Earth in space is like a Small island in a large ocean?!?

Well if you look at it from the perspective that we have 8 planets and 166 moons on this side of the galactic disk, and who knows what's on the other side of our galaxy, then yes, Earth is but an island.

The trick to colonizing them is to build dynamos on the globes that spin on their axis. A dynamo may be as simple as boring a shaft and pouring in some molten iron, followed by some water and Sodium (Na), or adding some radioactive elements. This creates the magnetic field that's needed to shield inhabitants from x-ray, gamma and cosmic radiation. It also protects any water from being photo-dissociated by solar uv. On globes that don't rotate, like Earth's moon, we'd have to insert a Superconducting Ring, ranging from 4 to 14 Tesla, depending on how much iron/nickel is resident in the core to begin with.

Too much water and CO2 is being created on Earth from combustion of fossil fuels...so it's sink or swim.

that is not a very good simile

more like "earth is like a single subatomic particle in a large ocean"... if that

supposedly, within 5 seconds following the big bang, the universe was already a billion times larger than the earth

The analogy is a fair one. Only keep in mind that comparison of island to ocean is nothing like the comparison of a planet to the cosmos. The universe is an abyss far greater than we can ever perceive.

Earth is like a VERY small island in a VERY large ocean.

Earth is a few million square miles of land in millions of billions of trillions of cubic miles of empty space. Space is really extremely, unimaginably, hugely, gigantic and empty. REALLY big and REALLY REALLY empty. I mean R-E-A-L-L-Y big. 99.99% of the people have no idea at all how big it really is. If they did, they would never wonder why we don't just make a rocket and go there.

Think about an island in the ocean:

- no other land nearby

- the ocean isn't easy to cross (you need special equipment and if you aren't careful you could die)

- no way to communicate with other islands except by light (and you don't know if there are people over there anyway)

- people leaving the island to explore may never return

Now think about the Earth in space:

- no other planets nearby

- space isn't easy to cross (you need special equipment and if you aren't careful you could die)

- no way to communicate with other planets except by light (and you don't know if there are people over there anyway)

- people leaving the Earth to explore may never return

It simply means that...in the vastness of space..Earth is just one very small speck of debris floating in a presumably endless ocean.

a Island usually means a galaxy. Earth, as a planet, is a very tiny sand on a island.... kinda funny >_<?

the earth is only a tiny speck of dust in the universe.

ha, u could say that. i agree. considering how much water covers this big ball....... an island surrounded by water.

no

its like a unicelular organism in the ocean
