This thread reminds me of this:
Your video expresses your point but I think its nonsensical. For once, if we get wiped out we're probably just being replaced by an equally worse species. So I'm not sure where you would get your satisfaction for "a better universe of peace and love". If such a human concept can even exist without said humans.

More like 50-100 years.

There have been concepts since about the 70s (getting more and more feasible) to accelerate a probe to on the order of 10% of the speed of light which would do the job, there just happens to be no money for it and we have a mental block about launching things into space that have the word "nuclear" in them.

It's not a mental block, it's a result of rational analysis. Building a large nuclear arsenal and sending it into space is a huge security risk (I'm guessing we're talking about Project Orion type propulsion). It's not a route we should aim for, especially in the current environment. Plus there are probably other options that are feasible, like solar sail driven by lasers from Earth.
On a general note, worrying about unquantified risk is not irrational.

This thread reminds me of this:
This stance is short sighted.
Yes, there are habits and customs on Earth that are surely not worth spreading, but rolling over and just die is not a solution (as kind of proposed by the last statement). People tend to ignore that culture and societies will evolve (maybe not as fast as technology), but it sure will evolve - unless we kill ourselves during the process.
Alas, if this comment was not somewhat ironic/sarcastic I have to just say that cultural pessimism is something that is over"hyped", if I may use this term.

I can't believe the US aren't trying harder to bring freedom on these planets

i love all this stuff and its great but its all pointless!! its too far to even our nearest dead planet! All too theoretical . . .the wonder i think keeps us going!

Saying Project Orion type propulsion is not a route we should aim for is ridiculous, we should use whatever means we have at our disposal!

^interesting read.. I'm feeling a lot more confident about the future of space travel :D

The Drake Equation:
N = R* • fp • ne • fl • fi • fc • L
Where,
N = The number of civilizations in The Milky Way Galaxy whose electromagnetic emissions are detectable.
R* =The rate of formation of stars suitable for the development of intelligent life.
fp = The fraction of those stars with planetary systems.
ne = The number of planets, per solar system, with an environment suitable for life.
fl = The fraction of suitable planets on which life actually appears.
fi = The fraction of life bearing planets on which intelligent life emerges.
fc = The fraction of civilizations that develop a technology that releases detectable signs of their existence into space.
L = The length of time such civilizations release detectable signals into space.
Oh and don't forget the Goldilocks Principle

The issue with that is the assumption that after the civ no longer exists, we wouldn't receive messages. We should be able to capture signals left long after civs go extinct. In theory, the number of extinct civs should far surpass extant civs. Since we've found no such communications, there must be some other problem. Perhaps related to dark matter or supersymmetry?

Like fermionic dimensions in spacetime?

might've made a mistake ( though i don't care ), but based on the fact that light from sun to earth goes for roughly 8 min, this planet is only about 344*10^12 km from here and which is only 2 299 500 times further

A team of European astronomers has discovered a second planetary system, the closest parallel to our own solar system yet found. It includes seven exoplanets orbiting a star with the small rocky planets close to their host star and the gas giant planets further away. The system was hidden within the wealth of data from the Kepler Space Telescope.
KOI-351 is “the first system with a significant number of planets (not just two or three, where random fluctuations can play a role) that shows a clear hierarchy like the solar system — with small, probably rocky, planets in the interior and gas giants in the (exterior),” Dr. Juan Cabrera, of the Institute of Planetary Research at the German Aerospace Center, told Universe Today.
Three of the seven planets orbiting KOI-351 were detected earlier this year, and have periods of 59, 210 and 331 days — similar to the periods of Mercury, Venus and Earth.
But the orbital periods of these planets vary by as much as 25.7 hours. This is the highest variation detected in an exoplanet’s orbital period so far, hinting that there are more planets than meets the eye.
In closely packed systems, the gravitational pull of nearby planets can cause the acceleration or deceleration of a planet along its orbit. These “tugs” cause the variations in orbital periods.
They also provide indirect evidence of further planets. Using advanced computer algorithms, Cabrera and his team detected four new planets orbiting KOI-351.

Hi guys, i'm a Astronomy student, i'm still in diapers here (finishing first year), and i'm in love of exoplanets and life beyond earth, i'm about to give a speech about exoplanets ( it will be tomorrow!~) and i have recompiled quite a bit of info about the theme, anyways because of the trend of talk is moving more and more towards life i feel you would like to have a look at these pictures, they are a bit old for today's standards but i feel they will be good enough for you guys ^^
![[image loading]](http://i.imgur.com/UXCRaEV.png)
I'll let you guess where Kepler was pointing at ;D
+ Show Spoiler +![[image loading]](http://i.imgur.com/DRNW2lq.png) Go to phl.upr.edu for more stuff, they have A LOT of pretty amazing media and quite a bit (to say the least) of solid scientific data too!
Also, NASA/Kepler guys are trying a quite interesting method to bring back Kepler from the dead!, it a extremely smarty pants method and i love it!
So yeah, Zombie Kepler ftw!

I hate to be a pessimist but I'm pretty sure every government on earth would burn babies rather than release any real info out to the public. Some things are worth more than money and its fun to speculate but they're not even sharing the money what makes any of you think they'd share their secret knowledge bombs with us lowly folk?

Good thing organizations like CERN are unaffiliated with any governments!

It's not pessimism it's acute paranoia.
Why would "governments" hide anything to anyone regarding planets that are light years away? That doesn't make sense. It's not like you could travel there tomorrow morning. And even if you could I don't really see what difference it would make.
You guys watch too many TV shows.
