In this article we compare Kerr spinning black holes and microscopic wormholes with tunnels in near-death experiences. Kerr rotating black holes are traversable. According to Heisenberg's uncertainty principle all physical quantities fluctuate randomly. Microscopic wormholes are created in the quantum fluctuation of vacuum ( J. Wheeler spacetime foam ). We consider points of similarity between Kerr spinning black holes or Microscopic wormholes and confirm following points of similarity.
① Both Kerr rotating black holes or microscopic wormholes and tunnels in near-death experiences are sphere and dark.
② As Kerr spinning black holes form vortices, so create tunnels in near death experiences vortices.
③ Both vortices of rotating black holes and vortices of tunnels in near death experiences draw in.
④ Microscopic wormholes and tunnels in near-death experiences are common in that both are created in the quantum vacuum. According to Heisenberg uncertainty principle quantum wormholes exists fleetingly. The wormhole throat opens out only for a limited duration, after which it closes up again. So something has to pass through wormholes faster that light. Mouths of tunnels in near-death experiences also open out and close up. And neardeath experiences also pass through tunnels faster than light.
⑤ Spinning black holes and microscopic wormholes are both short cut gateways to another universe or links two widely separated places in the same universe. Tunnels in near death experiences are also short cut portals to another universe or link two remote points in the same universe.
⑥ As wormholes can be used to travel the future and back to the past, so near-death experiences can travel the future and back to the past.
