There are many things associated with this. But one thing never escapes our mind which is vanishing of ships and aircrafts once it enters Bermuda Triangle.
This lies in the western part of the North Atlantic Ocean.
Scientists believe that this happens due to very strong electromagnetic waves that forces ships and aircraft beneath the sea and pulls it down very deep onto the surface of the ocean. Even signals are lost in this process and hence no strong evidence has come till now even though scientists across globe are doing research on this.
One more thing- Believe it or not. The Bermuda Triangle had been described earlier in Rig Veda & Atharva Veda also.
