Science, especially Cosmology needs multiple view points a.k.a theories. Whether hey are testable or not is for the future generations. Floating a theory, however outlandish it is, shows the design of the human intellect and imagination. Many conjectures in Mathematics are yet to be proved. Fermat’s last theorem has been proved only recently. Like Law, an accused is not guilty until proven, should be applied to Cosmological Principles. Every Professor will have his pet theories and Dr. Paul Steinhardt is no exception. Stephen Hawking asserted that nothing escapes from Blackhole, but he observed the radiation emanating from a blackhole, which was later termed as Hawking Radiation. Even if we sum up all the humanity’s total intelligence and apply it to cosmology, still it will be short by 95% as most of our laws are tried in the visible spectrum only. We hope that some spark like a Big Bang will occur in the sub conscious state of human mind which may explain the state of nature. Incidentally, the Rishis of East have been advocating that one needs to look inwards to understand the outwards.

The energy that is compressed in a tiny ball which exploded in a minuscule of time frame and still expanding after 13.5 billion years, equals a myth only. Why can’t we have a re-look at the Oscillating Universe and a Steady State Theory of Fred Hoyle and Jayant Narlikar. The Hindu Scriptures like Surya Sidhantha, abhorred by Science incidentally, points to one such mechanism of birth, death and rebirth of epochs of 4 YUGAS, called 1 Yuga cycle which is 4.32 million years. These Yuga cycles repeat many times (72 million times) and last for many trillion years(311.04). A food for thought.
