It's not incredible ... it's logical. No :censored: there's a chance for life in any star system. There's a chance that a planet with the right atmospheric conditions would be in a distance range that's not too far but not too close to the star. 

 

It's as logical as saying you have the chance to find the nickel in a mountain of quarters. Yes, you definitely have a chance. Maybe not a great one. but there's a chance.

It's incredible because only 20 years ago, we thought exoplanets were rare. Once we discovered that every system has at least one, we thought they'd mostly consist of gas giants (because those were the only ones we could detect at the time). Now we know rocky planets (like Mercury, Venus, Earth and Mars) are very common. As I posted a couple of months, we now believe 1 out of every 3 planets are Earth-like and we believe most systems have at least 3 planets, so this is furthering our best estimation that there is a Earth-like planet in nearly every star system. That journey from believing planets like Earth were rare if not one of a kind, to believing Earth-like planets are very common is incredible to me. 

 

 

 

There's a chance that a planet with the right atmospheric conditions would be in a distance range that's not too far but not too close to the star.

 

That may not be true anymore, or at least our definition of what is the right atmospheric conditions, may not be true anymore. We think there is a good change of finding life in the oceans on Europa, but even most interesting, there is solid evidence pointing to life (basic bacteria and other microbial life) existing in the methane oceans of Titan, presently. That would change everything in terms of what we think the conditions have to be in order to have life.

I didn't say the right atmospheric conditions like Earth. It's just always seemed logical to me that there would not only be planets like ours that could support life but that there's a distinct possibility that there are forms of life than could exist on conditions totally different from Earth that we haven't had the chance to observe yet.

My wife just got and accepted a job offer that'll pay her about 2 ⅔ times her current job along with actually having benefits AND she'll have the perk of being on the same floor as her dad.

Wait ... 2.67 times the money and benefits? Where is this kind of job luck and can I get some? lol

After nearly 26 years of life, I'm finally able to grow some respectable semblance of a mustache. No more chinstrap. Maybe.

Also, thanks to the crew at BASS for answering one of my questions. You didn't have to do that, but you did anyway. And I'm appreciative of that.

If you hadn't noticed, Chawls loves his wrestling, whether it be real life or sim. :D

 

THIS is the FUTURE of women's wrestling.

Well said, and I couldn't agree more.

For what it's worth, I always thought it was logical that there would be alien life that was similar to us and very, very alien to us. So I understand you when you said it isn't incredible but logical that every system has the potential to create earth-like planets because it really should be considered as logical.

Given the conversation, this seems like an appropriate place for this bit of news coming from NASA today.

http://www.iflscienc...-are-not-alone#
 

 

For the first time, scientists have found what appears to be a rocky world orbiting a Sun-like star at almost exactly the same distance that Earth orbits our own Sun. While other potential habitable planets have been found before, this is the first that could plausibly be another Earth. This might be the real deal, people.

 

Kepler 452b, found by NASA’s Kepler Space Telescope, is located 1,400 light-years from us. It orbits a star that is 4% more massive and 10% brighter than our Sun. The planet itself is 1.6 times the size of Earth – making it a super-Earth – but the scientists are fairly sure that it is a rocky world, owing to its size and the type of star it orbits.

 

Its orbit, 384.84 Earth days and 5% more distant than our planet is from the Sun, places it right in its star’s habitable zone, where it is not too hot or cold for liquid water to form: the same region Earth is in around the Sun. This is not the first Earth-sized planet found in a habitable zone; last year, the world was abuzz with the discovery of Kepler 186f, more similar in size to Earth. But that planet orbited a red dwarf star, smaller and cooler than the Sun. Kepler 452b, excitingly, orbits almost an exact clone of the Sun.

And it would only take us a few million years to get to it! I love this kind of stuff, but until technology catches up to the point where we can send a probe there in a lifetime, it kinda bums me out as well.

Why would we go there? Their star is about 1.5B years ahead of our sun so it's reached a point of making the world too hot and uninhabitable.

I think the idea of "going there" is sending a probe in search of life, not seeking it out as an alternative to earth.

 

Then again, by the time it's actually possible we may have found life elsewhere.

I'm not saying it's a life boat for Earth; if we ever have the technology to move humanity 14 light-years away, we can probably just fix whatever problems we have here on Earth.

Went to my first ever baseball game last night and it was awesome. The Columbus Clippers def. the visitinh Rochester Red Wings 5-4. We even caught a ball and had it signed! Great identities between the two (unis can go die in a hole, but whatever), better game, and an absolutely beautiful ballpark.

Not a Transformers guy, but this is pretty great:

 

 

The only flaw is it doesn't actually become a Genesis. My cell phones since 2009 have been Sega Genesises, and this could have been too. What a missed opportunity.

Remember the random pseudo-Eiffel Tower thingy they built next to the stadium for the London Olympics:

They're planning to turn it into 'the world's largest tunnel slide.'


*Insert obligatory bandwagoning/backslapping of favourite teams successes here*

I get it, I step on people's toes when talking about league structure, fairness, balance, and boring things like schedule format. It's like saying that the Middle Ages never happened.
