Everything is relevant to science.
Dad is simply pointing out things that aren't relevant to current beliefs about science.
Since we don't even know what time is how can we possibly say how it works at the edge of the universe? It's like not defining "consciousness" and then studying life. Results are always a product of the assumptions that led to them.
Science is a methodology and a tool of how we acquired propose to explain a given phenomena - a proposed knowledge - and then test them if they are true and false.
The knowledge don’t come from god(s), angels, spirits, fairies or extraterrestrial aliens.
So everything are based on how we understand the world around us...and that’s including “time”. We use the time that we know of, in units that we understand, and we calibrate them in accordance with the given phenomena.
Like I said, they (natural and physical sciences) were written for our understanding, and if possible find applications to make use of we know and understand.
The scientific models (I am referring to the tested and accepted scientific theories, and not proposed theories hypotheses) weren’t written for gods or aliens from other planets to understand.
I think it would be very stupid to measure distance and time that have no consistency because dad think we should use time based on the given locality of the investigated phenomena.
Say for instance, let’s say we find the star system in Andromeda Galaxy, and that star (let’s call it Z) has only 5 planets. Then let’s say we choose that the planet in the middle (3rd planet), and called it C.
Now let’s planet C take 72 hours for this rotate to do one cycle. And it take this 600 of C’s day to one orbit around the star Z. That’s great to know about the planet’s information, but would we use these information to calculate a new light-year and measure the distance between planet C and Earth, in new altered light-year.
And for every planet, star and galaxy discovered we would have to alter times, everytime, to get new and different speed of light, which would give different distance light-year.
It would be utter chaos, to change speed of light and light-year every time we find new planets, stars or galaxies.
And it isn’t just modern astronomy that dad has. He has problem with measuring times on geological evidence, on archaeological evidence and paleontological evidence.
He claimed that the law of physics was different before Genesis Flood, and claimed that scientists cannot use radiometric dating methods or other methods to measure any objects, prior to Genesis Flood, which btw there are no flood occurred 4400 years ago.
Dad really think and believe that the Earth and life exist, is only about 6000 years old, and that dinosaurs were around living between Adam and Noah, all died out by the Flood; he believed that the K-T (or K-Pg, Cretaceous-Paleogene) extinction event occurred with the flood 4400 years ago, not 65 million years ago.
If what dad say and believe were true, why don’t paleontologists find human remains or fossils dated to the same time as dinosaur fossils?
If what say is all true, then why cannot provide a single evidence to everything that he claim, including evidence that different law of physics, evidence for the Flood itself, evidence that humans dinosaurs lived in the same time prior to the Flood.
He claimed that radiometric dating are not possible, and yet we have evidence that Jericho (Tell el-Sultan, 11,600 years old), Damascus and other Neolithic towns dated and existing before the supposed creation of Adam 6000 years ago.
Using carbon-14 dating is not too much problem dating stuff less than 10,000 years old (eg Neolithic periods, Bronze Age, Iron Age, etc), unless you find objects that over 50,000 years old. That is due C-14 would be have been completely depleted in most objects by 55-60,000 years. It is why geologists and paleontologists would use different radioactive isotopes to measure rocks, minerals or fossils, eg specific isotopes of potassium, lead, argon, uranium, etc.
Uranium dating method can date the oldest minerals and rocks on Earth. The only place you can find rocks or minerals dated to the Hadean eon (the oldest eon in the Precambrian) are only in Western Australia, northeast Canada, and parts of Africa.
But we have found even object older than our Solar System, like Murchison Meteorite, which crashed near the town, Murchison, Victoria, Australia, in 1969. Not only did scientists find organic matters, like amino acids in the meteorite, but that the the mineral silicon carbide is dated to about 7 billion years old.
You cannot use C-14 to date something as old as these minerals in the meteorite, but you can use uranium-238, which have half-life of 4.5 billion-year.
If dad is going to make all sorts claims that are contrary of evidence that have already been detected, measured and tested, then dad must provide counter-evidence to support his claims...which to date, he hasn’t done.
All he has done is try to shift the burden of proof to prove him wrong. That’s not how science work.
When a person bring a new hypothesis as alternative to the existing accepted model (scientific theory), then he or she needs to provide all the evidence and data he or she has collected for examination and analysis by the peers. Without evidence and data, peers can reject the model as being unfalsifiable.
All dad ever done was being evasive, when it comes to supporting his claim with evidence.
Dad doesn’t even need to be the one to supply the evidence and data, he can cite peer-reviewed works that support his claim...which he also haven’t done.
So basically all he has done, is make his numerous claims without ever backing them up. From my experiences conversing with him here, his words cannot be trusted.
