'Second Earth' found, 20 light years away

[Jono]

Well thats an easy one, as radio waves travel at the speed of light, It'll take 20 years for a signal to get there, and 20 years to get back. So at the moment if there is life on that planet, they are suffering our late 80's music so they probably think we're attacking them already.

PK!

<Insert Deity Here> help us!

Wow, very cool. I've always been convinced that there has to be life "out there" somewhere... just way too many planets to try and check.

20 lightyears = 1.89210568 × 1020 millimeters

1.89210568 × 1020 millimeters is just under 2 meters

 

[SiriusB]

Easier just to say 3 x 10^8 m/s

c would be even easier

 

[Samione]

1.89210568 × 1020 millimeters is just under 2 meters

He probably meant 1.89210568 × 10^20 millimeters

 

[Dracata]

I think its a fairly likely thing that there are thousands/millions/billions of other 'life supporting' planets out there considering the number of galaxies and star systems in the universe, this backs that up

 

[Kreeeee]

the "aliens" there set off here in a big ark just under 20 light years ago

Light years is a measure of distance and not time.

Edit: I forgot to refresh the thread

I did, yup, edit inbound!

It'll be as useless as this one is by the time we'd get there... hell it probably already is, we're looking at it 20 years ago...

Allways loved this youtube video, watched it again after seeing this thread and still makes my mind boggle!

 

[Lord-Jaffa]

Wasnt this already posted quite some time ago?

Only to life as we know it.

There may be life that is based on some other molecular compound, but it is difficult for us H2O based lifeforms to imagine what they might be like.

its pretty much water = life

water has many unique properties that nothing else has (i guess thats why i said unique!! ). Its hard to see how any complex molecular system could evolve that didn't involve water or carbon.

Do radio waves never stop or do they run out of steam so to speak?

 

[Mat]

they jsut get weaker and weaker and weaker to the point where they are undetectable.

How fast can we make things travel in space?

If we sent a satellite on it's way to this place. How long would it take and how long would it take for us to receive signals back from it? (if we could at all)

I want to know if there is life there NOW dammit, not in years and years and years. It seems all these cool stories about space never go any further

The signals will take a mere 20 years to get back. But, even if we wait a hundred years or so for better tech it will take hundreds of thousands of years to send the sat there. Best hope is to wait a thosuand years so we have a chance of doing some funky phyics...

 

[panthro]

hopefully it might just be able to give us world ruining lot a second chance.

A second chance at ruining another planet would be more than likely judging from human nature and the way the planet is heading

never stop (in a vacum, without mavity)

Yes, but as far as the aliens are concerned it will be big news in 19 1/2 years.
