about the origin of photosynthesis.

I think there is something there.

if we look at the visible spectra of the sun,

green and red are its largest components.

the protective pigments in leaves that reflect this red light (carotenoids) become visible when the chlorophil dies in the fall.

suspiciously, chlorophil reflects the remaining green part of the spectra almost perfectly

it could be the chlorophylls evolved from one of these pigments.

thats really neat

this is true. I worded my answer poorly.

the sun would irradiate anything alive on the surface while high energy particles whittled away at the ozone, making it worse.

​

NOT TO MENTION, you are absolutely right with venus. it has gravty on its side, there

if we had a weaker pull, like mars, then in that case i think it would erode the atmosphere completely

I'll direct you to look at the MAVEN discoveries, to verify me there

this is something i feel is missing from the explaination.

without our magnetic field, genetic life couldnt exist in the radiation produced by our star.... and even our atmosphere woule be eroded away by solar wind

​

there is a HUGE difference between a 'dead' core and 'active' core world.

one has an atmosphere, magneticfield, and life.

the other, all things being equal, does not

I wonder why you didnt mention a heat generating core vs a 'dead' core in terms of the magnetic field, the atmosphere, and the star we orbit around

just a squirrel, doing it's part to protect humanities infrastructure from snow and ice!

why does it have to come from anywhere?

okay...maybe it'd be simpler to explain it mathematically.

it's like the coordinate system is changing so there are more points, all the time.

there are more grid squares every time we look.

Itself. It's not expanding into anything there's just more of it all the time.

There's nothing outside of the universe.

If there was we would need to change our definition of universe.

The Big bang wasn't an explosion in space it was an explosion of space.
