All the information you can gather due to your "astro" connection, everyone else can also aquire from the web. Drop the "astro-ego"...
1) A brown dwarf is a gaseous body made up mostly of Hydrogen and Helium. They are thought to form in the same way as stars but because of lower mass they do not reach the required temperatures to achieve Hydrogen fusion, so they support there rotation through gravitational shrinking. They are assumed to be very similar to M-dwarfs in the early stages of their lifetimes, but as they grow older they shrink down and become much less luminous. The biggest (youngest) brown dwarves are just a bit smaller than a main-sequence M-Dwarf, and the smallest ones are about Jupiter sized, maybe a bit bigger.

2) At 60 AU from a brown dwarf, even if it was the biggest brown dwarf in the world (which would make it about 5 times smaller than the Sun at best if memory serves me right) the amount of light you would get is pathetic. Pluto is much closer to the Sun than 60 AU (somewhere between 40-50 AU, that is the near section of the Kuiper belt which pluto belongs to) and the Sun is much brighter than a Brown Dwarf. Pluto's Temperature is something like -220 degrees celcius. Does that answer why such a planet could never be habitable? If it wasn't enough, Brown Dwarves lose their luminosity rapidly. Life takes Millions of years to develop if the Earth is any example. If we waited millions of years with a brown dwarf, it would be already too faint. It's also unstable due to gravitational collapse.

3) Size of the parent star matters, because massive stars die early (Main sequence lifetime of a few hundred million years) so no massive star hosted system can have light (they are also way too luminous). Small stars are usually too faint. So really, by spectral class alone, many stars are not even candidates.
Same stuff goes for temperature. Only use irony when you have the required knowledge to back it up

4) No comment. Jesus also insults people because he has superior knowledge. He's a clanmate, I know

If you think that being able to browse the web makes you an astrophysicist, you're welcome to try and do my job.

<-- just learned about class M L T Y brown dwarfs (almost put dwarves)

http://en.wikipedia.org/wiki/Brown_d...f_brown_dwarfs

Put aside the idea of life evolving near the brown dwarf. What if life moved near the brown dwarf to exploit the elements located nearby? Life that can thrive in a habitat that they can manipulate and sustain with interstellar capabilities can do as they please.

I know your Jesus!!!! Long time no see though..

Science changes its views based on whats observed.
Religion is the denial of observation so that belief can be preserved.
I can't believe (no pun intended) I'm defending the religious perspective when once I used to be just as opinionated as you in my denial of all things religious.
This would be the point I was making, what we may know now - we may know differently in the future, this has been a common occurrence throughout history.
For example, a good portion of Darwin's work has been refuted and revised in the past hundred years since he published his book - that is, he wasn't wrong on a few issues but nor was he right.

It's also not exactly fair to say one thing is true of a large swath of people.
The bible is yet another example of old "knowledge" proven redundant.
You may feel adamant in your conviction that you're right but I'm guessing so did everyone else back eons ago when the only explanation was biblical scripture.
My own mother for instance, is quite religious but she also takes science into account to create a bastard explanation for the genesis of existence - she will say that perhaps there was such a thing as the Higgs-boson before The Big Bang, perhaps life did evolve as Darwin proposed but who's to say this was not all to some grand design of said deity? We certainly cannot prove this is wrong the same as we cannot prove it's correct.
Belief does not blinker one as a rule to the contrary, it's only certain individuals themselves who chose to ignore other explanations - this is their right, as much as it is our right to treat such people with contempt

Belief was also the sticking point personally, it is not enough for me to just believe something exists.

Hey hey how did I get involved in this? .Epic posts guys keep it up

P.S:Stop trolling dalla ppl start taking seriously into account what u say..."I'm a scientist and its my job!."LMAO!!

See? That's the difference. I don't need to go to wikipedia to know this stuff, it's all in the back of my head to call forward when discussions such as this happen

You need to realise something about the Earth and life. Life evolved on Earth because it was suitable, but it also changed the Earth through interacting with it. A clear example of this is the Earth's atmosphere. Normally, a rocky planet would have what we call a "secondary atmosphere" - made mostly out of Carbon Dioxide, like Venus's (and like Mars's, although that has been depleted now). The Earth has a "tertiary atmosphere" - because of the evolution of life, our atmosphere is now mostly Nitrogen and Oxygen. Without life, this atmosphere cannot be developed.

What you're looking at is a concept called "Terraforming" - manipulating a celestial body in order to make it Earth-like. In most cases, it would mean that you would have to find a body with plate tectonics and a powerful magnetic field, manipulate its atmosphere, deliver water, etc... I once did an essay on the subject... and it felt more akin to Sci-fi than Science.

By the way, planets receive energy from their parent star. Moving close to a brown dwarf would mean suicide, since the energy would just keep decreasing.

@jesus. Shut up. I said nothing of the sort.

The story resembles ice.
People are far to sensitive over these issues, you wonder why I said this?

What about the test they did with neutrinos? They were faster then light right..

Also, don't worry about what people say. This is the inn and we can post as we please. If they don't like it they don't have to click it. Some people are exactly like those that died on the titanic refusing to accept that the ship was sinking or was sinkable.

Personally I am interested in finding truth in all areas of this so called life, so keep on finding and posting for the people!
Totally agreed lol, really if people don't like it they shouldn't click on the thread.. Not so hard I think.

I watched it but the guys who are presenting the video aren't really serious about this issue, which makes it less interesting Unfortunately, anyway.. So it is possible.. Wow, amazing what we can do nowadays.

I can't believe that there really are people believing in this crap. On the other hand, there are tons of creationists in the USA, too, so... :P :P Believing in Nibiru is quite tame in comparison.

Statistics. Rare events do happen. Simple math. Counter question: Why should we be something special? The universe is huge.
If you hope to meet them one day though - you should start playing Lotto. Waaaayyyyyyy better chances. ;-P Way better like in... I got nothing. Just forget it.

Oh, and there is no way to move something faster than light. Not matter, not information. Nothing. Yes, there have been neutrinos that seemed to be 0.0025% faster (lol), but that's most likely a measurement error. Anything else?

In general, it is stunningly similar to the Earth - other than the fact that its Hydrosphere is made up of Methane, not Water. Too bad. It's still speculated that there might be microorganisms that use Methane in Titan, because its methane levels are constantly being replenished (although it might not come from biological sources). And it probably has a subsurface water ocean like Europa.
I like those kind of theories. There have actually been found organisms made of other stuff than the normal elements (was it boron? lol there's nothing I know less about than chemistry) if I remember correctly, and why should organisms even need water? It is 'assumed' yes, but in fact we know nothing at all.

That's where you can believe if you want to, it might be possible after all, even with everything we know (which obviously isn't that much). Humans tend to make things they don't know up. We made god up because we couldn't imagine how something like life (or anything in this world actually) could ever happen on its own, but now we know, no need for god any more, guys. Believe whatever you want to, as long as it doesn't collide with sanity. :P

It's not that simple. But it can be proven, at least in a way that you can't disprove it. Every maths student has to go through that. :P
That's where science is religious, we believe that there is logic. Is it necessary, that the whole universe follows logic? No, we want to find out. It's the same with religions IMO, they've just stopped waaay earlier. (Religions follow logic, too! Humans need logic)


Interesting thread I've missed here.
