What’s the Minimum Number of People you Should Send in a Generational Ship to Proxima Centauri?
Universe Today ^ | 06/14/2018 | Matt Williams

Dr. Marin and Dr. Beluffi begin their latest study by considering the various concepts that have been proposed for making an interstellar journey...also took into account missions that will be launching in the coming years like NASA’s Parker Solar Probe. This probe will reach record-breaking orbital velocities of up to 724,205 km/h, which works out to about 200 km/s (or 0.067% the speed of light).

With their baseline for speed and travel time established – 200 km/s and 6300 years – Dr. Marin and Dr. Beluffi then set out to determine the minimum number of people needed to ensure that a healthy crew arrived at Proxima b.

“We are using a ...stochastic Monte Carlo code that accounts for all possible outcomes of space simulations by testing every randomized scenario for procreation, life and death. By looping the simulation thousands of times, we get statistical values that are representative of a real space travel for a multi-generational crew. The code accounts for as many biological factors as possible and is currently being developed to include more and more physics.”

These biological factors include things like the number of women vs. men, their respective ages, life expectancy, fertility rates, birth rates, and how long the crew would have to reproduce. It also took into account...accidents, disasters, catastrophic events, and the number of crew members likely to be effected by them.

They then averaged the results of these simulations over 100 interstellar journeys based on these various factors and different values to determine the size of the minimum crew... of 98 crew members would be needed to sustain a multi-generational voyage to the nearest star system with a potentially-habitable exoplanet.

All the Democrats, illegal aliens, and globalists I can find.

They need to hire an Anthropologist or two, because that number (98) is way too low.

Send whatever number of conservatives so as not to contaminate the new pioneers.

Well, they put animals on the endangered species list when they have only 10,000 still kicking.

Best bet would be to send a planetoid populated by four exogamous clans.

I used a stochastic Monte Carlo code to play roulette.

Lost everything.

it doesnt matter, the descendants of the originals will have no attachments to Earth, and will not fulfill the mission.......

Let me run this through the super computer.

The answer is.....16 trucks.

6300 years?? Humans would have been there and back long before the descendants would arrive. Likely they would be intercepted and offered a choice of destinations.

Specious profundity on an interstellar scale.

Of course!

The stochastic Mustang Code!

Now it’s all so clear.

The speed of light is too slow for interstellar travel, and the amount of energy required is infinite.........

Maybe.

We all like to dream about super-fast interstellar travel, but barring a miracle, the speed they’re talking about is probably not likely to be improved upon very much.

On the other hand, 6,300 years is plenty of time in which civilization on Earth could collapse completely. In which case space exploration will come to a screeching halt while our intrepid colonists (and there descendants) are in transit.

My old Monte Carlo was very stochastic on cold mornings.
