an electron from a source. Where will it go? If I fire a bullet from a gun in a given direction at a given speed, I know where it will be at a later time. But I cannot make such an assertion for the electron.

It may be here, there, anywhere. I can at best quote odds for it being found in a specified location at a specified time.” “The lack of determinism in quantum theory! Even an ignoramus historian like me has heard of it,” Professor Gaitonde said. “So, imagine many world pictures.

In one world the electron is found here, in another it is over there. In yet another it is in a still different location. Once the observer finds where it is, we know which world we are talking about. But all those alternative worlds could exist just the same.” Rajendra paused to marshall his thoughts.

“But is there any contact between those many worlds?” Professor Gaitonde asked. “Yes and no! Imagine two worlds, for example. In both an electron is orbiting the nucleus of an atom...” “Like planets around the sun...” Gangadharpant interjected.

“Not quite. We know the precise trajectory of the planet. The electron could be orbiting in any of a large number of specified states. These states may be used to identify the world.

In state no. we have the electron in a state of higher energy. In state no. it is in a state of lower energy.

It can make a jump from high to low energy and send out a pulse of radiation. Or a pulse of radiation can knock it out of state no. into state no. .

Such transitions are common in microscopic systems. What if it happened on a macroscopic level?” Rajendra said. “I get you! You are suggesting that I made a transition from one world to another and back again?” Gangadharpant asked.

“Fantastic though it seems, this is the only explanation I can offer. My theory is that catastrophic situations offer radically different alternatives for the world to proceed. It seems that so far as
