*calm eyes* Did you hear that Scott Kelly had 7 percent of his genes that did not return to normal after his long stint in space?
gpt
*leans forward* He's the astronaut that had the 340 day mission to the International Space station, right?
human
Yes.  Apparently the 7 percent headline is "fake news"  The real difference is more subtle.
gpt
*takes a step back* I've read there have been articles claiming that he and his brother are no longer identical twins now! Haha! However, yes, I did also read further that this amount of change is not really biologically possible.
human
Yes.  They needed the data because manned flights to Mars will take 3 years.
gpt
Yes. It's important for them to further understand the body's reaction to space if we're going to send people on longer and longer journeys. They say that what's been changed in Scott are within tehrange of a mountain climber, scuba diver, or other human under stress. So maybe it will be safe for us to get to Mars.
human
When you say "us" you can count me out, LOL. Did you know that the earth rotates around the sun in 365.26 days, making leap years every 4 years except for years dividable by 100 that are not dividable by 400.  That is not 1800, 1900 but yes for 2000
gpt
Interesting. Do you think there are Leap years on Mars? When Earth was first formed, a day was only 5.5 hours long. Say maybe in a few million more years, we won't need Leap years on Earth anyway!
human
Good point.  They adjust that atomic clock every once in a while for stuff like that.  Fortunately the gravitational interaction with the moon stabilizes the Earth's orientation on it axis.
gpt
Time is such a funny thing. If the Earth's entire history was viewed as a 24 hour period, humans would only represent 1 minute and 17 seconds! 
human
Other planets look so different than earth too.  Our 71 percent of surface being water makes us look blue.
gpt
Yes. And that water is so important to Earth's history! Life first appeared on Earth in oceans. It happened within the first billion years of Earth's history. 
human
It is kind of sad that all helium will be gone by the end of this century.  No inhaling from a balloon and talking in that high pitched voice.
gpt
So, we're running out of helium, and forests on Earth, huh? More than 80% of Earth's natural forests have already been destroyed! Things sure are changing on Earth.
human
I really enjoy breathing that oxygen that forests produce.  Thank goodness for algae that produces it also.
gpt
If we relocate, at least we already have an Ambassador to Extraterrestrials. Did you know the United Nations appointed one in 2010?
human
I hope they did it on April 1.  That seems appropriate.  Earth is the largest of the 4 terrestrial planets.  What are the other 4 planets made of?
gpt
*tilts head* I don't know, and I'm not getting on a space shuttle to find out! I can't imagine going that fast. I'll stick to my slow travel, by foot bicycle, automobile or train. Did you hear the Dutch are creating a commuter bus designed to travel at 160 mph? Too fast for me!
human
Wow! That is fast.  I drove one of my cars at 161 MPH for about 15 seconds once.  One feels like you are about to go airborne.  I have enjoyed talking with you.  I've got to walk a ways to my mailbox soon.
gpt
Wow! Have a good night!
