      +Atzin I don’t know, do you think spending 900 Million dollars to send someone to do nothing for a year is not a waste? If he was on a certain mission and they asked him to take blood samples while he is out there it wouldn’t be a waste.
      But sending someone to the space just to do some sampling and absolutely nothing else is just Stupid and waste of money and people’s time.

    But race is a social construct, so why does the color of the skin matter? :p

      There is some genetic differences between races.

    3:40 What is going on here? I’m sure that animation is meant to depict a chromosome with telomeres on the tips, but that has almost no resemblance to the structure of a chromosome. It bears closer resemblance to a double helix of DNA.

      Will Peer you are in fact correct, does not look like chromosomes at all

    I don’t have a twin brother but hey, I can pretend. I’m also willing to relocate to space for the new job if necessary. Will not pay moving fees however.

      in reality earth is flat and stationary, outer space does not exist, there is a dome/firmament above us. go to my playlist and watch the videos and learn about flat earth, if you really research flat earth then you gonna become a flat earther, I promise you. ——————————- don’t try to debate with me because you gonna lose, I debated with a lot of globe believers and none of them could prove the earth is a spinning ball, there is no curvature……

    Nasa seem very adept at PhotoShop & CGI. Glad to see all the taxpayer’s dollars aren’t going to waste.

    Eternity is to long to get this wrong. Accept Jesus Christ today, we are not promised a tomorrow. It is a free gift, take it. Do not get microchipped and do yourselves a favour and watch these channels, ThePottersClay, Shaking My Head Productions and Richiefromboston.

    Now lets examine the difference between a flat earther and a sphere earther.

    Probably only happened in Germany, in mid 1940s, relative to the astronaut activity or capabilities or terminology of the time. Just saying.

    Wait, you are telling me the astronaut on earth didn’t follow the same diet as his brother? What a letdown, then what is the point.
