My concern with it is the assumption that the ratio has always been the same as it is today. If, the ratio 10,000 years ago was half of what it is today then things that died 10,000 years ago would appear to have died 20,000 years ago.
Conversely it the ratio was double then it would appear to have died only 5,000 years ago.
There is not a single proof for the theory that time was faster or slower in the past, that the ratio has changed. Facts please.
What is true is that the time runs slower when you come close to light speed. Or in gravity fields. Measurable with the satelites that rotates around the earth. Here the time goes a bit slower, speaking of a milifraction of a milisecond. But there is no negative gravity. And so no way to speed up life on earth in such a dramatic manner to win thousands of years. There would be the theorethical way to slow it down in such a dramatic manner to win thousands of years. But the gravity/acceleration would kill all life then.
Nonlinear time, absolute to the universe, would not work. The whole physics would fall apart, chemical processes stop working. Because all is bound to energy, mass and time, it is bound to E=Mc². And this means the time has to be constant, linear. Because else you would change the light speed constant, and the formula quits working.
Ah, who cares about a formula you mean? Well, what happens to an atom that looses constantly energy? It will fall apart into radiation. What happens to an atom that gets constantly energy? It will heaten up. Up to the point where it becomes a plasma. Neither radiation nor plasma are really healthy for life. But this will happen when E becomes unequal Mass and time².
Nope, just letting things run faster or slower doesn't work without smashing the Universe into pieces.
Let's just for fun think about this case from another angle that could workaround the E=Mc² problem. Let faster or slower time happen relative to the universe. The whole universe becomes faster or slower, not just the content. So the life would also live faster or slower, dependand to the whole system. Then in the end they would have always lived the same time, no matter if they were in the faster episode or in the slower. Because it happened relative to the whole system. Which means it happens for the viewer linear, not nonlinear. There wouldn't be a difference
Nope, there is no nonlinear time. No matter from which angle you look. Time has to be linear. Else the Universe would disappear, it would break the causality.
