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.

Don't forget to include the hair dressers and telephone sanitizers.
I can’t go back.
They banned me for being a card counter.
I was memorizing the numbers on people’s credit cards.
Hopefully including at least one that knows the difference between "effected" and "affected."
So am I.
that’ll do it every time!.........
Planning on that time scale is beyond us now. Maybe it won’t be a big deal eventually, if we figure out how to extend our lifespans. I read one sci-fi series where the aliens don’t bother to contact ‘primitive one system powers’ unless they can stick to a plan for 50,000 years or so if I recall.

And how many generations of humans will live and pass on before any such question is in need of answering, and what will be the then technical abilities weighing on the question?
That makes attending this question now an execise of scientists with too much time on their hands - hopefully not at taxpayers expense.
Sounds like the plot of “Icarus at the Edge of Time” short scifi story. Google it.........
number of women vs. men,
Isn’t this statement bigoted against the LGBT peoples???
This is hetero normative, and binary, in their assessment of sexual ratios, sexual reproduction, etc. What if there are disproportionate numbers of “gay” peoples or “transsexual” peoples who will be axed out of the reproductive cycles?
Will there be conventional marriage and families raising children in space?
They have to think through many many factors.
Suppose they arrive at Promixa Centauri, and find there are no earth like planets on which to settle? Then what?
Me and Sarah Palin.
No humans needed for this trip to Proxima Centauri.
Just send a “Noah’s Ark” ship, full of many different life species, animal and plants and germs and viruses and bacteria (and whatever other lifeforms there are).
Then, let “nature” take its course...
And “in due time”....
VOILA!!!!!
Humans would have evolved from those original travelers.
(Ask the ‘Darwinists” how that works; we humans on Earth are they descendants of a similar space ship that came here billions of years ago.) ;)
Exactly! Everyone knows all you need is a Winnebago!
Just don't go to ludicrous speed.
Zero. We shouldn’t be going anywhere else
Since I’m a Risk Management/Finance geek who does projects for banks, I actually understood what he was talking about!
(I should probably duck now) :^)
Based on size of Universe, whose end we have not seen yet because it is further than light could travel since humans appeared on earth, there are quadrillion**quadrillion planets out there in the universe.
Humans on earth will become extinct within a million years having endured 100 ice ages by then, but there will be human like creatures evolving in quadrillion planets somewhere in the universe.
Unless someone is supplementing with frozen sperm and zygotes.
Imprisoned women breeders artificially inseminated for the gay overmasters. Strange things could develop on a generational ship in 6000 years. Or at least that’s what sci-fi says.

you do realize that you will live waaaaaay longer in space travelling at such a great speed?.........
Beat me to it. GMTA!
