The facts that we know, or think we know are that: when we look out into space we are looking backward into time. Why because the distances are so vast and that light takes a long time to travel between stars. The light from the sun is 8 seconds old when it reaches Earth. The light from Jupiter and Saturn and the outer planets is minutes old when it reaches us.
Scientists would like us to believe that light travelling through the Universe bends due to the gravity effects of galactic clusters and dark matter, so here for the scientists is a new thought.
If in looking out into space, though Hubble or some other technology, how would we know whether or not we were looking at our own galaxy sometime in the past.
We would not recognise our own sun, nor would we recognise our own Solar system which was probably different in structure several billion years ago. Our planets would not necessarily have the same number of moons, and their distance from the sun would be influenced by the effects of gravity within the solar system and by the effects of gravity outisde our solar system.
Would our Galaxy still be the same shape 8 billion years ago, or 4 billion years ago, compared to its current shape and existence. The further out we look the farther back in time we look. The question being, would we recognise our own galaxy if we saw it?
Man has had such a short time in the Universe, we are arrogant to assume we would recognise an earlier version of our galaxy in a Universe we don't understand!!!

The Speed of Light and other spacial anomolies
Einstein the father of E=Mc^2 was revolutionary, he was a post-modernist in taking the view of what would it be like to sit inside a ray of light as a new perspective.
From his thinking comes the notion that as as an object approaches the speed of light it will become heavier as it approaches speeds closer to the speed of light. The implication is that it would become infinitely heavy at the speed of light, and so need an infinite amount of energy to allow it continue, let alone go faster. The further implication is that such an object of infinite mass would in fact become a black hole, with infinite mass from which no light could escape. Other factors that would be seen by an observer, if Einstein is to be believed is that the object would get shorter as light speed was being approached, the implication being that at light speed the object would be infinitly short, perhaps even looking somewhat like a singularity.
Further implications of this is that if an object of any mass travels near or at the speed of light, its mass will increase to infinity the faster it goes.
So what of light itself. Does a photon of light have mass? If light can be bent by the gravity of dark matter, or of large galactic clusters, then must it have mass, or is the light itself being delected by the supposed gravity holes created in Einstein's model.
Light itself is composed of energy, it must have had a certain kinetic energy that is converted to momentum when the light itself is created in a sun or through whatever stellar or otherwise phenomena created it. If it holds some sort of energy, how is it stored? How, for instance can a photon exist for some 13 billion years without deteriorating, although light is known to dim. How can a particle of light exist in order to travel across the universe and be seen by us on planet Earth sometime later?
Returning to the previous notion of light having mass.
If light has some mass at all, then as light which travels at the speed of light, then by implication it must have infinite mass and so become a black hole. Simply then, light should, according to Einstein have infinite mass and take an infinite amount of energy to move. So what of the photon, that holds lights energy? What is the photon? Is the proton a small black hole that perhaps emits light? Or is it something else? Maybe light is not what we believe it to be.
Is there a link between light and what we call gravity. Is light the source of gravity, and our understanding or lack of understanding of gravity based on our perception of the effects we see and experience.
