I can’t think of any version of immortality that wouldn’t eventually be a living hell.

Being immortal doesn’t necessarily mean you don’t feel discomfort or pain. Even if you do have a version that doesn’t feel pain or discomfort, you could still be trapped, unable to move, in complete darkness, for all eternity.

Step 3. Hope that if people are given the ability that they can live without consuming anything

If human immortality is widespread to a larger population, its even worse. People stop dying, but resources don’t increase. Some versions of immortality also mean humanity becomes sterile. So the population never decreases because people alive today will still exist, but never another new generation.

Step 4. Did i immortal so well now we are all going to have to figure out how to inhabit the interior of the sun.

An immortal “human inhabiting the sun” will mean a human the enters the outer corona, but never having their flesh burn because of the magic immortality. However all your clothes would be burned off long ago. So it would be a bunch of naked immortal humans slowly descending toward the core of the sun eventually being wrapped around the dense pure-neutron core where the affects of gravity would be 100 billion times Earth gravity. You’d stick to it unable to move a single muscle. Matter would be pressing again you all over your body at that same strength. Eventually pure neutrons would encase you inside the core of the star. you’d be stuck in the solid heart of a star for all of eternity.

If we had a larger sun, you might have had the chance to escape when the sun goes supernova and be cast out into the galaxy, but you’ve got bad luck to be stuck in our solar system and our sun isn’t big enough to explode as supernova. Instead, our sun will eventually become a white dwarf, a small star slowing bleeding its remaining heat out into space. This process will take literally trillions of years. Eventually when that heat is gone our sun will be a black dwarf. We have no idea what happens after black dwarf because none exist because the universe isn’t old enough yet! Our universe has only been around for 13.8 billion years.

So I hope you enjoy your immortality stuck inside the heart of a cooling star unable to move a muscle with the rest of naked humanity mixed in with you.

I’ll be keep my mortality knowing I’ll be happily gone in less than 50 years, thanks.
