In a series of new studies, a pair of French researchers tackle the question of how many people would need to be sent on an interstellar journey to ensure that a healthy crew arrives.

The radial vector for Alpha Centauri (and orbiting Proxima) is negative. The vector math will put the trip at under 6,000 years at 200kps, not the 6500 years.

What will be more likely an issue is that if we think we could double this speed in another, say, 100 years, then we would beat the 200kps ship by over 2,700 years.

Enjoyable article and nice artwork. I like the asteroid-like shielding.

Fraser, please, just registered here so you can tell me that you realized that they'r doin it wrong.

This flawed approach from the start is the same as Sliders S2E02 Love Gods (http://sliders.wikia.com/wiki/Love_Gods)

The group arrive on a world where biological warfare has killed off most of the male population. Those who have survived are rounded up by the authorities and kept confined in "breeding centers", where they are forced to produce children with "acceptable" women in order to rebuild the population

Forcing parity to a 50/50 male/female starting ratio and focused on reproduction is not scientifically justified but a politically correct autoimposed social construct.

Since long ago, no actual living males are needed just to breed. That problem is fully solved since the past century. Females awake may still pose a mental health problem. But as of today only living wombs are still physically indispensable to breed.

All the necessary genetic diversity can be frozen (http://stargate.wikia.com/wiki/Scorched_Earth), even in the millions, from the origin. In the best case scenario Fibonnaci proves that a single woman arriving at the proper destination could be just all that is needed to exponentially bootstrap a fullblown civilization (and not only human) in just a couple of centuries which is a fraction of the hypothetical travel time.

Once artificial wombs are a reality only a minimal maintenance crew to keep the machines working during the travel would be all that is needed unless that by then AI and robots do the job (http://stargate.wikia.com/wiki/Tin_Man).

Today Noah's Arc only has tickets for females.
