Einstein's Messengers

Ripples in the fabric of space-time from monumental collisions between black holes, and how scientists are trying to measure them with lasers and mirrors. From LIGO and the National Science Foundation.

@20fireman12 How do you think they wudd be able to take all this mats requied for this Ligo building all the long way up to space?

[locast]

build it on the moon!, no waves no trucks no baby crying

[20fireman12]

wouldnt it be better to have this as a satellite so the earths gravity doesnt effect the "G waves"?

Also Ligo has failed to find anything in the 5+ years it was created

[willzjc]

aether testing all over again

I'm going to try to explain a little better. BB says a portion of the singularity began to expand, caused by a quantum fluctuation. Where did the singularity come from? How long was it there before expansion? How can this expansion of already existing material be called the "birth" of the universe? What about the singularity? It didn't exist? The BB is no beginning at all. Why do all the #'s at the singularity go INFINITE? Check Guth's inflation model: It predicts infinite BBs.

@2eelShmeal I probably shouldn't reply to you, as you seem to be obsessed with the unclear messages you try to preach, but I never denied the facts you have managed to put in between your rest of made-up statements.

You are the one who should study more because you clearly do not know what those scientists are trying to tell, if you say what you say.

It is obvious that nobody will witness the big bang directly, so we ale left with our reasoning about the consequences.

@ZdenekJindra What I'm referring to is the fact that the BB theory requires starting material. The singularity. Where did it come from? How long was it there? How could there be no time if something exists? (The singularity) The scientists make no claim as to where the singularity came from. And FYI, NO SCIENTIST KNOWS IF THE UNIVERSE HAD A BEGINNING OF IF IT IS FINITE OR INFINITE IN SIZE. So don't tell me about science. Evidence and thinking... Yeah, you need to provide some and do some.

[ZdenekJindra]

@2eelShmeal Evidence and thinking. But you considering that it may be wrong is actually a display of them previously admitting that it may be otherwise. If science made dogmas, you wouldn't be asking questions now.

Competing theories are being constantly pursued and if any of them starts making more sense than the current one, it will eventually make it to the media where you will hear it. Scientists are actually a bit smarter than portrayed.

What makes these guys so sure there ever WAS a beginning to space and time?... Assumption after assumption....
