Inner Nature: Forces of Nature
By Vidya Rajan, Columnist, The Times
The story so far: The hot, dense singularity that was the source of the Big Bang exploded about 13.8 billion years ago (bya) and the energy in the explosion spread, cooled and became lumpy. The lumps were matter (~5%), dark matter (~25%), and dark energy (~70%).
To break it up into timelines after the instant of the Big Bang (A.B.B.):

The Earth rotates once on its axis every day, with the resultant periodicity of night following day. The predictability of exposure to the energy sources of light and heat have allowed lifeforms to evolve mechanisms to harvest it during daytime and develop materials to store that energy. All energy that emanates from the Sun is in the form of electromagnetic...
