@SB: there is a big difference between science discovering more things to the WTBTS. Basically what you and the WTBTS do is have a fixed conclusion and make the data fit accordingly. What science does is collect fixed data and make the conclusion fit accordingly.
Hubble for example did collect data and was assuming the furthest things he could see were individual stars, based on that assumption, he calculated an age of the universe of 2Gy that was immediately falsified by the fact earth was already proven to be 3Gy old, so everyone knew something was wrong, they just didn’t know what. Only later on with better telescopes they found Hubble wasn’t looking at stars but at star clusters and that the standard candle and all the calculations they had made were wrong. If Hubble’s original observations were correct, they would’ve actually proven a created Universe as you describe.
In comparison, the WTBTS continues to hold that Jerusalem fell in 607BCE, despite the fact it didn’t and will continue to warp evidence to fit their calculation (the argument that the Babylonians were wrong, or that the Jews were captured but it was a different Nebuchadnezzar that came back and captured some heathens living in the area).
You for example, have a fixed assumption that the universe was created static, so any evidence is fitted to that argument. But you can’t or don’t want to explain and leave out evidence that counteracts your argument, such as redshift.
Redshift basically indicates that light has been stretched out since it was emitted. Very simplistically: light is both a particle and a wave and gets emitted and travels at a specific frequency, there is no mechanism that inherently slows down light. In a static Universe, a Universe that was created in a single unit as it currently shows up, light doesn’t shift, because it just travels along at the same frequency it was emitted. However the spectrum from far away stars has shifted (slowed down) significantly and we can see that happening equally in every direction. The only explanation is that both space and time between the stars and the observer has been stretched out while the particle/wave has been traveling.
The question is indeed for how long, in the last 100 years we’ve seen several adjustments, but they have confidence ratings, Hubble made a very rough calculation based on what he thought he could see. Had we not improved the observations at that time, the theory would be that the Universe was shrinking, which it can do if we were in a collapsing Universe so you won’t see a doubling of the time anymore, you’ll see minor adjustments in the lower significance digits.
So if your theory for a statically created Universe is true, you have to have matching evidence: no red shift, or an explanation for red shift (a curved Universe, but that has been disproven as well); an observable creator; no development (birth, growth, death) of stars and galaxies; a visible decrease or observable force that maintains or stabilizes entropy (that would preclude black holes since they are a visible source of entropy) Feel free to provide sources for all those observations, noting that at least one of those violates the laws of thermodynamics.
