WE SAY THAT THE TIME AND SPACE IS A FORM OF LIGHT,(SAID BY FAMOUS SCIENTIST- STEPHEN HAWKINGS)
AND THIS IS PROVED EVEN THROUGH THE CONE LIGHT OR THE WATER RIPPLE THEORY.
SO THE QUESTION GOES LIKE, IF THERE IS NO SOURCE OF LIGHT OR WE SAY THAT 0 AMOUNT OF LIGHT THEN THERE SHOULD BE NO SPACE OR TIME IN THE GIVEN REGION.WHY IS IT SO, AND IF IT IS, THEN THERE SHOULD BE NO SPACE AND TIME IN A TOTALLY NON LUMINOUS ROOM, BUT IT IS NOT LIKE THAT.WHY?
ACCORDING TO STEPHEN HAWKINGS TIME AND SPACE ARE A FORM OF LIGHT(PROVED BY MANY EXPERIMENTS) SO, THERE SHOULD BE NO TIME AND SPACE IN A TOTTALLY NON LUMINOUS ROOM. BUT AS OBSERVED IN DAY TO DAY LIFE, THERE IS NO SUCH PHENOMENA BEING OCCURED IN SUCH CONDITIONS . IF SUCH A GREAT SCIENTIST HAS SAID THIS THEN THIS SHOULD BE APPLIED ON THE DOMESTIC LEVEL.BUT IT IS NOT, WHY?

Light spectrum is not only consisted of a visible light spectrum but also electromagnetic (EM) radiations (ultraviolet rays, infrared waves, gamma rays, X -rays etc.).
Dark room does not have visible light but will it be free from EM radiation? If a mobile phone kept in the dark room will it not work?
There is no place in the universe that is free from EM radiation.
Cosmic Back ground radiation, radiation in the micro wave range are present every where in the universe and discovery of this radiation confirm the big bang theory of universe
