Universe

[john26]

Stumbled across a question that I can never shake off my mind because I still don't understand it no matter how much info I read:

Given that nothing can travel faster than light, estimate the size of the universe.

Please help me learn.

How do you not understand it?

Light travels, to the best of our knowledge, at a predetermined speed. The universe is, again to the best of our knowledge, infinite.

There is no way to estimate the size of the universe.

We know basically nothing of our universe. Hell, what we know of our galaxy is nothing. What we know of Earth is a smidgen.

3.7 kilometers.

Stop using measurements nobody understands. What is that, like a billion billion miles?

No! Spluh!

It's 800 furlongs, 9 rods and a gallon.

Anyway, what Benji said was correct, and also what Eric Idle sang in the first line of the song was also correct.

"The universe itself keeps on expanding and expanding."

So there you go, it just grew a bit. And it will continue to.


Now let's bring on the creationists!!!

[shadowgrin]

the imperial system is a tool of the devil and that the metric system must be imposed on everyone if they don't want to be accused of being a pedophile nazi sympathizer

[JaoSming]

yea but you could estimate if you know the speed of light and how old the universe is estimated to be (assuming youve gone over this in class)

so 299,792,458 m/s * 14 billion years
299,792,458 m/s * 4.415 x 10^17 seconds
=
1.32 x 10^26 meters

or 1.32 x 10^23 KM dun dum dun dun dun duuuummm

13,200,000,000,000,000,000,000,000 Kilometers


wait....I just did that at 7am after maybe 4 hours of sleep.....the fuck is wrong with me

[benji]

But, you're assuming the universe grew and grows at the speed of light. (As is the OP, despite no evidence for this.)

If you believe big bang and string theories then it doesn't, especially since it grew exponentially at the start and is dependent on the membranes of other universes slapping together at the same rate. That's what she said.

You're also ignoring that the universe began 6,000 years ago when God made it in six days.

Get off my lawn!

We (the rest of the world) really need to do a hostile takeover on the US's indoctrination of the obsolete imperial measurement system.

Leprechaun Universe is OK...if you haven't seen Pirate Universe...

What I don't get is the 'But everything divides by 3 or 4! It's so easy!' argument. Because everything dividing by 10 is so much more complicated.

Nine planets?

[Oznogrd]

its from a cartoon circa 1993. Pluto wasnt special then, it was a damned planet

[Andrew]

And frankly, it'll always be a planet to me. To say otherwise completely ruins this fine board game.

[benji]

I don't know if you guys remember all the Planet X hype in the 1990s, but that was the middle of the stuff that led to Pluto's getting kicked out. Since the 1970s astronomers couldn't figure out stuff out there (especially how it orbits for example) and if they kept Pluto as a planet had to accept all this other junk as planets based on how their classification system worked. So they altered it to kick out Pluto instead of us now having like 15 planets.

To be fair, Pluto was only added as a planet in the 1930s, the others had been so since at least the mid-1800s. (When Neptune got invited.)

EDIT: Animaniacs is kinda underrated. It's better and endlessly more funny than Tiny Toon's. Both have shockingly good video games.

I remember that stuff with Planet X. Also, I must admit I never watched too much of Animaniacs back in the day, nor Pinky and the Brain for that matter but looking back I'd agree they were kind of underrated.

Doug didnt watch very many episodes, he's not even close to naughtiest moments if he missed the line from the movie "even my nuts are frozen"

[Andrew]

Maybe he felt that one was too obvious, not as clever or just didn't enjoy it as much as the ones that made his top 11.

i like this explanation, it matches a formula - thank you

[shadowgrin]

Animaniacs was good but Pinky and the Brain was great.
