My four year old just asked a science question which has totally stumped me - admittedly not exactly hard to do that.
Anyway, he knows that daylight happens because of the sun. Even I know that. But why is space black? If the earth can get light from the sun why is space still dark?
Hope I’ve explained that properly. Thanks. |  | | |  |

They forgot to factor in magic, so it's a pretty flawed study tbh |  |

I think it’s to do with the atmosphere in space and space essentially being a vacuum. |  |

is that where the scientific notion if a Dyson sphere comes from? | |

gets worse, one day you'll have to explain Ipswich Town FC |
I’m not looking forward to that day. But it’s coming. | | | |

The concept of a Dyson sphere comes from the early 1900's but was popularised by Freedman Dyson.
Nowadays it's actually seen as a waste of resources, better to have a Dyson swarm as you get the same benefits without the same resource requirements.
Not a Dyson hoover though, you wouldn't want to support a Brexiteer who runs off as soon as possible. Get a Shark, much better name anyway.

Happened to me 15 odd years ago when my 10 year old nephew looked up at me (4 down at HT vs Oldham I think) and said.
"Uncle Lagos, why do we support Ipswich again?" |  |

That's a funny way of spelling Henry.
Our Henry is fab, can't beat it. | |

I learnt about Dyson spheres from a Star Trek episode!!
I agree about the Shark vacuum unless its a hand held one and your daughter start singing
Its a baby Shark na na nananana na etc etc etc ....... | |

I do like a Henry and used to have one but it's such a faff with the leads. Rechargeable cordless is the way forward.
I've just seen they do a cordless Henry now which is rather marvellous.

Still one of my favourite pictures to this day. It's all sorts of right and wrong together.

Exactly. It's Father Christmas. |
Actually, ever since identifying as non-binary it’s Pare Christmas (pronoun: they/them). Pare being short for Parent. To try and force them into a binary identity is a breach of their human rights. The beard has stayed though so they they can associate with both men and women when they visit Wales.

How is it that in space, despite the Sun's presence, the surroundings look black? Apollo photos show a black sky, even with strong sunlight on the surface.
The Moon owes its black sky to not having an atmosphere that can scatter photons. The sky is so dark that an astronaut hiding from sunlight in a shadow would be able to see the stars.
NASA
The answer to this question can be summed up in two words: no atmosphere.
Planetary atmospheres cause bright light to scatter. Atoms, molecules, and dust interact with photons, causing them to diffuse through increasingly dense layers as they near a body’s surface. On Earth, our atmosphere preferentially scatters blue light, so the daytime sky appears blue. And although Mars has an atmosphere that is some 100 times thinner than our planet’s, there’s still enough of it to cause the sky to appear a deep grayish blue, and if martian dust is whipped up by the tenuous surface winds, the sky turns a salmon pink.
On the Moon, there is no atmosphere, so there’s nothing to scatter photons, even from a brilliant source like the Sun. In fact, if you could find a deep enough shadow that shields your eyes from direct sunlight as well as light reflected off the surrounding terrain, you’d be able to see the stars!
There’s another factor that plays into images taken by the Apollo astronauts from the Moon’s surface, and that is the limited dynamic range of the film used to record their surface activities. The sunlight is so overwhelmingly bright that, in order to record highlights, the shadows and sky had to be heavily underexposed
According to astronomy.com |
What about the Cobbold Stand - is it quite dark there? |  |

I think it is fairly widely accepted that the Universe is not infinite.
As for the question about darkness in space. Light travels through space but can only be seen when it hits matter and reflects off it or seen directly from the light source. Since there is no matter in space, it is not visible. |  |

Gauging your leg is quite tricky.
Depends what sort of gauge you use. |
I've got a Mitutoyo caliper he can borrow. Or should that be "I have"?  |  | | |

I believe it is due to there being no matter in space for light to reflect of off (beyond the rocks and ice/gas/rock particles. Of course, Nebula and planets have matter, and out atmosphere is as much a part of why we have daylight as the sun itself. |  |

It's to stop the sun being used up too quick lighting places where no one is
A bit like the security lights that only light up when there is movement
Use that and hopefully your lad will think you are an idiot and won't bother to ask you any more tricky questions | | | |
