Probably the same way we can know things like if you break a glass, it’s gonna stay broken. Or if you cut off a finger that it stays cut off.
Probably seen telomere damage from radiation or some such. Some sort of thing which doesn’t grow back naturally. So sans technology that will change our biology, we know some things are permanent.
Although like 20 years ago I could’ve used a tooth falling off as an example, but I first read about tooth regrowing studies in a science mag in the early 00’s and 20 years later we’re kinda there actually. The researchers hope to have it for general use by 2030. A tooth regrowing drug! Phase-1 human trials already concluded without adverse effects.
My dentist brought up what a bunch of bullshit that is at my last visit. He was saying that the drug causes teeth to regrow but we don’t know the side affects, or what else it will make grow. He made a good point that there are other places on the body that are somewhat predisposed go grow teeth given mutation. He mentioned this is why we sometimes see people grow teeth in their genital area.
Anyways, I’ll stick with bridges and whatnot personally.
The drug is basically ready to use. Just going over safety checks and they hope to have it out by 2030. So unless you plan on dying within the next few years, high chances it’s happening in your lifetime.
Which is good news for me, I lack 4 permanent teeth congenitally.
But I definitely know what you’re talking about, having heard about it on/off for literally 20 years. I think this team/research started in 2005.
I’m still waiting on the 3d printed spare organs. Read about those in the early 00’s as well. I think they’ve managed a rabbits heart already. A functional one.
they were able to print a rabbit-sized heart with a network of blood vessels that were capable of contracting like natural blood vessels. The printed heart had the correct anatomical structure and function compared to real hearts.
How can they say it’s permanent when it was only 6 months of data and the astronaut is still alive?

I’ve heard about the tooth regrowing so much I’m like “ehhh never happening in my lifetime, got it”. I hope I’m wrong!

Yeah, tumors love to grow teeth ;_;

Yeah that makes sense. Still seems like a bold statement but I can see where you’re coming from.
Time machines
Oh yeah. Good point!
