But if you think about it...we shouldnt really have pitch black nights

OK if it was a serious question then the serious answer is that we don't have pitch black nights.

Light pollution blocking the stars.

but if the sunlight reaches all the way past earth shouldnt we have still have light...and also the reflection of shit in the atmosphere space starlight etc...

sorry my mate bought around his new girlfriend last night we all got drunk she started asking these stupid questions ....


I googled it and got some olbers paradox shit....

Yes, when you can see planets through telescopes that's the light from the sun being reflected off of them. But there needs to be something there to reflect light. Space is called space because it's largely just space.

 

[BIG MATTY WHITE]

You can get some excellent telescopes for around 2-3k that have attachments for SLR cameras that can take some pretty interesting photos. However they will mostly just return a blurry picture of Jupiter but you can make out features of the planet. Saturns rings for example are quite pronounced even with basic telescopes.

Really cool shot of the international space station with jupiter during daylight hours:

I always wanted to get a scope...maybe when I am older...

but i guess my question is more how does 1 see jupiter how does 1 discover jupiter how do you take a picture of jupiter if it is made of a colourless transparent gas...

I could understand that gravitational pull could lead to a discovery but photos etc

This is exactly what I thought too but then there are so many stars in pretty much every direction you look it shouldnt be any darkness

Because the gas is neither colourless nor transparent

Jupiter is visible to the naked eye.

That would only make sense if the universe was infinite and/or had an infinite number of stars.

Yeah but the distance from earth to even the closest star is so mindboggling huge... so the light gets diffused.

On your other post, Jupiter isn't made of transparent colourless gas.. the gas has colour because it's under extreme pressure-due to gravity.. or some such.

I dunno. I didn't pay attention in science class either and that was nearly 30 years ago...

thats the thing scientist say it is infinate some say it isnt

I had look on google it comes under orbas paradox who was the first scientist to question darkness at night but no one really has come up with an agreed answer...

some say that the light hasnt fully reached earth yet from the stars some say pockets of gas in space block the light from reaching us

The lights just taking its time to get here

jupiter and uranus I believe is made of hydrogen and helium right down to the core which are both colourless and transparent if you say that it gains a spectrum because of gravity well I dont see how but I guess it plausible

 

[raman]

No they don't.

 

[Jim Dixon]

Olbers paradox

I don't understand this to be honest. I fail.

 

[BIG MATTY WHITE]

Yeah thats probably the best answer but scientist cant agree on it

 

[Jim Dixon]

No, there's ammonia and all sorts of other stuff in there as well.

 

[BIG MATTY WHITE]

No they don't.

They arent sure whether its infinate or not..not

I am pretty sure some say its expanding

 

[BIG MATTY WHITE]

No, there's ammonia and all sorts of other stuff in there as well.

dont quote me on this but 90% hydrogen the rest of the 10% is mainly hellium

 

[It Just Is]

Olbers paradox

I don't understand this to be honest. I fail.

More specifically, because the universe is finitely old and the speed of light is finite, only finitely many stars can be observed within a given volume of space visible from Earth. The density of stars within this finite volume is sufficiently low that any line of sight from Earth is unlikely to reach a star.

This paradox is explained by the fact that the Big Bang theory also involves the expansion of space which can cause the energy of emitted light to be reduced via redshift

 

[BIG MATTY WHITE]

I read that too it just is then i read that the universe is expanding and is infinate...so scientist cant agree

 

[BIG MATTY WHITE]

Also the big bang is not proven

 

[raman]

dont quote me on this but 90% hydrogen the rest of the 10% is mainly hellium

That describes the large part of the composition, yes. There are still countless other elements. The clouds visible on the surface are thought to be composed of sulfur or phosphorous.

 

[raman]

Also the big bang is not proven

It's also not bettered.

It might be counter-intuitive, but science doesn't actually work by trying to prove things. It works by proposing falsifiable models, and then trying to disprove them.

 

[BIG MATTY WHITE]

Its not bettered is only an opinion... it holds as much scientific weight as any religion or aliens brought us here...

it does my head in but thanks raman the discussion and for the plausible answers

 

[BIG MATTY WHITE]

There were many more stupid questions too

like why wasnt pompeii in the history of the romans
And whh nevermind crazy stuff...

Some of the more pricey telescopes comes with software in which you hook your laptop up to the scope, and it will get the GPS location you are at, and then it will adjust the telescope to the locations of any given planet etc for viewing. It's really great stuff. In terms of actually seeing Jupiter, it would be due to the light from the sun passing through the gasses giving them luminescence. Similarly to how water spray shines in the sun here on earth.
