Why There Is Light on Earth But Not in Space
Вставка
- Опубліковано 26 сер 2024
- If you’re not a morning person, then you’d probably love living on the moon or out in space! The whole “lack of oxygen” thing aside, a ‘round-the-clock night sky sounds pretty tempting! But why is there so much light on Earth, but almost none once you leave our planet?
You might think that it’s light during the day and dark at night because the Earth spins on its axis, and the Sun illuminates either hemisphere. That’s part of the reason, but it’s more complicated than that. Our star shines on the Moon too, but the sky above it is always black!

SUMMARY:
- The atmosphere surrounding our Earth is full of dust, dirt, gases, and water droplets - which all act like tiny mirrors and reflect the sunlight.
- If you find yourself on the Moon, where there’s no atmosphere, the sky will be black. You’ll be able to see the stars even when the sun is blazing on the surface during the lunar day.
- In the early 19th century, German astronomer Wilhelm Olbers suggested that the reason the sky is dark at night was a dusty veil that hid most of the stars from us.
- Thanks to our fancy powerful telescopes, we now know that it takes light billions of years to get to us from the farthest stars.
- Modern telescopes can show us that the light started its journey to the Earth about 10 billion years ago. The more powerful telescopes get, the further back in time we can see.
- But don’t all those distant stars give at least some noticeable light on this planet? It’d be like switching on a ton of tiny halogen light bulbs. They’re not as bright as one big LED bulb, but they do give off part of its light.
- Space might be empty compared to the Earth’s atmosphere, but there are a lot of gases out there. They move around, form clouds, and serve as a sort of veil hiding most of the light in the Milky Way.
- The theory states that the Universe was born in a Big Bang 13.8 billion years ago. Since that time, everything has been moving away from the point where it all began.
- Sources of light also move away and spread out, which means space is getting darker, and the number of black areas is growing.
- Astronomers think that most of the matter in the universe is invisible, and it looks like black emptiness to the human eye.
- If you remember the electromagnetic spectrum from back in school, you’ll know that visible light is just a tiny sliver of all those wavelengths and frequencies.
- Red, blue, purple, yellow, orange - the whole color wheel depending on which gases make them up!

It’s the same rule of florescent lamp since Earth is covered by ozone. The sun heated ozone and so ozone shines typically like the gas inside the florescent lamp.
Guess what Islamic Holy Book Qur’an, by the tongue of unbelievers, refer to the space darkness. In Surah Al-Hijr verse number 14 and 15 :
(And [even] if We opened to them a gate from the heaven and they continued therein to ascend, (14) They would say, "Our eyes have only been dazzled. Rather, we are a people affected by magic. (15)

it's very cool to look in to the night sky and wonder if the stars I see are actually still there. They could have passed on and I am looking in to the past. Sort of like time travel in a way
It is! That's why I love star gazing

@@mzzsoldier25yearsago65 lol
Creation is just what it is...wonderful. 😊
To make a long Bright Side answer short: Space is black because there is nothing for light to illuminate on. The Earth's sky is bright because the atmosphere has gas, and thus something the sun can illuminate on. Space is mostly empty pockets of nothing, and nebulas are bright because they are composed of mostly hydrogen gas, so the nearby stars can shine on something.
The photons that stars produce cannot shine on something in space, making it so dark.

Why is Space Black?
Because that's how the NASA artist paint it!
You know right
All anyone has to do to see what space looks like is purchase a good telescope, and point it towards the heavens. See for yourself. Or do you think NASA painted up there too? I mean, nobody's THAT far gone, are they?

@Joshua Creasey cells? That are made up of hydrogen, oxygen, carbon and nitrogen?
5:28 wen you tryna sleep and someone walk in and turn on yo room light
Lemme save you 8 min with the simplest explanation.
It's because Space is empty space. Light can only be seen when it reflects off of a surface (any kind of matter) or when observed directly from it's source. So light can't be seen on space bc it's almost devoid of matter -hence why it's an empty space- which light would reflect from.
I say "almost devoid" because there's still a very small amount of floating dust particles in space.
I know you are technically right, but I'm having a bit of a hard time accepting that argument. You know these strobe lights they place on top of stadium roofs ? They light up the sky at night and, even without the presence of clouds to reflect incident rays back, vertical twin beams can be seen dancing around each other from miles away without having to see the source itself. Only explanation for that is the presence of dust particles that refract light to the eyes watching it. But if that were the case then we shouldn't have to throw powder in front of a laser pen to see the red beam...what am i missing ?
Thanks
@@MarioCini1 Well you are right light from those strobes is from lasers which is a collimated (concentrated) light, it does not "spread-out" in space hence it has a very high intensity so it can be seen over a distance. Light from stars isn't and its intensity weakens because it "spreads-out" in space , because the distances between stars are so large you only see a weak "spot"(stars). On the laser however, during the day you can't see them because the background light is too bright in which case you use smoke so it scatters the light. Same way you can't see anything else if someone blinds shines their bright headlights in your face, but then you can when they dim them.
So you saying space is nothing.
It is black because I have no money.

