There are questions on both the distance...and time calculations made...i'd guess those are both kinda critical to the results...
Yes, and this has been talked about long before this. Without accurate verifiable data, any theory could fit the bad data.
In science, data that contradicts basic laws can not be trusted.
An single object can not be in two places at the same time.
Or, two injects that are in separate locations can not share the same mass.
No object can have zero mass.
The behavior of sub-atomic particles has not been verified. When and if that can be done is not yet known. One might suppose that someday that might be done. But past success in finding answers does not guarantee the possibility of rational anders to the remaining questions in atomic physics. How can one be sure that a question is a valid question?
What is the size of space?
What is the mass of emptiness?
What is the least non-zero quality of anything we measure?
How precisely can time be divided into units? Is the a limit?
What is beyond the edge of the Universe?
What was there before the the Big Bang?
The above questions may not be valid questions. In may not be possible to prove any or all of them invalid. Much, if not all, of our understanding is by observation.
Unless you include dreams.
One writer woke up in the night a wrote a profound idea on his notepad. He went back to sleep and forgot about it. Until later he saw it and read:
"The whole Universe reeks of the smell of kerosene."
