What do you thing of this paper http://arxiv.org/abs/0901.4172 Observations of type 1a supernovae are consistent with a static universe I have found several years ago that "observations of type 1a supernovae are consistent with a static universe" (so called "Einstein's universe"...

To clarify the issue a little more: The shft in the frequency of pulses (redshift) and the time between pulses (time dilation) are related to each other through the speed of the signal (c in this case). E.g. Doppler shift happens since some pulses come to us delayed , so the time rate in remote loca...

Einstein's theory of relativity is quite definite that if the universe is expanding then the observed duration of these measures will increase with redshift. [...] However the data are consistent with a static cosmology in a non-expanding universe. Even in a non-expanding universe (so called "...

Light is not a wave [...] And yet phase velocity (the one greater than c) refers to the phase of wave . Only the phase can move with speed greater than c since it is not a physical speed and it is only the "speed of an image in human brain" and this one can "move" at any speed. ...

"Most of us live in urban worlds where we think everything's totally well known," Beehler said. "It's a little bit of a reminder, just a wake up call, that we really need to know our world better so we can manage it better." But talking about knowing our world better and about a...

In the past month I read of light being sped 300 times beyond c in (cessium gas?) It is not the speed of light but only the phase speed of light . Some people keep dropping adjectives. Then non physicists who read this stuff get confused. The phase speed can be anything since it is only the speed o...

Hubble did not agree with the expansion idea and thought that the redshift was an "hitherto unknown principle of nature". The "unknown principle" turned out in 1985 to be the old principle of conservation of energy . It turned out that Einstein's original general relativity requ...

So, is Einstein God? or is he the only one who knows God's design? Even Newton was wrong. Could it not be that Einstein may be wrong. Einstein was a genius, no doubt, but a lot more is now known. Perhaps even Einstein would revise his view of the universe. Einstein was not infallible. Newton was ri...

here he goes again. man, I would love to see that non-symmetric thing math done correctly; that's really all you have to do to get people listening. makc, Einstein said already in 1950 that metric can't be symmetric (obvious to physicists, just common sense, not to mathematicians though) and they d...

Jim Jast - I find it hard to believe but you're beginning to make even me look at you as an odd kind of character. Why don't you post the math? It is not allowed in this forum to publish things that weren't published in a scientific journal yet. The proof that "Einstein's universe" (a sta...

'Reinventing Gravity: A Physicist Goes Beyond Einstein' - by John W. Moffat In 1950 Einstein said that metric tensor of spacetime must be non symmetric . Apparently he finally noticed the contradiction betwen symmetric metric tensor of spacetime and the principle of conservation of energy (symmetri...

Dark energy is that "repulsive" stuff to which you are referring. Neither "Dark energy" nor "repulsive gravitation" are ideas from science yet. They are hypothetical things proposed by laymen (if you read carefully the wikipedia's description that you quoted you might ...

And yet .. the mysterious 'replusive force' which some say is driving the universe apart, if it is a force, must be energy, and seems to be in the process of constant creation. Scientists don't believe in everything that people say, especially when they don't have any theory to explain the thing. T...

it is easy to say, photon was consumed, and the energy was used to move electron into higher orbit, and then forget about it; but if you keep thinking about it, where does photon go? A photon is a package of energy. If electron gets on "higher orbit" the photon is this energy that electro...

[space] is either flat or very close to it In Einstein's theory the flat space makes no sense. If space were flat the universe would have to be infinite, which seems a non physical solution. The space has to be curved to close the universe into a 3-sphere. One may estimate that the radius of curvat...

I fail to see how scientists can afford the luxury of taking anything for granted, and fail to see where the human race has the capability to prove the speed of light is constant, considering the vast distances light travels. I do understand according to my reading that it was Einstein who made the...

Maybe what gravity is shaping is only part of what exists in space like the meduim that carrys elcetro magnetic waves. People were looking for meduim that carrys elcetro magnetic waves (called ether) and it turned out that there is no such medium in nature. Einstein's theory of relativity came out ...

Hi makc, it is of cource true that speed of light has to be fixed because of relativity and we don't discuss that but only on what value it is fixed and why . The value we get experimentally, but why it has this particular value we have to guess. My guess is the sum of those 4 terms out of which the...

Hi Nereid, There are many quites about "two kinds of astronomers". Examples: http://imagiverse.org/interviews/janeluu/jane_luu_21_03_03.htm An Interview With... Jane Luu What do you do as an astronomer? There are two kinds of astronomers. There are observers and there are theorists. The th...

A while ago, acting under impression that this is an astronomy forum, I ceated a topic titled "Einsteinian reasons for Hubble redshift" hoping to get an answer from an astronomer, or at least someone undertanding problems with the metric tensor, to a question "why astronomers ignore E...

You must have overlooked the fact that out of 3 variables (speed of light, mas density, and pressure) we we don't know only the pressure so I just calculated only this one. I didn't calculate the speed of light since we know it. And the nature determines it possibly from the same relation that I use...
