
An Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship can ride the wave to accelerate to high speeds and time travel. The Alcubierre drive, also known as the Alcubierre metric or Warp Drive, is a mathematical model of a spacetime exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "faster than light" (although not in a local sense - see below).
Some sharks, as well as tuna, swordfish are all semi-warmblooded and maintain high core temperature in critical areas, like tail muscles, using reta mirabile. Pinnipeds and cetaceans have flukes and extremities that are in contact with cold water, and still need to use reta mirabile to prevent cold shock as they inhabit waters that can be below 0 C. You actually probably have a point about why tuna and swordfish and white sharks are restricted to warm-ish waters- they simply can't maintain homeostasis in arctic waters, hadn't thought of that.
