Is it Possible to Flash Freeze the Human Brain and Send it into Space?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of flash freezing a human brain after death and sending it into space, exploring the implications of temperature and decay in the vacuum of space.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant proposes the idea of flash freezing a brain post-mortem and sending it into space, questioning the potential for future alien civilizations to restore it.
  • Another participant inquires about the temperature in space, suggesting that the low temperature might prevent melting.
  • A subsequent post reiterates the temperature of space as approximately 2.7K and questions whether this temperature is sufficient to prevent decay.
  • Another participant mentions sublimation as a concern at such low temperatures, indicating that it may pose a risk to the preservation of the brain.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the effects of space conditions on the brain, with multiple viewpoints on the implications of temperature and decay, indicating that the discussion remains unresolved.

Contextual Notes

Participants have not fully explored the assumptions regarding the preservation of biological material in space, nor have they reached a consensus on the effects of sublimation versus decay.

I've seen online that you can get a handful of your ashes sent into space for a hefty fee1 and it got me thinking... Would it be possible when dead to flash freeze the brain and send it up into space in a radiation proof container and just allow it to travel through space like the voyagers do?

Or would it eventually melt and decay ect? The reason I ask is because when you're dead, your dead as far as we know so I thought what is there to lose if someone wanted to send their brain into space and who knows, in a billion years an alien race might find it, defrost it without damaging it and somehow restore it or transfer it's memories onto a computer or something.

Obviously this seems somewhat farfetched and probably impossible but I thought I was ask why this would or wouldn't be possible. The biggest concern is the brain defrosting over time.

What is the temperature in space?

~2.7K so I'm guessing it won't melt but is 2.7K cold enough so that decay won't occur?

Yes, what you have to worry about is sublimation.
