"Brown dwarfs" are total BS

[SaltyNuts]

They are supposed to be "failed stars" because they don't have enough mass to ignite the fusion in their core. Oh yea? You know what else doesn't have enough mass to ignite fusion? Jupiter. Saturn. Earth. There is no such thing as a brown dwarf. They are just big planets, like Jupiter. When did science officially jump the shark?

Brown Dwarf stars are dense objects that have sun like elements that fall between 20-80 times the mass of Jupiter. They generate enough heat to shine in the infrared spectrum but are not dense enough to maintain fusion.

All planets are just suns that haven't realized their full potential. They taught us that in kindergarten around here. Duh.

Its almost like you, you know, read that on some forum and are just repeating it. The ONLY reason "brown dwarfs" shine in the infrared is because its the leftover head from their formation still slowly seeping away. Where as the heat from Jupiter's formation, Earth's formation, etc. has already seaped away long ago. I'm telling you there is no meaningful distinction between a Jupiter and a "brown dwarf", other than mass. Take a Jupiter, add more mass. It doesn't make Jupiter fundamentally different, just bigger. But at some point the science bizzaros would say "wow, look at that brown dwarf!". No, its just a big planet.

Hah tell that to Pluto.

That's not a morbidly obese person, he's just a big dude.

You are not the authority on classifying astronomical bodies.

No, it is not because their the leftover head from their formation still slowly seeping away. It is because they are generating heat through gravitational contraction, same as any other star. The reason that fusion starts in other stars is because they are so dense that they generate enough heat to start fusion in the hydrogen that is plentiful in the star. Try to do the same thing to the Earth and it would never start fusion because our core is iron and iron fusion has a net loss of energy.
