A new discovery - perhaps life outside of earth is possible?

Finally. They found a planet suposedly probably inhabitable by us... as in similiar to earth

"Earthlings won't be traveling to Gliese 581g any time soon unfortunately. Scientists say a spaceship traveling close to the speed of light would take 20 years to make this journey."
We don't have a spaceship like this, have we?

Whatever, if we are talking about a population (infestation xD) it would be very difficult.

"Scientists say the highest average temperature is about -12 degrees Celcius (10 Fahrenheit), but they point out that the planet doesn't have a night and day - one side continually faces the star and the other side faces the darkness of space. This means one side is blazing hot and the other freezing cold."

Who would live in the dark and cold area?

Cold all the way. Or just live on the border of both. If you thought lake-view property is high priced wait till we get there.

And I do believe that humans will some day have the technology to travel at light speeds and make the 20 year journey. Just what humans do, we keep going forward even if it looks like we're going back.

Cool
It will be cool if we could go there
but as u say the costs and the risk will be high
but if really will be place colonies between those 2 planets
for supplies and other things
Wouldn't be possible for us to reach ?

It's the most possible way so far but there are some issues. Habitable planets are few and far between us and our potentially new home. More over, some of those places have different kind of gravity so our muscles, bones and various other stuff will be heavily affected. Establishing artificial environment that's fit for human on even one planets will take decades to do.

And I do believe that humans will some day have the technology to travel at light speeds and make the 20 year journey.

Being able to travel at light speed is one thing, but being able to travel safely at light speed is another thing altogether. When you fly at such a speed, you won't see shit so hitting several out of place asteroid is entirely possible. In addition, space has no air so there's no way you could maneuver like when you're on Earth. With that being said, good luck avoiding obstacles.

There's also the breaking problem. How can you stop something that's basically a bullet going at speed of light? Chances are we will punch a rather large hole on that planet or become a giant fire ball ourselves before we can halt the damn thing.

That's why we invented the moon walk.

awesome... but 20 years to travel that for... mhm and i am 17... thats 2 long...

Mmmm.... I don't like how the scientists are "100 percent" sure that life can exist on this planet. Obviously it has a high chance, given its similar conditions and position to Earth, but there are still too many factors to make it "100 percent". For a start, they don't know the planet's magnetic content and structure; should it be too low and unlike Earth's, any possible life would be fried by the star's solar radiation.

I would believe that by the time technology has grown to the point that rockets can move at the speed of light, more simpler technology like RADAR would be quite easily used to detect large bodies like asteroids, and allow the ship to avoid them. Also maneuvering in a lack of air is very possible, it would just require a source of thrust on all sides of the ship

To stop a rocket travelling at the speed of light, you could utilise Newton's Third Law. Make the rocket release something of equal but opposite force to the rocket's own force, like a cannon or something, and the rocket will stop.

What if it's already inhabited?
And according to Einstein we would be converted from mass to energy if we travel at the speed of light.

True, but unlike previous attempts, this is more like a first step, which has a non zero probability of being successful... so perhaps, at some point, after terraformin the planet (lol) well be able to escape the death of the sun by movin the human race to that planet... it is 3x larger (altho one side is hot as hell, while the other is cold as shit)

Even Mars can be a temporary place to stay.

Mars has very less temperature so we need to increase the temperature to make it a place to live and the way to do that is Global Warming!
Plants require Carbon Dioxide which is there in large quantity on Mars so they will grow well over there and will even produce oxygen. Although it's not possible right now, It can be in the near future.

Don't worry, we can just do what they did in Avatar

lol,
That will be evil.

lol, we are superman if we got there!
Ninjahs with supah powers!

We have/are Ninjas... and Wizards... we are Ninja Wizards.

with the present technology
we could travel at 20% of lightspeed
=> we would take 100 years to reach

at mars, the polar regions are said to be covered with snow,
and the temperature their is very low due to lack of green house gases
the atmosphere there is very thin, thus the pressure is low and the atmoshpere is very dust
CO2 is 95%,
.'. thus no human can live

u forgot that smiley

@Zazz
Your way to stop the rocket,you know,it's quite inefective,because we'd need an über-seat belt,otherwise,who knows what'll happen if we stop that fast in the speed of light.

Some squish and squash... and then some blurp afterwards.

Where there is snow there is water.
And we won't go there without space suit -.-!
And since the percentage of Co2 is high and also due to less gravitation the plants will go much more and produce much more O2.

Much more O2 =/= Life (as we know it - humans, animals and e.t.c.) on the planet.

There must be 21% of it in the atmosphere or else no life for you, mister.

Yay they found a planet,now create a gigantic ship for us to go there
