Since the discovery of the laser, science has been obliged to admit that there is no stronger force than light. Unfortunately, even this force can be used for evil as well as for good.
Many civilizations before ours had already achieved unbelievable things with light. Amongst many other discoveries, the Atlanteans discovered the laser beam, and they knew how to use sunlight to power their highly sophisticated machinery – everything was powered by light.
The only thing was that they abused their science and their power, and this was the reason for their downfall.
It is an inborn tendency of human nature to use everything to satisfy its baser instincts, such as cupidity and the desire to dominate. This is why, if humanity is not led by rational and enlightened beings who are capable of maintaining the balance between technology and morality, we too shall suffer terrible cataclysms like those that caused the disappearance of Atlantis.
