Why cant we live on other planets?

Question

Why cant we live on other planets?

Answer 1

There is no oxygen to support life.

Answer 2

because we are made to live on earth its no necessary that we dun have living elements there but we are not suitable for there like we have water oxygen food sun light every thing in sea but we cant live theer so think about it

Answer 3

Oxygen, water, food...

Answer 4

Most planets that we know about can't support life either because hey don't have an atmosphere and water with air or they are too hot or cold.

Answer 5

Because the authorities want to keep us here on Earth where they can control us. They won't let us leave and likely tell us lies about how other planets are inhospitable.

Answer 6

Here a brief list of reasons why we can live on each of these planets:

Mercury:  Too hot in the daytime, too cold at night, with no atmosphere to protect us from deadly radiation.  Also, no water exists there in any appreciable amounts.

Venus: Even hotter than Mercury.  Surface temperatures hot enough to melt lead.  Crushing atmospheric pressure.  Again no appreciable amounts of water in any state.

Mars: Probably the only other planet in our solar system is that even conceivable to live on.  However, it does not have LIQUID WATER in any appreciable amounts though there is ice at the Martian polar regions.  The atmosphere is not of the right elemental composition to support human life.  Many many other factors would in addition make human life on Mars very difficult (ie poor soil, sand storms etc)

Gas Giants:  Well for starters, they don't have a solid surface so that takes out any chance of humans establishing life there anytime in the forseeable future.  Again, no water in any appreciable amounts.

Pluto: Oops no longer a planet :P

As you can tell the issue with water is a very fudamental requirement which is lacking in its most useful state on all planets in the solar system besides Earth.

Answer 7

Other habitable planets are already occupied.

Answer 8

how about the simple fact that WE CAN'T GET THERE!

there' s big difference between sending a small robot to Mars and sending an entire colony.

we can BARELY do the former, the latter is quite impossible, especially as we spend most of our money on war and tv.

Answer 9

When God made man ,He made him a body that is only adaptable to this planet.Our atmosphere got a lot to do with it.There will be a time in the future that god will give us some new bodies that will be able to not only live on other planets but travel there. I am not talking about taking a space ship up in space.Read it in the most important book in the world.

Answer 10

No one has said we can't live on other planets.

The planets we know about in our solar system don't have all the things humans need to survive (water, the right temperature, oxygen, etc.).

And we don't know enough about any of the planets found in other solar systems yet to determine is we could live there (the ones found so far don't appear to be habitable, they are either too close to their suns and therefore too hot, or they are so massive that we wouldn't survive the surface pressures).

Answer 11

Other planets would either be too hot or too cold. The atmosphere on one of the planets has storms like tornadoes a lot.

Answer 12

Morally, because we can't even look after our own planet. Technically, what they said.

phntmMd that is not correct. We have discovered plenty of liveable planets that are primordial.

Answer 13

we can't live on mercury because it is either way too hot or too cold, depending on location, as well as having no atmosphere, and no air. it has no oxygen, carbon, anything. and any gases we put on it would evaoprate into space because, again, mercury has no atmosphere. it also has no water.

we can't live on venus because it is a hot volcanic wasteland. it has a very thick atmosphere due to an irreversible greenhouse affect, and became a volcanic h**l. it has no water, and has mainly carbon doxcide. plants couldn't live on it, because it is too hot, so we couldn't oxygenate the planet. and even if we did, its way too hot. its the hottest planet in the solar system.

earth is special. it is just the right distance from the sun. it also has a large amount of water, as well as rocky land masses with a temperate climate. earth is our solar system's eutopia.

mars is a possibilty for future colinization. we can heat up mars, and over the period of millions of years, get the planet natuarally oxygenated by introducing plant life after we warm the planet. its ironic in a way- we want to stop global warming on earth, but we want to induce global warming on mars. we can't live on mars now because it is way too cold. its average temperature is 150 degrees centigrade. thats cold. it also has no significant water depositis. it has some, but not enough to quench mankind's thirst. it also has a very thin atmosphere, but inducing global warming on it will warm it up by thickening the atmosphere. so mars is a possibility for future colinization. mars curently has no oxygen, but is filled with carbon dioxide, so if it was warmed up a little, it could support plant life to an extent.

jupiter is a gas giant. the only solid part is at the core which is extreamily hot. it has extream weather patterns, and that combined with its gravity would rip anything that landed on it apart. it is also very hot, and is just not a very good destination for mankind. this planet has the second fastest wind speeds in the solar system, with neptune at first place.

we can't land on saturn period, much less colonize on the planet. it is also a gas giant like pluto. the core, which is the hottest part, is the only solid part. there is no land on saturn. it also has, like jupiter, extream weather patterns. there is no place on saturn to land.

we can't colonize on uranus because first of all, it is too cold. its so cold that most of its gases are in a liquid form. it has an ocean of hydrogen among other gases. uranus can't sustain any life. it has no water, no food, no oxygen, nothing.

we can't colonize on neptune either. it also has no oxygen, water, food, or anything else needed to sustain life. it is a gas giant, and the core is the only solid part. it also has extreamily turbulent weather patterns. it has the fiersest winds in the solar system.

pluto has nothing. its too cold, has no water, has no source of food, and has no oxygen. it might not even have an atmosphere.

mars is the only planet we could possibily colonize on. earth is the only planet that can sustain life in its current state.

Answer 14

Cause some planets don't have the elements to support life live h20, o2, etc. But bacterial life can thrive in the most harshes of elements.

Answer 15

Because they're lacking things that we need to live - water, oxygen, plants, things like that.

Answer 16

We haven't spend the money and effort to build habitats there yet.  The habitats have to be airtight so it will be very difficult to do.  The US does have plans to build a base on the moon soon and send people on a short trip to Mars and back.

Answer 17

it has to have tolerant conditions not 2 hot not 2 cold. plus it costs a lot of money to develop and research new space colonies. and we are still not sure the long term effects of zero gravity, which is being tested now on the international space station. =)

Answer 18

in order for us to live on another planet it would need have have similar conditions in order to support us.

Answer 19

Because we don't posess the technology yet.
