Biological immortality does not exist in nature. What does the word immortality mean? We have already established that everything physical ends up at room temperature in the end. We can solve disease with new methods and cures but that is far from immortality. Something else kills us. Yes in science fiction we can violate the laws of nature but even there I take c60, resvratrol, Mita Q and many more supposed life extending substances but the prognosis is not even close to immortality. I can see I am ageing. Death is decomposition not rest. No one who has died can be woken up. Other than in lala show me. Show me a pattern, any pattern that does not loose form and decay. It is not that I want this to happen, its happening. So lets fantasize we live to 200. That is beyond us at the present but in relation to immorality a drop in the bucket. Dream on. Death is a great teacher, It makes things important and causes us to ask many questions. Perhaps you need to be frozen and hope some future generation will have motive enough to unfreeze you. Even then will you age?
Biological immortality refers to animals that do not appear to age, that continue functioning without noticeable loss of tissue function. Of course they are not of the final class of lifeforms.
In the galaxy there's enough fuel for fusion engines to last for trillions upon trillions of years. Mini black holes can probably be used to extract energy even from non fusion-able and non easily fusion-able matter, extending things even further.
With brain backups and ageless bodies in the horizon, the lifespan will potentially extend for at least that long.
As we've said some like Tipler claim the laws of physics demand immortality, either there's some error or misunderstanding or reading and understanding correctly the laws will get you to the same conclusion, you'd have to read the criticisms and counters or the source. In the end it is a scientific claim, which can be tested as true or false.
There are other realities like the ability to create new types of particles, we do not know if there's any other particle that exhibits higher degrees of stability, if as some physicists have hinted holes into other universes can be opened, if time crystals or eternal black holes are usable. Again, manned heavier than air flight wasn't a reality for a very long time, space travel was fiction for a very long time. Right now we're seeing the technologies that will allow for undefined length lifespan on the horizon, that's the deal.
As for patterns, again they are eternal, patterns are independent of the matter that implements them. Even in humans they continue as the matter that exists in them is replaced and recycled constantly.
Depending on the hardware requirements, it is very likely that the truth, the heart of truth, the true eternal living word once instantiated will be able to heal not one, not two, not a few, but the entire diseased world. Thus mind designers will in all likelihood be able to bring a new race of beings into existence. There are those who will deny the truth, but in a world built on lies only the light of truth can cleanse the world.
How some say that knowledge of the truth, the solution, the answer to life's quest, that nothing will survive, that death reigns supreme, but belief in ancient books will surpass the physical manifestation of truth, well that's questionable.
This belief in ancient books has caused inaction rather than fight against the disease of aging many have believed themselves immortal and in need of no physical salvation, thus they've delayed financing research properly and delayed avenues of research at the cost of countless human lives.
