  1. So the gist of it is: Astronomers like their model and have a so-so relationship with statistics, confirmation bias and assumptions.

  2. No, the climate science guys doesn't have such high standards. 0,5 sigma is where it is at.

  3. Particle physics like 5 sigma. 3 standard deviations is: might be something here, lets investigate further.

  4. Remember that expansion of space a is an interpretation of observed redshift of very distant objects. It has not been measured directly.

  5.  @omsingharjit  - quick math indicate that a 10 km long cable should become about 1/1000 mm longer in a year, or 1/100mm longer in a decade. Easily measurable. Of course proponent of expanding universe will say it doesn't work that way, because reasons.

  6.  @omsingharjit  - yes Dark Magic works like that. Doesn't mean it exist though.

  7.  @omsingharjit  - So we have Big Bang (magic one-time event), Inflation (pure magic), Dark Energy (magic break all laws of physics), Dark Matter (not detectable) and expanding universe (but not here). I'm not very convinced for some reason...

  8.  @omsingharjit  - No, just one, then the rest follows like Domino bricks. I'm just not convinced the universe is currently expanding. If you take that assumption out of cosmology, then everything just falls apart.

  9.  @omsingharjit  - well, "strong evidence" = "some interpretations of observations and no direct measurements of actual expansion". Dark Matter is of course not directly related, but many of the models that say Dark Matter is required (and cannot be something else) is based on BB theory being true.

  10.  @omsingharjit  - as long as we haven't measured it directly or using techniques that doesn't rely on assumptions (for example parallax), then one must be very cognizant that it is an interpretation and not a fact. When you then take that interpretation and "wind it back" and end up with BB, Inflation and Dark Energy - to shoe-horn in some observations, then I would say: Maybe revisit your non-confirmed base interpretation, because if you got that wrong, everything that followed is also wrong.

  11. Astronomy has a long tradition of burning heretics.
