Well, for one, the gravitational wave detector was operational for a decade at a lower power state and was tuned to rule out seismic activity from the beginning. They know what seismic activity looks like. Seismic activity is billions of times stronger than what they are even looking for so there is absolutely no way the two can be confused.How do we know fornsure that this distance is created by gravitational waves? Isn't it possible it could be seismic activity, you know, a train going by a few miles away, or some other phenomenon?
You know, I enjoyed the video, I just can't stand Colbert.
Stopped as soon as I heard him saying "Idiot scientists seeking more funding".... But OMG I have a youtube channel and here's a video why
Yup, he old characters was basically a mockery of all the hardcore conservative pundits on Fox et.al., and there was brilliance in that, of course if you are a hardcore conservative person then you probably didn't find his brand of comedy funny. That said at the end of the day 99% of it is what writers write, and how to act the character that they make. Most comedians aren't inherently funny, it's other people who are the funny ones the comedian is simply the person who gets credit for the laughs, however in a live format you need to have some quick wit as well and have the ability to go off script/work around your guests, otherwise you do sound like a dead comic.He's toned his thing down a lot since the Colbert Report to appeal to a broader audience, and in the process I feel he has lost something. While he was only funny to a certain subgroup of the population before, now I feel he just isn't that funny at all anymore. Occasionally he'll get a smirk out of me, but that's about it.
It's almost as if he toned down his previous style, and merged his new lower intensity style with that of Letterman, and the result is less fun.
There are 2 LIGO detectors in different parts of the country. Using triangulation, it can figure out where the source of the signal is coming from. The source of the gravity waves came from 2 black holes in the process of merging. It's true that the effect is small: less than the width of an atomic nucleus (so measuring it with the I in LIGO is important). The signal is periodic, and not the result of "an earthquake" or other random effect. The measured waves matched theoretical predictions: an explanation wasn't simply plucked from an observation. First observation of gravitational waves - Wikipedia, the free encyclopediaThe downside is, what celestial objects are you actually picking up waves from?
Without multiple detectors its not easy to determine direction and the signal is so weak.
Probability has to figure highly.
ps not watched video, not easy where I am.
Hey, you said something that's absolutely true. There is no possible way that radiation from a solar flare can get inside a sealed tube to affect laser light!There is no possible way radiation from a solar flare could interfere with our light based laser experiment! !
I registered just because I'm getting annoyed with how non critical and dogmatic "science" has become lately, and post some links to alternative explanations for the findings. But now I cannot post links.
