Galaxy SDSSJ1506+54 Uses All Its Fuel To Make New Stars, Leaving No Waste Behind
32 replies, posted
[quote]A newly found faraway galaxy called SDSSJ1506+54 is the most efficient star maker ever seen, using up almost all of the gas available to it. Other galaxies are more profligate with their gas, only using some of it and leaving the rest just lying there.

WOW, I don't know why I expected this to be about Samsung...

Their hardware naming scheme kinda looks like SDSSJ1506

really shows you the power of branding that they can do that with a word
But what does this mean? Why is that star grabbing more gas than a normal star?
At a first glance I thought it was a weird equation that when solved gives you "4" and therefore the article was about the new Galaxy IV
Goddamn. It always amazes me how they find shit like this. Somewhere out there there's something even more incredible waiting to be discovered.

It's a galaxy.
The dominant species of that galaxy must be really into recycling.
It doesn't actually use it's gasses to create stars.
The aliens are using advanced tech to suck all of the gasses out of that galaxy and are compressing them into gigantic ships that have so many lights they look like stars.

Prepare for imminent attack in 30,000 light years.

But its 6 billion light years away meaning it already happened!

maybe they are just using a henry the hoover to clean up properly
cosmic dustpan-and-brushes are so outdated
I thought it was about a Samsung phone, and the OP messes with the name due to the millions of new models coming out.

a light year is a measurement of distance so i'm not really sure of the correlation you're attempting to make
1 light year = 1 year.
Employee of the millennia
so on the cosmic scale of things, its the Toyota Prius of galaxies?
[QUOTE=Map in a box;40396583]1 light year = 1 year.[/QUOTE]
Only if they are traveling at a speed close to the speed of light.
[QUOTE=Map in a box;40396583]1 light year = 1 year.[/QUOTE]
No, you can't equate a distance to time.
1 mile = 1 minute
See? Doesn't make sense.
1 light year = approx. the distance light travels in 1 year.

I think your science is broken
[QUOTE=kobalt;40413609]1 light year = approx. the distance light travels in 1 year.[/QUOTE]
1 light year = [i]exactly[/i] the distance light travels in one year
Ughh.
A light year is the distance that light will travel in one year.
Speed of light is constant, at (exactly) 299792458 m/s
One (Julian) year is 365.25 days, where one day is 86 400 seconds each.
So, seconds per year = 31 557 600
Ly=299792458 m/s * 31 557 600 s = 9 460 730 472 580 800 m
There's no way you can go "approximately" on these things when you have a definition on it.
And for you kids that talk about how many years it is between stuff, who cares how long time light will use to go between us? We can't travel at the speed of light anyways.

But the speed varies based on the substance light is travelling through!
[QUOTE=JoonazL;40417472]But the speed varies based on the substance light is travelling through![/QUOTE]
Interstellar medium [I]tends[/I] to be a near-perfect vacuum, so the constant is pretty close to the actual value (maybe fractions off if there's dust or something). The speed would only really change if the light were to pass through a nebula, for example.

Here's the thing.
When traveling at the speed of light, dust doesn't slow you down via friction or impact.
It vaporizes you into more of itself.
[QUOTE=JoonazL;40417472]But the speed varies based on the substance light is travelling through![/QUOTE]
only the phase velocity, light still goes at the same speed, it just has to make more stops

No, but, theoretically we can travel at almost the speed of light.

I wasn't talking about sending myself or anyone else through space at the speed of light, just explaining the slight variances in light's velocity depending on the medium it's travelling through.
but thermodynamics
