The Solar Step Universe

Have you ever looked at night sky with a pinchful of curiosity? The moon,the stars,the constellations and all those so called heavenly bodies! It is often said that when we are looking at the night sky, we're looking back in time. It is absolutely true.  Speed of light is 300,000,000m/sec. This means,if I wave my hand a meter away from you, you'll see me waving my hand 0.000000003 seconds later. It is true that this much time is so so so little that we'd never feel it. But when things come in space and distances lengthen, everything is quite confusing and equally beautiful! You'll see a guy waving his hand 3,000,000kms away from you after 10 seconds! There exist objects in universe that are far from us more than these numbers. There might be a planet out there from where a person(sort of an alien)(if they exist) would have been watching your first birthday through his/her telescope. Some people say time travel is possible if we could move with speed of light...

Humans have curiosity about their origin since time unknown. Ancient humans observed the rains,the thunderstorms, the fire and the seasons which made them think about why they occur. Here come out two ways of thinking. One,(quite simpler one) GOD did it. Two,(quite harder one) We'll have to THINK. Everyone must ask questions and try to find their answers. But how did this great quest for knowledge begun? In older times (even before the birth of Christ) there used to be flocks of philosophers of various thinking streams. No one will call us wrong if we'd say these philosophers were early physicists. They used to regard works to be done by using own hands to be less sacred. This is the reason why Chemistry and even experimental physics were born after theoretical physics. As you and me are living in modern times,it becomes quite harder to believe what I just said. How can one propose a scientific theory without any experiments? But they did! They'd just sit in a armchair, fly...
