Light doesn”t travel at a constant speed in relation to time, spectrum waves have different speeds over long distances. Red waves travel at a different speed to violet. Pure white light has to be split into the 6 colors or the non visual spectrum, radio (yellow), microwave (orange), infrared, ultra violet, x ray (blue) and Gamma (green)

I Think 0 time is coming very soon, and we will start to go into reverse. Maybe the Maya were correct.

Once upon a time, time was different. Supernova explosions in the early universe appear to age more slowly than today’s supernovae, as if time itself was running slower back then, according to a recent series of astronomical observations. This cosmic time warp is exactly what should be produced by the expansion of the universe, confirming conventional big bang theory.

The article seems to answer your question.

Includes why Woody Allen’s mother was right. And why we can see light from galaxies that are moving faster than the speed of light.

Hawkings makes it clear that the expansion is indeed slowing. Seems to make it more logical that objects farther away from us are receding at the same speed as objects closer to us, but we haven’t measured that yet ’cause we don’t have anything fast enough to measure it with.

Or, as Paul suggests, the answer may just be 42.

That is not quite true in Intergalactic Explorer 6 since overflow:hidden does not trigger hasLayout. This only happens in Intergalactic Explorer 7 which is good since the Universal selector hack * html.doesn’t work unless quirks is triggered. We need to add a adjacent sibling selector to the equation. Maybe Intergalactic Explorer 8 can really solve this equation since it delves deep into these Atoms and analyzes the quirks ops quarks behavior. We can no longer solve the equation by hasLayout since is no longer present.

According to the laws of position:relativity or is that special relativity which give us the equation E = mc2. Appearing on this page is this.

Conservation of energy implies that in any reaction a decrease of the sum of the masses of particles must be accompanied by an increase in kinetic energies of the particles after the reaction.

This means that for an observer who is position:fixed any object that reaches the speed of light will have zero mass but infinite energy. In theory when the Big Bang happened mass was expelled form a singular point of no mass and infinite energy in all directions. Once matter begin to slow the energy would decrease but the mass will increase. This in theory would indicate that the expansion of the universe is decreasing or decelerating and must reach a point of time when expansion stops and contraction begins.

Unless I missed something, light over time can theoretically be impacted by black holes it passes by, which may distort the wavelength. One of the things I wonder when thinking about light moving toward us is what has it passed that may have impacted the perceived time, the actual wavelength, and the color shift accordingly. Can a black hole bend light to another spectrum?

I think your observation is very interesting and not one I had really thought of. I had posted not too long ago a topic regarding red shift which perhaps you may find interesting:

The cleanest way to apply this hack is by using the Universal selector hack (* html).

The question is… the universe… hasLayout?

For redshift to occur and object must be moving faster than the speed of light. If the universe is now in a contracting phase those galaxies that seem very far away are really just around the corner since theoretically the galaxies are moving towards us faster than the light that they emit.

Hope to speak to you soon before the bang!

This is the problem when using the dots on the expanding balloon analogy for cosmological expansion – the surface of a balloon is a 2-dimensional space expanding within a 3-dimensional context… the universe is a 3-dimensional space expanding within an even higher context (not sure how much higher, though).

So the cosmological red shift is in fact due to the stretching of space.

Now, that does not mean that objects in expand. As space expands, there is more of it – more room in which objects of the same size can exist. This expansion is driven by something that”s much weaker than gravity (whatever it is), which in turn is unfathomably much weaker than the weak interaction, in turn a lot weaker than electromagnetism, which finally is a good deal weaker than the strong force. (Gravity is considered 10^40 times weaker than the strong force; electromagnetism is 1/137th the strength of the strong force. In actual fact, this scale is a construct of fiction, as the forces cannot really be compared like that. But it”s a useful fiction nonetheless.) For something to expand as a consequence of the expansion of space, it would have to be unbound even gravitationally. Since the electromagnetic force (which is what”s responsible for nearly all structure we see at scales below the size of a planet) is unimaginably much stronger than whatever it is that drives the expansion of space, humans (and houses and tables and trees and rocks and blowfishes) do not expand just because space is expanding. The expansive force may be pulling things apart, but gravity, electromagnetism and the strong force pull them back.

After the distance have been established, one can inquire into possible relationships between distance and redshift. So it’s distance first, redshift second. Of course, if one has good confidence in the relationship, one can then use redshift as a proxy for distance, if one can be pretty sure there are no other causes for a redshift.

Next, redshift is determined by the shift of specific spectral lines, not just by a general reddening of the light. The only way those lines could change from early times til now is for something in the physics to change – most likely, some of the fundamental constants of nature. Whether or not such constants can change has been a periodic subject for debate and theorizing , but there isn’t currently any evidence or theory that has been widely accepted.

A redshift could also be observed, if the light from a distant object were absorbed and then re-emitted by an intervening body (i.e., a mass of gas). This could modify the redshift if the state of motion of the absorber were different from that of the emitter. So astronomers tend to inspect their spectra with care to try to rule confounding effects like this (e.g., intervening absorbers generally add other characteristic changes to spectra, which can often be detected).

This kind of work is amazingly difficult and painstaking, especially to establish the basic phenomena in the first place. But it does seem to be on fairly firm ground in general. I wouldn’t hang my hat on any exact estimates on the degree of expansion or contraction just yet, though.
