Someone tried this silliness on another thread.
If time dilation says that the Earth can be both 6,000 years old and 4.5 billion years old at the same time, then length contraction means that New York and Paris can be both 5 miles and 5,000 miles apart at the same time.
I agree, 6.5 days and 6000 years is so bad it’s not even wrong! Now 15 billion, from one perspective, and 6.5+ from the opposite direction, well that tends to make sense, especially the way Fr. Schroeder explains it. But hen he is also a Torah scholar.
Time dilation isn't the only problem. It creates an enormously massive universe at the start of creation that no amount of inflation would be able to overcome. I sketch why this is true in #93. It creates a problem because objects inside of our Hubble Neighborhood with known time constants would have to appear to be slowing down, while the same objects in the distant universe would have to compensate by evolving even faster. It creates a time-energy uncertainty relation which makes the strong and weak nuclear forces to have approximately zero range -- atoms actually could not form. And it violates all of the following laws: energy conservation, conservation of linear momentum, conservation of angular momentum, and the Creationists favorite whipping boy: The Second Law of Thermodynamics. It means either the known spectral lines of distant starlight are all wrong -- and deliberately deceptively rearranged to be so -- or that distant stars have entirely different and unknown chemical compositions from atoms with electron structure that do not exist.
In fine and in sum: it turns God into a very evil being, whose sole purpose is to deceive people to their destruction. Now you bozos can say all the nasty things you want about science, because science will stand or fall on its own, but I will not have you insulting God, who is way too patient to defend himself against such slander.
