Why are the astronomers so lame? It is likely that there is a gas giant in the Oort cloud and yet none of them can spot it.
you wouldn't be able to see the tiny planetesimals 2 light years away...
it's like the asteroid belt. people think of it as some dense field of asteroids but the whole asteroid belt's mass is ~4% the mass of the Moon...
it's just a region that contains a lot of asteroids
>a gas giant in the Oort cloud
Two of them, one (at some 9000 AU) is about half the size of Jupiter and the other (at 17000 AU) is about 60% the size of Neptune. Both are in the outer (spherical) part of the Oort Cloud. There's also a solid matter planet at 6000 AU which is about 90% the size of Earth. Plus a Brown Dwarf. Source: Aliens.
>Aliens are on planet X
Thats so fucking nonsensical I can only imagine the people saying that are the same people talking about extraterrestrial lifeforms as though they're angels demons and deities.
>There are no aliens in the Solar System
>thinking there are aliens in the solar system
Gorillions of cubic miles of absolute nothing. They think there could be microbes or microscopic multicellular organisms on europa, those kinds of aliens sure.
But there is no extraterrestrial life that isn't so small and quiet as that. There are no cries of, "Ayy lmao" echoing through our star system.
>Moving the goalposts
You declared that there are no aliens anywhere in the Solar System. I pointed out the mainstream belief that there could be aliens on Europa, you come out with "hurr they don't count because they don't have flying saucers!"
This got me thinking.
What is the probability of planet sized objects forming in interstellar space?
I mean should we be expecting to find many cold gas giants far away from stars or virtually none?
Surely many accretion disks can form without resulting in enough mass for a star right?
>Nigga even NASA thinks that there could be aliens on Europa
When you say "aliens" it doesn't really imply bacteria, or even space-squids.
It implies they build stuff like flying saucers.
>Inventing an agreement about assumptions that we never made
>so you can pretend a fallacy was made and act like a pretentious cunt.
I assumed we were talking about flying saucer aliens, nigger. Communicating poorly doesnt make you smart, in fact, it makes you retarded.
Thank you for the key word. It's weird the probability of encountering one of these during interstellar is -astronomically- low, yet the fact that it's there is just unsettling.
Also reading up on this freaked me out even more
>It is calculated that, for an Earth-sized object at a kilobar hydrogen atmospheric pressures in which a convective gas adiabat has formed, geothermal energy from residual core radioisotope decay will be sufficient to heat the surface to temperatures above the melting point of water. Thus, it is proposed that interstellar planetary bodies with extensive liquid-water oceans may exist. It is further suggested that these planets are likely to remain geologically active for long periods, providing a geodynamo-created protective magnetosphere and possible sea floor volcanism which could provide an energy source for life.
>So does this mean an Earth sized planet in the Oort Cloud could have oceans?
Apparently so. I was pretty surprised at the results but based on the assumptions they made such a system would be short lived I think.
With the lack of light in the Oort Cloud it will be hard for humanity to say for sure if a gas giant does exist out there. However as technology develops I'm sure we will eventually find a way to observe if there is a gas giant. In fact there has been a discovered rouge planet that has the possibility of containing life in similar conditions to what this gas giant may be in. A description of this theoretical planet would be a giant ocean based planet covered with a thick layer of ice and underneath would be an ocean and at the very bottom of this ocean life may be able to sustain if the planet has a molten iron core. Interesting stuff but to answer your question the only reason we cannot see this giant is due to the lack of light in the Oort Cloud.
