The more acceleration you experience the younger you stay. If you want to get older faster than others then either avoid acceleration or accelerate the others. | |

| Jul 24, 2019 at 15:33 | comment | added | Renan | @Hypnosifl Thank you. I would prefer it doesn't break causality, but I'm also open to a certain degree of handwavium. | |
| Jul 24, 2019 at 7:03 | comment | added | Hypnosifl | The wormhole solution suggested by Ash could work within what's theoretically allowed by Einstein's theory of general relativity, but it might lead to the possibility of causality violation, i.e. some person or object being able to influence its own past self (like my comment about a scenario where the traveling twin arrives on Earth shortly after his younger self left, and can then send a message his younger self will receive). Are you looking for a method that allows the traveling twin to age more while avoiding any possibility of causality violation, or do you not mind it? | |
| Jul 23, 2019 at 23:29 | comment | added | Renan | @Hypnosifl Suspended animation wouldn't work for me. What I'm thinking is person A met person B while person B was a child. The child Person B spent some time "somewhere". Some years passed (say 8 years), and Person A reencounters Person B, finding out Person B isn't a child anymore, but an elderly. Perhaps this is just too far from the plausibility realm? | |
| Jul 23, 2019 at 23:22 | comment | added | Hypnosifl | Are you ok with methods of slowing aging that don't depend on extreme physics effects, like suspended animation, or do you want it so the one on Earth really experiences less proper time in the physics sense? | |
| Jul 23, 2019 at 23:19 | comment | added | Renan | @Hypnosifl Yes, I'm thinking of the twin who stayed on Earth as the younger one. Is there any way it would be possible? | |

| Jul 23, 2019 at 18:42 | comment | added | Hypnosifl | If instead of being instantaneously transported, the other twin travels away from Earth at a significant fraction of the speed of light (as measured relative to the solar system) and then turns around and returns at a significant fraction of the speed of light, the twin who made the journey can be significantly younger than the twin who stayed on Earth when they reunited--this is the twin paradox. But I take it you specifically want it to be the twin who stayed on Earth who is younger when they reunite? | |

| Jul 23, 2019 at 18:04 | comment | added | Trevor | The twin that went somewhere isn't eating right, so they appear to have aged more when they get back. | |
