Our possible next home.?

Question

I've been reading a discussion about our next home after a few hundred million years at http://zaine7673.proboards104.com/index.cgi?board=astronomicaldiscussions&action=display&thread=1169131078 I was wondering, wht are the facts? as far as I know there looking at mars....

Answer 1

watch "total recall" . do you think people could maintain a dome?

Answer 2

i believe that mars would be a good future home for humanity. It was an environment that is currently unsuitable to mankind but there are some designs for terraform projects on the table as we speak. If you want to talk about millions of years in the future then it is very possible that mars could be terraformed into a very much habitable planet. There are already huge concentrations of water on mars in the ice caps and underground in what is refereed to as permafrost. I think it is unlikely that humanity will be able to colonize worlds in any but the closest solar systems. this is due to the light speed limit. this is a law of physics and no new technology will be able to break that limit. Matter simply can't move that fast without requiring infinite energy. our next home will be mars you can could on that.

Answer 3

it would take about 150 years to terraform mars, slowly changing it into an earth like planet.
there should be colonies on it within the next couple of centuries.
now when you thing that just 400 years ago, Europeans knew nothing about the American continent, that 100 years ago there were only 8 planets in our solar system and that 10 years ago we didn't know if there were other planets orbiting other stars in our galaxy, i think it's a safe bet to say that in a few million years we'll have migrated to thousands or millions of worlds across the universe.

Answer 4

Truth be told, Mars is probably the most suitable home for humans. It is large, larger than the Earth itself, and still does get a considerable amount of sun time. However, Mars is desolate and has no water, and the temperatures there can reach extremes from night to day. It is very unsuitable as it has no atmosphere that is thick, and so an asteroid, even small, would be a serious threat.

Answer 5

Mars is too far for us to travel to regularly so the moon is our only option. A new home would need economic funding so I can see a hotel/scientific colony on the moon mostly underground to give added protection

If we can survive in a station in the south pole the only difference between that and the Moon is the cost of the trip which could be paid for by the lunar tourists

Answer 6

A few hundred million years is a little far to tell. We could have evolved or self-augmented ourselves into anything in that time. Proto humans have only been around one or two million years already, depending on where you start counting. Putting that aside, planets are fairly fragile ecosystem, I think we will probably build our own habitats in space eventually, instead of relying on planets. A dyson sphere, for example, is probably something on the order we could build in a few hundred million years.

Answer 7

By the time a few hundred million years have passed, humans will have been killed off until completely extinct then will have repopulated the earth several hundred times over.

Civilization will never become that advanced before being almost completely annihilated....natural disasters will always ruin our technological advances.

Answer 8

the problem of human life leaving earth for a new home is not centred around us being able to find such a place but around us being able to get there. the nearest star with a 'usable' planet is barnards star. to get there we would need to accelerate for some 23 years, then decelerate for 23 years. ( using recent theoretical technology). the top speed we would acheive is 12% speed of light. but the issue is one of inertia; to accelerate/decelerate at the required rate to get a human from here to there with time to breed a next generation, would mean unsurvivable g-forces. ie.coma and general collapse of organ function.
there is no way out, bro. we just better look after this home, unless you can come up with a way to negate the effects of movement on mass.

Answer 9

Would you move in to a unit that the carpet has never been cleaned even it appear no stains? The standard carpet cleaning is done for disinfection, not only to remove stains cos' carpet hidden a lot of germs. The LL can lawfully show your unit to prospective tenants with proper notice to you which usually 24 hours either verbal or written. It is quite disturbing and you can ask to see if your LL can show the unit only on weekend. Tell him/her that your unit is very disorganized and is up to him/her decision to show or not.

Answer 10

Srinidhi V: you said "[Mars] is large, larger than the Earth itself ..."

I think this is not so. Perhaps you meant that the land area of Mars is larger than Earth's (because of Earth's oceans)? But in fact, the surface area of Mars is less than the total area of Earth's dry land.

Answer 11

global warming, is chicken feed...a blip.
The sun goes through phases sufficient to make entire planets unsuitable.
The gap in the darwin therory of mans evolution, is....yes, there was life on earth, yes, it did die out, yes, it was reborn. Part of this cycle, was life became unsustainable on mars, man moved to earth. Life is looking iffy, long term here, mars has stabalised again......and on it goes, with such time differences in between, civilisation actually regresses, and forgets its history, in liew of basic survival.
So althogh our history has forgotten it, life on mars, and earth, is common to man, already.
