It isn't a remnant of the event we call the Big Bang, as has been claimed by other respected astronomers?

George F. Smoot of Lawrence Berkeley National Laboratory in California and John C. Mather of NASA’s Goddard Space Flight Center in Maryland were awarded science’s highest honor for depicting the universe as it was 380,000 years after its birth in the Big Bang.
Their feat, precisely measuring the faint light that revealed the seeds of today’s galaxies and superclusters, affirmed the big-bang theory to even the most stubborn skeptics.
Smoot and Mather won the 2006 Nobel physics prize for their role as chief architects of a NASA satellite observatory named COBE, for Cosmic Background Explorer. Launched in 1989, the spacecraft measured feeble remnants of light that originated early in the history of the universe, about 380,000 years after the big bang. Until then the universe was opaque to light, making it impossible to directly observe anything older.
I agree with you Joe, these 'respected astronomers' have careers to protect. It's the non-professionals who need to move this question along. But how can alternative views be seen in print if the peer reviewers want to protect the status quo?Joe:"It isn't a remnant of the event we call the Big Bang, as has been claimed by other respected astronomers (?)"

Is that a bad thing?cigarshaped wrote:And so it goes on, theorists introduce modifications to fit the observations.
Well Davep you would hope that the theory predicts the observations and does not need endless patches to make it fit them. You might also hope that each new challenge would awaken the question: "Is our original hypothesis wrong?".cigarshaped wrote:

Why? If a theory mostly works but is also involved in an iterative process of refinement, what's the problem?cigarshaped wrote:Well Davep you would hope that the theory predicts the observations and does not need endless patches to make it fit them.davep wrote:Is that a bad thing?

Interesting. Where can I find more?cigarshaped wrote:What is a lot worse is when contradictory evidence is not only omitted but blatently edited out. This is what Halton Arp claims happened to images of quasars joined to galaxies via gas 'jets'. Our 'respected astronomers' allowed these images to be cropped or edited to avoid questioning the sacred red-shift assumption.
Slightly off the BB but I always felt accretion an oversimplification of what we actually find.Are accretion discs that "off the wall"? Even I can grasp the concept. They have even been photographed. Admittedly the jets are problematical but I often read about magnetic fields and plasma being big players in the mechanics of the solar system and beyond. Am I wrong? Perhaps I need to read a bit more of what plasma physics is about.
Assuming that you can explain a 'gravitational source', 'large cloud of material', 'accretion shock' etc this sounds like it was invented on a sandy beach holiday compared to what we know about plasma. It also relies on the idea that each object in space is disconnected, apart from these magical 'clouds of material'.An accretion disk is a structure formed by material falling into a gravitational source. Conservation of angular momentum requires that, as a large cloud of material collapses inward, any small rotation it may have will increase. Centripetal force causes the rotating cloud to collapse into a disc, and tidal effects will tend to align this disc's rotation with the rotation of the gravitational source in the middle. Viscosity within the disc generates heat and saps orbital momentum, causing material in the disc to spiral inward until it impacts in an accretion shock on the central body if the body is a star, or slips toward the accretion shock if the central body is a black hole.
...active galactic nuclei, protoplanetary discs, and gamma ray bursts are only a few phenomena in which they are thought to occur. These discs very often give rise to jets coming out of the axis of rotation of the disc. The mechanism that produces these jets is not understood.
that's because it isn't a mechanism!The mechanism that produces these jets is not understood.
Am I to take it that you've got a hypothesis that you wish to promote? That's nice. But it doesn't really answer the questions I asked does it?cigarshaped wrote:I've just posted something similar to Spodzone so here's my bit for today:
There's nothing 'off the wall', just the opposite. They are very down to earth mechanically minded ideas. You could probably make a very nice CGI movie to demonstrate it. It worries me that gravity is the only force seen to be at work. Newton saw the apple and wrote his laws based on the earthly physics he could see. We've known about electricity for 200 years. It's 10^27 times more powerful yet still not recognised in space.Are accretion discs that "off the wall"? Even I can grasp the concept. They have even been photographed.
Boy! Are the jets a problem for the mechanical system. But I must warn you about the second bit "magnetic fields and plasma being big players in the mechanics of the solar system". You cannot segregate a magnetic field and plasma from electric current. All 3 must co-exist that's nature. If you remove electric current, as the astrophysicists seem to do, then you are changing the laws of nature!Admittedly the jets are problematical but I often read about magnetic fields and plasma being big players in the mechanics of the solar system and beyond. Am I wrong?
I guess a certain amount of frustration must creep into the Electric Universe arguments when so much effort seems to be spent on keeping controversial ideas out of the public/ academic arena. The impression that academics give is for closed rather than open minds; careers and funding, maintaining the 'belief' system, etc. As with Wikipedia, if its not in print it can't be true?..wrong because they know nothing of plasma physics. It is not suggested that they are mistaken, they are snearingly dismissed.
