My understanding is that NOW we have a new way to weakly measure huge cosmic events. I mean yes -true- this new type of measurement only works upon the results of massive stellar events, like neutron star-vs-neutron star, or black hole-vs-Jeff, yet... overall it DOES confirm what Einstein theorised a long time ago.

Also-- it seems that gravitational waves pass right through anything (unlike electromagnetic waves) without disturbing intermediate material in the least. By comparison, a gamma wave burst by a quasar or whatnot could easily wipe our arses off the Earth, for example.

:applause:

that gives us a whole new look at the universe

[Patrick Chewing]

Shit I will never understand.

OP you should take a trip to the Middle East and spread the news :cheers:

Couple of months too late, now is trending everywhere :roll:

same here TBH.

i think maybe this will help us with dark matter and dark energy-- i.e. why galaxies stick together, but also, why we are flying apart faster and faster.

it was a rumor and now it's officially announced, that's not 'too late'

[Im Still Ballin]

What sci fi movie is this

[FKAri]

Couple of months too late, now is trending everywhere :roll:

It was rumored for months but the official announcement came this morning.

Ming boggling numbers:
[LIST]
The black holes' collision released 5000 supernovae worth of energy in gravitational waves
This energy was generated in less than 200 milliseconds
Peak power output was 3.6

it was a rumor and now it's officially announced, that's not 'too late'
It was a very solid rumor back then, but thing that bothers is that none of the mainstream paid any attention to it, they were more concerned with the Kardashians

Because more powerful gravitational waves were being generated by Kim Kardashian's ass

waiting until everything is certain and official is the right thing to do

[Im Still Ballin]

arguing over this one lads

the movie came out today but they finished filming earlier

what came first

the chicken or the egg

yahtzee

So, you agree Bruce Jenner is more important than a rumor of a scientific breakthrough?

Shit I will never understand.

It's like if you drop a ball on a giant piece of rubber, and it stretches. You can't really tell if the space gets stretched out if you have other objects on that giant piece of rubber (cuz it also gets stretched out). You could tell through light tho. It'll take light a bit longer to reach one object to another if the space between is stretched further apart.

The gravitational waves creates a ripple of space and time. Not only does it strengthen/further confirms Einstein's theory of relativity, we can possible observe the universe and how the Universe is shaped by mass.

Question (on a separate issue):

Ive always suspected that Dark Energy is not so much a 'force' but simply a continuously decreasing lack of concentrated gravitational pull. As the universe expands, matter is less concentrated and thus the inward pull on its expansion weakens, and the expansion speeds up.

Conversely, I believe dark matter IS a cosmic force, just like the forces that bind atomic particles, and not simply some kind of invisible matter.

Your thoughts?

They've already taken that into account for dark energy. Also, I can't say anything beyond that because I don't know the latest evidence and am not an astrophysicist. Neither are you.

Well, matter itself has a gravitational pull. The motion of stars are because of the gravitational forces of matter. The reason why we know there is dark matter out there is because when astronomers add up all the visible matter, it's not enough to explain the motion of stars. So, in a way it is a cosmic force in that sense. But we don't know that much about it.

I remember listening to Star Talk radio and there was a question that asked if we could observe dark matter through Higgs Boson, which gives mass to particles. It is something that we just don't know yet from what I read.

I don't know about Dark Energy. I mean, the universe itself was once concentrated into a smaller space. And the universe is accelerating. Expanding faster than in the past. It is something to look up.

until one day... the big rip! (https://en.wikipedia.org/wiki/Big_Rip)


so what field are you in, micku?
