Taking a break from Aditya Hrdayam Series, posting this video that explains Time using Hiranyagarbha, the four dimensional spacetime. This is my son's contribution to Breakthrough Junior Challenge starting today. The challenge is to explain a science concept simplistically in 3 mins. He has tried to explain the concept of 'time' using Hiranyagarbha, the four dimensional spacetime. As part of Aditya Hrdayam Series, will be explaining the Hiranyagarbha suktam later. Please watch, share, feedback on the youtube video. -TBT
Cosmic Inflation Science says Big Bang created the energy of Universe, which was followed by 'Inflation/Expansion' of spacetime, in which spacetime expanded hugely. This is called 'Cosmic Inflation'. Think of a balloon that expands when air is pushed inside. Whatever exists on the surface of balloon uniformly expands along with surface of the balloon. So if energy/matter that was constrained and then expanded, then matter should be seen uniformly spread across the spacetime. But what we see in Universe today is different. There is a huge AkAsa, empty space of vacuum, everywhere. Then there are clusters of galaxies and matter sprinkled non-uniformly or non-homogenously in this AkAsa. How did this variation come about..? Can just bending of spacetime (gravitation) and the fusion reactions triggered by gravitation alone explain this non-uniform distribution of matter with huge empty spaces in-between..?
