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.

LOL good sarcastic post. Global warming kills very few people. Ice age is horrible for mammals and kills millions. And ice age returns every 10-30 millenniums. Global warming ends every ice age. The Sun cycles control earth’s climate, because Sun is a million times bigger than planet earth in volume.
They can't possibly build a space ship big enough to hold all the current America's enemies domestic.
A planetoid with tunnels, caverns, farms and factories, hospitals and academies; all safely beneath the surface. A world unto itself.
A very tightly controlled society broken into for or so exogamous clans but all subject, of necessity, to restrictions on childbearing and employment.
: )
(thumbs up)
They recycled the idea in Next Generation.
Barak Obama and Hillary!
They deserve each other.
Heck, I’d even throw in Schumer and Pelousy
just for grins.
What’s the Minimum Number of People you Should Send in a Generational Ship to Proxima Centauri?>>>>>>>>>>>>>
Forty Six (46)
Laz (1) and the entire Dallas Cowboys Cheerleaders squad (45)
You would be breeding a crew of super-mutants!
Not a problem; they can be useful in other ways...
In the Soylent Green sense...
Send along a supply of frozen ova and sperm. Takes care of genetic diversity along with radiation injury to crew gametes.
That’s the technological solution, not the Christian one.
Yup. Like that.
It will happen. Once a big chunk of humanity is living that way every day within rocks orbiting the sun, pushing one of those towards a nearby star system will be relatively simple.
Why hold back? Send ALL of the freeloaders at the UN, they can start their New World as they see fit, as far away as possible from the rest of us.
One could introduce greater genetic diversity by sending along frozen embryos and stocking the ship mainly with Female breeders.
In 1968 Freeman Dyson calculated that there “Momentum Limited” spacecraft using atomic pulse propulsion could reach Alpha Centauri in 133 years.
“The biggest design above is the “super” Orion design; at 8 million tonnes, it could easily be a city.[12] In interviews, the designers contemplated the large ship as a possible interstellar ark. This extreme design could be built with materials and techniques that could be obtained in 1958 or were anticipated to be available shortly after.”

A little learning is dangerous thing...
Current science has established that real Ice Ages recurrence is in the realm of hundreds of millions of years.
So that statement is ignorant to the point of meaninglessness...
But it does concur with the current idiot "Climate Change" hysterics.
Just sayin'
While I love science fiction after 6,300 years, you’ll have a ship full of dead people.
No way society and education would not deteriorate in that situation.
Heck, we can’t even keep things going well for 200 years on a whole planet.
The minimum?
One hundred - me and ninety-nine Playboy playmates.
