Conch shell sounds and its science

In Mahabharata, conch shell's had a significant place. Arjuna's shankha was called "Devdutta", Bhima's "Paundra", Yudhisthira's "Anantavijaya", Nakula's "Sughosa" and Sahadeva's was known as "Manipushpaka. Conch shell's significance can also be corroborated by science. If we try holding a shankha near our ear, the sound of the gently humming ocean can be heard. This is actually the natural vibration or cosmic energy of the Earth which gets magnified on entering the conch shell.

The vibrations from these conch shells can overpower evil forces from the Earth and at the same time also clear environmental pollution including healing the hole in the ozone layer which causes global warming. Blowing a conch shell enhances the positive psychological vibrations such as courage, determination, hope, optimism, willpower, etc. in the blower as well as those around him.That is why a conch shell is blown during sacred rites to get rid of negative energy.

Time dilation

Time dilation is very much evident in Mahabaratha. "Bhishma Pitamaha" of Mahabharata was gifted with a time control to end his life. He served his dynasty for many of his following generations becoz of this.
Mystical Travels

Einstein through his special theory of relativity gave the concept of time dilation for a body moving comparable with the velocity of light which is said to be constant and same throughout the universe and during relative motion also.

Mahabharata tells the story of how the Naga princess Ulupi abducted Arjuna while he was bathing in the Ganges River. Ulupi pulled Arjuna down not to the riverbed, as we would expect, but into the kingdom of the "Nagas" (celestial snakelike beings), which exists in another dimension. Mystical travels explains how the worlds of super humans (devas) are connected with our world.
