As long as it is not pseudo science its ok. Otherwise it become annoying and boring.

For 3500 years the de bunk said the earth was centre of the universe. Thirty Five Hundred Years. Thirty Five Hundred Years. Thirty Five Hundred Years. That's a lot of bunking. That means a lot of bright people were bunked. 'B' is a bunky letter .. begins the two words "Big" and 'Bang'. How much pseudo science do we have when to support BB someone comes along and says, 'Inflation .. all the gaps are filled by inflation'. And all the bunked brains said "Inflation! Of course!"

Chris, Do you consider anti-gravity different from reverse gravity? If not, some of the best minds in the world are working with anti-gravity. Mog uses it.Chris Peterson wrote:... and there's no such thing as "reverse gravity".

There's not the slightest shred of evidence that there's such a thing as either anti-gravity or reverse gravity.aristarchusinexile wrote:Chris, Do you consider anti-gravity different from reverse gravity? If not, some of the best minds in the world are working with anti-gravity.
No, it's not, and you should learn what "pseudoscience" means before you start throwing around a word you don't understand. The BBT may be wrong. Inflation may be wrong. But neither remotely falls into the category of pseudoscience. These are solid scientific theories- accepted as such even by the small number of scientists who prefer alternate theories. Inflation, for instance, makes a number of predictions- some of which are supportive of the theory (the structure of the CMB, for instance), and others which could be used to reasonably prove it wrong.aristarchusinexile wrote:How much pseudo science do we have when to support BB someone comes along and says, 'Inflation .. all the gaps are filled by inflation'.

Abstract: The concept of expanding space has come under fire recently as being inadequate and even misleading in describing the motion of test particles in the universe. Previous investigations have suffered from a number of shortcomings, which we seek to correct. We study the motion of test particles in the universe in detail, solving the geodesic equations of General Relativity for a number of cosmological models. In particular, we use analytic methods to examine whether particles removed from the Hubble flow asymptotically rejoin the Hubble flow, a topic that has caused confusion because of differing definitions and invalid reasoning. We conclude that particles in eternally expanding but otherwise arbitrary universes do not in general rejoin the Hubble flow.
Starting from the assumption that general relativity might be an emergent phenomenon showing up at low-energies from an underlying microscopic structure, we re-analyze the stability of a static closed Universe filled with radiation. In this scenario, it is sensible to consider the effective general-relativistic configuration as in a thermal contact with an "environment" (the role of environment can be played, for example, by the higher-dimensional bulk or by the trans-Planckian degrees of freedom). We calculate the free energy at a fixed temperature of this radiation-filled static configuration. Then, by looking at the free energy we show that the static Einstein configuration is stable under the stated condition.
Analysis of type 1a supernovae observations out to a redshift of $z$=1.6 shows that there is good agreement between the light-curve widths and $(1+z)$ which is usually interpreted as a strong support for time dilation due to an expanding universe. This paper argues that a strong case can be made for a static universe where the supernovae light-curve-width dependence on redshift is due to selection effects. The analysis is based on the principle that it is the total energy (the fluence) and not the peak magnitude that is the best `standard candle' for type 1a supernovae. A simple model using a static cosmology provides an excellent prediction for the dependence of light curve width on redshift and the luminosity-width relationship for nearby supernovae. The width dependence arises from the assumption of constant absolute magnitude resulting in strong selection of lower luminosity supernovae at higher redshifts due to the use of an incorrect distance modulus. Using a static cosmology, curvature-cosmology, and without fitting any parameters the analysis shows that the total energy is independent of redshift and provides a Hubble constant of $63.1\pm2.5$ kms$^{-1}$ Mpc$^{-1}$. There is no indication of any deviation at large redshifts that has been ascribed to the occurrence of dark energy.

By your definition, Chris, atomic theory is pseudo-science (from your own referal to Wiki:"The word empirical denotes information gained by means of observation, experience, or experiment.[1] A central concept in science and the scientific method is that all evidence must be empirical, or empirically based, that is, dependent on evidence or consequences that are observable by the senses."

No, science formulates theory based on observation, and when contrary evidence comes in, either replaces or modifies the theory, to better fit with actual observation. That's why we have both inflation and dark matter; they help to explain our observations better than earlier theories.aristarchusinexile wrote:And your idea of real science is to forumulate a theory on observation, then when contrary evidence comes in, to create fudge factors (inflation, Dark Matter) to fill in the holes created by the new evidence.

No. The observations inflation and dark matter attempt to explain were not the observations the Bang was founded on. Inflation and DM attempt to explain later observations. A new theory would have been difficult to formulate, and fuge is nice and sweet, goes down easy if you take it in small bites.Chris Peterson wrote:No, science formulates theory based on observation, and when contrary evidence comes in, either replaces or modifies the theory, to better fit with actual observation.

Indeed, the form of science is very nice.

I didn't call MOG pseudoscience. Certainly, there are forms of MOG that are, but not all. The more reputable work with MOG theories I'd describe as weak science: the theories don't do a better job than existing theory in explaining observations, and have a harder time explaining much of what we do observe. So I don't find them compelling or necessary, and have little interest in discussing them. Weak science is totally different from pseudoscience, however.MOG certainly isn't pseudo-science, yet you fail to discuss it.

Exactly what Chris said.aristarchusinexile wrote:The observations inflation and dark matter attempt to explain were not the observations the Bang was founded on. Inflation and DM attempt to explain later observations.
That's exactly what I said. Theories in areas that are still under study are fluid. Science is an iterative process of improving the quality of knowledge. Theories often start out rough (the BBT, for instance, postulated nothing more than expansion from a point of origin- crude by current understanding). Theories suggest observations, those observations are then used to refine the theories- as a rule, to make them more accurate. Occasionally major theories are discarded, but that is very rare. Most often, they are simply revised.aristarchusinexile wrote:No. The observations inflation and dark matter attempt to explain were not the observations the Bang was founded on.

Not exactly. Chris thinks DM, DE and Inflation support the original observations which led to the BB theory, in reality the later observations should have caused the bb theory to have been discarded because the later observations necessitated creative imaginings (inflation, DM and DE). Where is the empirical method in creative imaginings? My theory needs only anti-gravity and Pascual Jordan to explain the processes, and anti-gravity is bound to be as real as anti-matter.bystander wrote:Chris Peterson wrote:... science formulates theory based on observation, and when contrary evidence comes in, either replaces or modifies the theory, to better fit with actual observation.

I find it difficult to accept that you have read much on MOG, especially Moffat's latest. I find it easy to accept that you have found a comfortable place for your own belief system, and you choose to remain in it. This is common to mankind, but not very scientific.Chris wrote: I don't find them (MOG) compelling or necessary, and have little interest in discussing them.

You mean like anti-gravity bubbles?aristarchusinexile wrote:Where is the empirical method in creative imaginings?
I don't know where you're getting this. The "original observations" that led to the BB theory were nothing more than than the observation that there was a relationship between redshift and distance. That led to a simple BB theory. Since then, richer and better observations of many other things have led to a richer and better BB theory. All science requires "creative imaginings", since that is fundamental to the development of theories from observations.aristarchusinexile wrote:Not exactly.

That makes as much sense as saying that your theory needs only pigs with wings. Seriously, there is absolutely no difference between the two assertions. In fact, what your "theory" needs is a theory.My theory needs only anti-gravity and Pascual Jordan to explain the processes, and anti-gravity is bound to be as real as anti-matter.
