A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment. In circumstances not amenable to experimental testing, theories are evaluated through principles of abductive reasoning. Established scientific theories have withstood rigorous scrutiny and embody scientific knowledge.

and no, you couldn't observe sun spots on other stars

`theory is that the sun goes through periods of extreme activity`

stars dont do this

yes, pay attention please

Uhhhh how extreme were talking

enough to melt moon bits apparently

how long have we been studying solar activity?

fucking Xtreme my dude

Also don't let him know about CMEs

how old is the sun?

@ManAnimal and how many different stars can we see at a time?

you cannot see sunspot activity on a star other than our own

that's not technically true

that is like studying a flea on a dogs back across the room

you really think that life can evolve in such a short period during the suns "active period" if they even exist

We see variable stars a lot

But those are high variations

Like

yup

also what does glass have to do with anything?

If The Sun was like that the solar system would be sterile... Probably

@Dark Magician regolith turns to glass when molten

that is assuming that such solar cycle actually sterilzes the entire planet

We're going to collapse due to a Carrington event-type shit

if it's enough to turn the moon molten

rather than upsetting the 3/4 of the planet that is ocean

Sooner than anything

then yes, it'd sterilize everything

I mean we don't even know if we have a moon

i can see this room in incapable of entertaining a proto-argument

there's debate on whether or not "the moon" is actually a moon

Nah it's a neat idea actually

@ManAnimal Mercury currently does not have a glass surface

But it would be quite clear from geological strata I'm not sure it is

we have between 0 and 18,000 moons.

to assume that the sun is either always stable or it sterilizes everything is beyond retarded

dawg

lol

i never said 'a glass surface'

Buuuuut yeah there those proposed cycles of the sun