Moon what?
Here’s a question for you Brightside. Will light stop traveling if nothing interferes or gets in the way and how far would it travel? And how does it travel through dark matter?
*I'm in love with the narrator! His voice is soothing and relaxing to listen. This video explains better than NASA and BBC.*
honesty i could not agree more
E B He’s no Kermit the frog but he’ll do.
"You'll be able to see stars in the surface of the Moon even when the sun is blazing in the lunar day". Tell that to Armstrong, he forgot.
Armando Balance Armstrong never made it to the moon
That was my very first thought. Neil Armstrong, when asked about the lack of stars, said that they weren't visible due to the glare of the sun on the moon's surface. That would put doubt as to whether they actually landed there.
Their saving grace in that argument is that they did mount a reflector that can bounce laser beams back to Earth that gives accurate measurement of the moon's distance from the Earth.

This title made me think about life as a whole for a while
This all seems so simple when it's being explained, but it's actually harder to understand than you think. We'd all have a much better understanding of space, time, light, gravity, distance etc, if we go out there and experience it for ourselves, nothing really beats experience, we can also know what we know from the scientific research, and keep studying it all though.
The problem with that , like I’ve always had by religions… you’re listening to someone tell you this is that because of that, this is real because some guy told us…. I don’t trust and believe in what I can’t touch or see myself
I've always wondered what's *below* the earth as in under us in space...
More space🤣
There is no "under us" in space.
In a nutshell, space is so vast and so big that the stars in it can't work hard enough to light it up.
Too much area to cover, basically.
Why is it so dark on outer space?

Why its dark in space ?
Coz no light
Imagine if you were in a room you can see the light because the light has something to hit (the walls) while space is yk space so the sun has nothing to hit because it’s not like a wall it’s an end less space. So imagine if your in a room with a light bulb, now imagine the walls are expanding, its gonna be farther the light travels and doesn’t have enough energy to light the whole room. That’s space lol I’m high
Awesome Izac Reyes
@1:10 the Apollo 11 post flight press conference...Neil Armstrong, Buzz Aldrin, said they did not see stars in the surface and Michael Collins also said he did not see any either...
That's because the moon's surface is very brightly lit by the sun and the stars are relatively very dim. Can you see a candle flame in bright sunlight? It's basically the same thing.
@@adolforodolfo6929 the Apollo 11 astronauts had contradicting statements, they said they didn’t see stars on the surface, and in another interview they said they did see stars and they were spectacular on the surface...

@Jordan Mercer I thought the orange thing was Mars 🤔
Stars do glow during the day, but we can't see them because of the glare of sunlight. When the sun is up, the blue color in sunlight gets scattered all over the atmosphere, turning the sky the familiar bright blue color.
Light is actually everywhere! We only observe what hits our eyeballs.
*Answers-*
*In space, No light*
*No light , no colour*
*No colour,black color*
*Hence, in space ,Black color*
light traveled through space to reach earth.
Two points. In addition to scattering sunlight, our atmosphere also filters out some of the parts of the spectrum. This is why we send up satellites to observe gamma rays, x-rays, parts of the ultraviolet spectrum, and infrared.
Second, in terms of the electromagnetic spectrum, from low energy (and longer wavelengths) to high energy (and shorter wavelengths), the proper order is: radio, microwave, infrared, visible light, ultraviolet, x-rays, gamma rays.

It's just my own observation, but if you shine a torch at a wall from say 1 foot, it forms a bright smallish disc, as you move back the disc gets bigger and the light gets dimmer. Surly this explains in part why distant stars don't light up the night sky.
"The science of today is the technology of tomorrow"
Because there’s not much to reflect light.
Saved ya 8:22.
Light is invisible?

JustKeith We see things because they either emit or reflect light. Light, unless passing directly into your eyes, is not visible until it interacts with another object.

"I dont recall seeing stars from the moons surface " Neil Armstrong: so who's right Brightside or Armstrong?
Armstrong because in all pictures from the moon and when looking at earth there is never any stars. I ask this question all the time.. where are the stars?? So too hear that they all said it he is right.
The Moon's surface + the Sun is very bright during the day. Astronauts on the Moon couldn't see stars because their eyes were overwhelmed (= dilated pupils) by the glare. I mean check out how many fewer stars you see in the night sky when there's a full Moon, and that's from the Earth. Imagine you're standing on the Moon - you need sunglasses because of all the reflected light.

Sun: "Hold my rays"

U make Interesting videos it helps me alot in understanding science
I feel more comfortable in darkness than watching this content. UA-cam please stop adding this to search results.
And here I thought it was simply that the number of photons we see from distant stars is fewer because over hundreds, thousands, and millions of light years, the photons spread out wider and wider from their source.
"Why is space dark?"
Because if it is whit the stars wont appear at night:
