Hinduism does not oppose Science. It does not even oppose other religions. Science is a continuing effort to discover and increase human knowledge of the physical or material world through experiment and observation. But Hinduism has the force of providing answers to certain issues that Science could not.
The Lingam is shaped like an egg and represents the ‘Brahmanda’ or the cosmic egg. There are two types of Shiva Lingam. One is a black meteorite egg-shaped stone. It is said that such a stone is installed at Kabba in Mecca. The other one is man-made and is solidified mercury. Solidifying mercury is an ancient Vedic science.
Shiva Lingam represents the totality of the Cosmos and the Cosmos, in turn, being represented as a Cosmic Egg. Again an egg is an ellipsoid depicting with no beginning, nor end.
A glance at the image of Shiva Lingam shows there is a pillar with three marks and a Disc beneath it and sometimes with a coiling cobra snake around the Pillar and shows its fangs above the pillar. The truth behind the scientific research by the Danish scientist, Neils Bohr, demonstrates that Molecules (the smallest part of everything) made up of Atoms which consists of Proton, Neutron, and Electron, all of which play a vital part in the composition of Shiva Lingam. In those days instead of using these English words such as Proton, Neutron, Electron, Molecules and Energy, the ancient sages employed the usage of the words like Lingam, Vishnu, Brahma, Sakthi (which in turn is divided into Renuka and Rudrani), Sarppa, etc. as Sanskrit was the dominant language in those periods.
According to Hinduism, the Pillar is described as the column of fire which represents the three Gods – Brahma, Vishnu, and Maheshwara while the Disc or Peedam represents Sakthi. The Disc is shown with three ridges, carved at its periphery.
