u guys should go debate it

2019-05-15 16:35:52 UTC  

in civil debate

2019-05-15 16:36:17 UTC  

No its too dumb to debate. Even here

2019-05-15 16:36:28 UTC  

There is a limit where you can see, it's called the observable universe https://en.wikipedia.org/wiki/Observable_universe

2019-05-15 16:37:01 UTC  

There is a point where the photons become so spread out that it's basically impossible to see anything, but that depends entire on the object's luminosity.

2019-05-15 16:37:09 UTC  

Also light takes a certain amount of time to travel a specific distance

2019-05-15 16:37:24 UTC  

Oh, observable universe?

2019-05-15 16:37:30 UTC  

we dont even know how fast light travels in space

2019-05-15 16:37:34 UTC  

I wasn't talking about that.

2019-05-15 16:37:47 UTC  

The observable universe is a spherical region of the Universe comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time, because electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion.

2019-05-15 16:37:48 UTC  

We do. We calculated it

2019-05-15 16:37:51 UTC  

It's about 30,000,000 meters per second

2019-05-15 16:37:57 UTC  

who calculated it

2019-05-15 16:38:03 UTC  

who went to space

2019-05-15 16:38:07 UTC  

Hey stupid

2019-05-15 16:38:12 UTC  

Some random guy not worth researching

2019-05-15 16:38:39 UTC  

@Ivan Pavlovich more like 299,000,000m/s

2019-05-15 16:38:42 UTC  

299 792 458 meters per second

2019-05-15 16:38:55 UTC  

who got that number in space

2019-05-15 16:39:02 UTC  

Light is a wave and waves have a period and wavelengtho therefor it has a speed

2019-05-15 16:39:02 UTC  

who went to space and got that number

2019-05-15 16:39:06 UTC  

Light can also slow to 17 m/s

2019-05-15 16:39:24 UTC  

sheeple after it leaves the cold medium does the light speed back up ?

2019-05-15 16:39:52 UTC  

Yes the wave speed varies depending on factors

2019-05-15 16:39:59 UTC  

@jeremy In the case of quantum tunelling.... light can travel infinitely fast

2019-05-15 16:40:02 UTC  

Light int the void, in another environment the refractive index change but v = c/n so the light speed change

2019-05-15 16:40:08 UTC  

Yes depending in conditions

2019-05-15 16:40:15 UTC  

how does it speed back up after doesnt that violate some rule of physics or something

2019-05-15 16:40:24 UTC  

No

2019-05-15 16:40:28 UTC  

@jeremy how many physics courses have you taken

2019-05-15 16:40:33 UTC  

whats speeding the light back up after it leaves the cold medium

2019-05-15 16:40:40 UTC  

0

2019-05-15 16:40:45 UTC  

Have you read up on Newton's laws?

2019-05-15 16:40:46 UTC  

I dont feel like discussing waves sorry everyone im dipping

2019-05-15 16:40:51 UTC  

Okay well that would explain it

2019-05-15 16:41:00 UTC  

Nothing speeds it back up.

2019-05-15 16:41:05 UTC  

I can see that we're dealing with a professional here, watch out everyone /s

2019-05-15 16:41:30 UTC  

Nothing will speed up unless acted upon by an outside force

2019-05-15 16:41:32 UTC  

light enters a cold medium slows down to 17km per hour it leaves the cold medium goes back to whatever 300km per second
