If it was possible to replace somebody’s mind (brain) in the same manner as having a heart transplant, how would that kiind of technology really work even if it existed? That means disconnecting the old brain from all the nerves, blood vessels and spinal cord and implanting a new brain into them without losing their core functions keeping them in-tact. Now the doctor has the task on reconnecting all the nerves, blood vessels and the spinal cord, but the question remains: would it still be them or someone else? Would they still have all their senses? Would they regain their basic functions? Are they abled bodied or now a vegetable? Would they possess someone else’s toughts? Does that mean taking immunosuppression drugs for the rest of their life?

Can artificial hearts unlock immortality?

Can artificial hearts unlock immortality? - Lemmy.World

The thing is that, can artificial hearts really make somebody immortal or will they still pass away even though their heart is replaced with an artificial one? However, that only affects the heart while the brain will continue to “decline” as people get older. The technology and science behind the invention of artificial hearts exists but does that alone “cheat death” or just temporaily extend an individual’s life span rather than making them “live forever”? Can artificial hearts really resurrect humans?

Teleportation is considered “science fiction” for the most part since no one has managed to invent such technology allowing that to be possible. Like being able to “fast travel” from one place to another without being intercepted or inspected by official parties. However is the concept of “warping” beyond known science? As instead of relying on vehicles, aircraft or vessels for modes of transportation (due to them being prone to unexpected events, delays, damage or wear & tear) like how air space is closed in UAE due to what’s occurring in Iran: would teleportation alone really solve this since it is instant travel without having to consume time such as waiting for the next flight for instance. Even if teleportation were to be standard: would that deem all airplanes, trains, boats, ridesharing apps or car ownership obsolete since everyone can just warp from point A to B within a click of a finger (as in that level of convenience) but is today’s technology possible on being able to achieve such a feat on temporarily breaking human atoms & being restored in another location?

I’ve noticed cheap green acrylic paints tend to degrade quicker than other colors - what could cause that?

Maybe it’s just been the “apple barrel” cheap brand, but it seems that the lighter green varieties turn into a completely thin green liquid after a few years that smells vaguely like an alcohol/“chemical-ly.” It’s specifically the greens that do this, so I’m wondering if there’s something in the green pigment that reacts with the binder after time. Most other cheap acrylics tend to dry out - reds more so. Is there some sort of slow chemical reaction happening with the greens instead?

If Peaceful Aliens beamed down. Wouldn't we pose as much problem as them being out immunities and diseases are different from them? And vice versa? So we could accidentally kill one?

Posting here first before no stupid questions. Have or has anyone developed synthetic oil? That does not rely on sucking the earth dry? And we can pretty much get rid of the oil prob?

If someone today made an Iron Man suit with all weapons and everything how much would something like that cost today? Also if not be able to be made what are some limits holding us back?

So in the long run, all that we have built will build and thought of building will pretty much be worthless since we have would cease to exist?
