what

>>11403901
Maybe they're referring to the heliopause?

>>11403901
this is why we don't see intergalactic civilizations. the outer edge of all solar systems is impenetrable. everyone is stuck in their own worlds until their sun stops working and they all die.

>heliopause is 50kC plasma
That's retarded. The heliopause is merely the place where the solar winds run out and the interstellar (galactic) winds take over. Voyager 2 became the first man-made object to pass beyond the heliopause in 2018, and it was able to detect a change in interstellar "pressure" (the types and amounts of particles it encountered).

As a side note on the difficulty of interstellar travel, Voyager 2 is one the fastest man made objects and it took nearly 4 decades to reach the heliopause, and it will take that long again to reach the actual egde of the solar system (where interstellar gravity becomes stronger than Sol's gravity), and it would take 50 times that again to make it to the nearest star. That means the earliest Voyager could encounter another star is in 2420 or so.

your image is obvious EU conspiracy shit. it's false and shill crap

I thought it was the boundary of where solar wind meets cosmic radiation. Though either way temperature in space is kind of silly because you are hardly touching any particles, so, while you will hit a few ultra high energy particles, the total energy absorbed will be low due to the ultra low mass.

Is flat solar the new flat earth

>>11403901
It's like 2 atoms per square km i.e not dense at all and easily penetrable.

Alien quarantine.

Oumuamua was extrasolar

Looks like typical half fact bullshit someone pulled out of their ass.
