I am not a scientist either, it's just a topic to discuss how people view these sort of things. If we don't talk about it, we won't know!!!

Thank u @BestCaseScenario. I am wondering about time though!!! another poster said light is a measure of time but not time itself. This makes sense because the sun-rays reach our earth whereas the rays of another star seems more distant. So is time a measure of distance? because if I take a car right now and go 1 kilometer in distance, I can reach there quicker then if I was walking yet everything around me is still the same nothing changed around me only the fact I went quicker!!! So the sun-rays if measured u could use that as base to see how long it takes to reach the earth and then move the sun further and further away from us to the most distant stars location untill you recognize the rays being emitted are the same and u can quickly work out what distance your looking at!!! But that sort of time is more about distance and I don't think this the true time at all but more of a measure of how far things are in distance only from us!!!
I hope I am looking at this correctly, any corrections would be appreciated and if someone can actually explain true time the actual ability to move, what gives that light the ability to even move across space that is nothing to do with the distance they are from earth!!! Now I know light bends and twists depending on cosmic conditions just like it bends and twists on earth depending on objects in it's path.
DrOsman, The poster will tell us what he meant by light being a measure of time. It is true that How fast/how long it takes the light of an object to reach earth depends on the object's distance. There will be a gap between seeing that light from earth's vantage point and when that light was released by the stars. Many of the stars you are looking at are dead long ago and don't really exist right now. What you see is not CURRENT. Only reason you see them now is because of how long their light took to travel and reach your eyes/earth. Interestingly, looking up at the sky is actually looking back in time or history. I think I mentioned this how this is the method by which they calculated how long the big bang happened, which was the creation of the Universe . They calculated how far the furthest stars are using their luminosity/brightness and the method of parallax . The past is up there in heaven and we are relatively new as human beings on earth. This jives in well with the Quranic story of Allah creating Adam after earths/heavens and everything else was already in existence long ago.
I am headed outside home right now, so I suggest you watch some videos about:
- Relationship between space and time
- Newtonian definition of Time
- Is time absolute or relative
- What is time?
- What is space?
- What is light?
Take notes and let us trade nuggets. I will do the same. It is very complex subject and my knowledge is very limited. I will share what I learned. Others with physics background can join also.
I haven't watched any documentaries on it yet. I am trying to find a good one, if u have any suggestions please provide. A-lot of what I seen on youtube is speculation and not concrete!!! I have a question for you, if we are looking back in history through space using the stars, how do we determine that? is the last source of light or star in space the determination? can space still exist without light or stars? I honestly think space is independent of light, wat if the last light we see isn't the last one and appears to be? becuz space itself could continue beyond with no light and who knows after a long distance there might be more lights and stars!!!
What we could be seeing is intervals of space like swimming lanes in a pool, u might see one lane doesnt mean those other lanes aren't there. Hence why it's important to settle the matter of space and time itself and i dont mean the time of distance n speed but the time where space is actually expanding and moving.
A good experiment would be to see if the laws of physics still apply to even places where there is no matter like planet, stars, etc. Just a piece of dark space with nothing. If there is still the same laws present, then we know what we see isn't the full story of the universe and there is invisible things at play. If we can conclude there is no physical laws present there in those areas of dark space it can then help explain why it's dark place with no matter as the conditions aren't there for matter to arise!!! Kinda of like why a desert is a desert, there is no rain, the conditions for fertile land is simply not possible due to the conditions that piece of land is enduring. Could the space be a similar story? where there is patches of the right cosmic conditions and other areas don't have it and it's therefore dark!!!
I hope some of the brothers who studied physics, would come in. I never studied it, I just started to gain some interest in it the past few days. I must say though, I am not at all interested in the numbers and equations so save me that!!! unless it's simple like energy = mass
Space here is a mathematical construct which we use to explain phenomena. For example throwing a ball falling is said it be falling through space to explain what is occurring.spafe is defined to be a flat plane which is charectarised by physical laws. For example space bends in the presence of gravity , warps to keep the law of a constant speed of light and etc.Well I know understand how planets bend space, but I still argue that space outside of that planet is not bended. The shape of the earth being round is obviously going to bend the shape of the space around it to be round. The bigger the planet obviously the bigger the bend of space and the smaller the planet the smaller the bend will be.
I see it like this now, you got all this black space going every direction and then you put a ball in there, obviously the space around that ball will curve around it. But that curvature is due to earth shape and it's impact is on earth not the surrounding space at all. The other thing I am confused about it is regardless how heavy earth is, it shouldn't cause a dip on space like this, because space is weightless so no matter how much earth weighed it shouldn't cause dips like that.

Space doesn’t have mass as it isn’t characterised as an object in our universe rather a plane, for example think fondly it like a canvas. You draw pictures on the canvas and then you keep the picture and throw away the canvas. You can still assume there is a canvas there and thus explain all the phenomena by assuming the canvas exists.
Space is a construct , it being “ real” doesn’t mean it’s affected by mass etc.Space is real bro, it's not a mathematical equation. How it operates may-be or came to be might be. But space is clearly visible and observable at night. And obviously I don't look as it as an object either. Anyways I am reading up on hawkings first few chapters and might clear up my misunderstandings but if I can't reason it to myself, I won't accept it!!!
DrOsman, Space(in Astronomy) is defined as an area outside Earth's atmosphere and it starts from what they call the Karman line 100km Above sea level. As Canjeero alluded to, space is a construct, a concept people agreed upon with sets of defined boundaries and characteristics. It has objects floating in it, its environment is different from eath's. It is filled with radiation and celestial bodies. That is what space refers to. Earth is part of Space from a different vantage point. If someone was looking towards earth from mars or Jupiter, they would view earth as part of space. A planet with life and good environment.
There is one picture - an artist's render that captures what Space is according to Astronomy:
From explosion to expansion, left to right, this picture captures space and everything in it based on Astronomy. Earth is somewhere there insignificant in size.
But gravity is funny thing, regardless how much something weighs, it will always be restricted to a constant speed. So you could take a feather into space and the biggest object on earth and it float at the same rate but the second it doesn't have 'weight' like light it goes so much faster. This is so illogical, you would think the bigger or smaller something is there would be a difference in how fast they go but that's not true cause we saw the test in the moon of a feather and hammer!!!
Something could weigh 0.111111 of a kilo and it's subject to the laws of gravity!!! but the second it doesnt weigh anything like light, it can zoom past like there is no time like when u turn on your car light and it's already covered a great distance before u even moved!!!
I think it was a steady expansion more then an explosion. If you blow a balloon to hard it will fall in on itself, but a steady blowing it can grow. That's if the big bang is true!!! I have my suspicions!!! I don't disagree anything 'big' usually has small origins though. Logically that is true, but the universe isn't logical in it's design!!!
Yes, an explosion then a steady expansion. The Big bang theory was derived from the realization in labs that the Universe is expanding at a fast rate. People working in Observatory labs noted changing positions of galaxies in linear fashion. Edwin Hubble, an American astronomer made the discovery in California Observatory after he measured the red shifting of many galaxies. With the realization and verification of an expanding universe, came the idea of the universe having been small in its beginning. It became a race of finding out how small it was before it expanded. Hence, the single point origin of the Universe, Big Bang being its birth.
In the Quran(though I am not using it here as a science book), made an indirect reference to the one point origin of earth and heavens, and to the expansion.
"The heaven, We have built it with power. Verily. We are expanding it." And "Do not the Unbelievers see that the heavens and the earth were joined together before we clove them asunder? We made from water every living thing. Will they not then believe?"
