Ujil,
You tend to analyze physical phenomena in perspective of philosophical, spiritual, using human emotions, and humanly observations ( meaning humans are part of whole physical interractions as if we play part in speed of light, gravitation force or in any other natural forces etc). The role of humans here is just to observe and conclude intellectually what might, or is happening. You do not have to burn yourself to see or feel like how sun is burning. We have emotions, senses, intellect, understanding which matter or physical substances do not have. We are just trying observe, collect date, conclude, study the present and predict both future and past. We have no role whatsoever in this universe for the things that are acting the way they are. You do not have be a photon to observe how photon acts. Its just plain simple observation, data collection and conclusion without disturbing the system. Matter fact, we are part and product of this universe and time ( Universe, galaxies, stars, sun, planets, earth, water, minerals, DNA, Bacteria, invertebrates, vertebrates, mammals, monkeys, humans a.k.a universal evolution)
Here we are talking about physical forces, physical interractions physical phenomenas.
The universe was always there before humans evolved, before biology evolved ( biological interractions) started, even chemistry evolved ( chemical interraction). Atma, brahmans are created by humans. A dead chicken is dead as a rock. It will decay, transforms into biofuel eventually becomes a fossil fuel which is petrol. If you dig deep inside, you are just a composition of C,H,O,N, etc with intellectual mind, product of evolution which took billions of years to get here. We can fly a plane, take a robot to Mars, transplant a heart,while our close hereditary relative, Monkeys are still climbing trees.
Spiritual ?religious thoughts are end result of our intellectual brain. We were nothing before we were born and will be nothing after the death. Only us as a animal are intellectual and want meaning of life. Meaning of life is to live and we are only living because we are not dead if that makes sense.
Now lets understand infinity. A length of scale/ruler is finite. You have a starting point and ending point. Speed of light is finite. A photon starts from point A and travels to point B in one sec. You measure distance divide by time, you get the speed. The distance of earth and sun is finite. You have point A to start and Point B to finish. Both can be marked in in real-time and space. But space does not have starting or ending point. Its just there. Like numbers if you say, a finite set of numbers ( 1-100000) then its finite. But there is not limit on when or where we can start or end numbers. Likewise, Observable universe has finite space it has occupied. The space that has not been occupied by matter or energy is still space whether there is photon/matter/energy present or not. When photon reaches there then it becomes part of observable universe's space.
Infinity basically means no boundaries. You can keep on going, stop somewhere and make a boundary, but if you want to travel further there is no boundary because the extension itself does not have boundary.
Would space have boundary?
No, it is extension of three dimension where matter/energy interracts. Lets start a journey from sun, photon gets to galaxies and more galaxies, finally reach to end point of universe, as it reaches the end of observable universe, space still exists beyond that point but now photon will travel through through space beyond observable universe before. So, there was a finite universe in finite space, the very moment photon travels through that boundary, the universe expanded through space. Space was always there before the photon reached there.
