We need to change the human DNA to travel to the stars-thoughts of space exploration of long-term

Not long ago, I was talking to my friend a conspiracy theorist, who is completely in the entire concept of UFOs and aliens from outer space. In fact he travels to Roswell once a year for their annual convention and the anniversary of the Roswell incident. He is a fun person to speak, until I need to talk with him for too long, because really what comes in.

However, the other day over coffee, which I have asked what happens if there are actually aliens from Roswell aliens at all, if they are genetically created by man for long-term space travel? What happens if there are or share our DNA and were created by us in the future and sent back to times gone by. And what if they were doing well their travel time, but unfortunately falls into their ship when it entered the area of radar field who interrupted their system or antigravity propulsion system, causing them to crash to the ground in Roswell?

After I asked this question because, as you probably realize that I am a reader of science fiction, smiled and leaned forward to hear what he had to say. Oh, that he was livid, sees this meeting as a great alien conspiracy, almost as if it is a religion of some kind, is totally bizarre. Still, the question that I had put forth worth thinking about. Not from a theoretical point of view of the conspiracy, but rather from a science fiction point of view of what we might have to do with the future, if we want to travel to the stars.

Humans have too many bones for zero gravity long-term space flight, I really do not handle radiation very well and there is a lot of radiation in space. Humans also eat too much for long-term space flight. However if we could resolve those problems through genetic engineering could send people or genetically species, which are almost like humans to do exploration for us.

Perhaps NASA should think here (hint: they are already), and maybe we can use whatever we learn to human DNA modified to use less energy here on Earth, to eat less and get rid of some of the things that we don't need help. For example, we don't need a tailbone and our feet enough fun watching whereas we wear shoes. There are a lot of things on the human body that are not exactly what we need to survive here on this planet, and these things can be changed, that would make our lives easier and more adaptable.

It would also make sense to do this for those who want to live in space colonies, so they can survive for long periods of time without those conditions that are here on Earth. We should study this, even if we human beings are not genetically modified in the future. Simply because what we learn can help future health and the health of all human beings on this planet.

Let's face it, technology transfer from research NASA has transformed the way we live and work. It's amazing and nobody can deny that much of our modern facilities have come from space research, as the materials used in everyday life, to the technology in our car air-conditioning systems. In fact, a lot of technology transfer is also from research military technology; the Internet, satellites, nuclear and transport jet aircraft.

Anyway, I hope that I will consider it.
