what is your dignosis

[suntrack2]

Think, suppose a man went for a space journey for almost 10 years, so this is the vast period for that man and when he reaches to earth later, what kind of changes we can see.

a. about memory of that man
b. about overall health of that man
c. about experiences of space

2. suppose that man never kept any contact with the earth, and only came in contact after the journey of ten years, so what immidiate changes can be seen in such case. 3. suppose he has lost the "speaking ability of the earth languages", and giving irrelevant signs of speaking by moving fingures in the air, so how we could understand that man.
4. will there be a great pshychological impact can be seen in such case.!

This is purely a time pass topic, not serious one.

Diabetes, and a broken knee
I wear glasses, cause I can hardly see
I'm just a medical mess with only 6 weeks left."

My diagnosis is actually more complicated, but not as lethal.

I would be curious as to how a lonely astronaut would leave without VD, but come back afflicted.

...on second thought, I think I'd rather not know.

Supposing the astronaut was alone, as I gather from your hypothetical, and had no outside contact, I think he'd come back quite insane. I won't bother with the bone density/muscle atrophy issues because we'll assume that if they have the tech for a 10-year voyage, they'll have addressed those issues already.

I think he'd be dissapointed to find that in the 10 years he was gone, landing gear became obsolete therefore the target airstrip had been dismantled. :)

3. suppose he has lost the "speaking ability of the earth languages", and giving irrelevant signs of speaking by moving fingures in the air, so how we could understand that man.

Just being alone for ten years would not make you lose the ability to speak. There are many people who go for long periods without speaking their native language, and they don't forget it. They may have some problems remembering words for the first couple of days. I personally can do OK with languages that I haven't spoken for more than a decade, though I get very rusty.

Jens, thanks for the reply, in case of that fellow got a result into a stressful journey almost for ten years in the space which result into a cronic brain desease and suffer from dementia, so then! I think in dementia man can think irrelevant and even speak irrelevant, even beyond our imagination.

As one of my least favorite long-time customers suffers dementia, I'll whole-heartedly agree. Her irrelevant but passionate rants against this or that can be mind boggling. Fortunaly, because she's easily confused, it's easy to steer the conversation.

does the OP say anything about velocity?


if the guy was moving at .0000001c then the earth wouldn't have changed much at all.

[suntrack2]

laboratory dignosis report: nil, negative.
symptoms occured: nil
results showing no massive changes in the person.
functioning of the man : within the normal limits.
no headache,stress,fast heart beating found.

will it be a true report.

[Fazor]

It could be. The report could also say "Subject found with large void in head from high-velocity space debris impact".

If you are questioning medical repercussions from a 10 year space flight in a vehicle similar to the current shuttles/capsules, then there are some very negative effects of extended weightlessness that have been documented by both NASA and Soviet missions. I'm sure you can look them up, but I think muscle atrophy and bone-density loss are among them, aswell as extended exposure to radiation.

But one would assume that if some agency was embarking on a 10-year mission, they would address the known issues before sending the traveler along his way. Psychologically, it would be interesting to see how one would respond to being alone, or in close quarters with a small group of others, for that time.

None of this considers relativistic effects of traveling near the speed of light, as I didn't gather that as part of your "what-if" scenario.
