Gravitational waves announcement: Scientists confirm detection of ripples in spacetime

[jamahir]

That is what has been proved...the physical presence of such waves in the universe and that these waves carry a lot of info in them.

proved when?? by who?? how?? how come they have not been employed in space-craft propulsion in space or recreated or amplified for earthly vehicle anti-gravity propulsion??

Big Bang is not a one-time event but an ongoing process.

a simple set questions or points : so according to our phd'ed astronomers, the universe's elements ( galaxies, worlds, stars etc ) are flying away hither-thither from their place of creation or coalescing... flying away to somewhere, and somehow without interference and collisions... so the entire sol solar system is flying away in one piece... what about the extremeties of the universe?? where will the elements go?? will they dash against a wall?? in fact, what are the extremeties of the universe??

for the sake of "democratic "liberal", terndy and "just" values,yes

and we must of course bow to them without question and we must obey.

at the moment i can't think of one, but given time i could find... but my point is these mathematicians in guise of astronomers have not provided one simple-to-understand cosmological or experimental observation to support their claim of existence of "space-time" and possibility of time-travel.

perhaps, quantum physics could prove that

i did not get this part.
what have not been employed?

i didn't think about that---are we going to collide----

the waves--

I agree with you on time travel yet in regards too space-time how can something grow from Plank size to the amazing 28 billion parsecs. Space-time as manifold is something that can exist .grow and morph, the question arises how can space expand if space-time has not some fabric like concept to it.

quantum physics is another magical field like "space-time".

what have not been employed?

we know that light exists and light can be employed, whether for projecting images ( cinema ) or for cutting up metal ( laser ) or for propelling space-craft ( light sail )... similarly, since you spoke about people having proof of gravitational waves or what the article calls gravitational ripples, i was wondering that just like light can be employed, why couldn't gravitational waves be employed in various things including vehicle propulsion??

or is it that these so-called astronomers simply are preaching mathematics rather than reality??

 

[Levina]

the waves--

oh okay.
@jamahir i get it now.
Lol
The title says waves have only been detected and they are yet to be employed for anything.

since you spoke about people having proof of gravitational waves or what the article calls gravitational ripples, i was wondering that just like light can be employed, why couldn't gravitational waves be employed in various things including vehicle propulsion??

come on!
this is just the ANNOUNCEMENT....
the waves, info carried by it and everything will follow.
Patience!

that has not happened in the known anthropological and geological history of this world, despite earth-to-mars space-craft travel taking only seven months to accomplish with typical chemical rockets.

so can those "oh, the universe is flying apart" theories simply be without substance??

isn't it a science?

all i understood is a question raised by you that why we are hell bent on proving the past space events why not prepare for the future, like going to settle on moon n mars, having a cup of tea

by "something" you mean galaxies or stars??

nevertheless, what does such growth have to do with "space-time"??

aren't there "aggregate asteroids" which are loose collection of dust and rocks and pebbles held together by loose gravity?? in time, if there is more material around such a collection, the collection's gravity ( gravity is a unexplained phenomenon ) will attract the surrounding material and will add to the collection and grow it... given thousands of years or a few million years, such a collection will grow into a world and given enough material and time can grow into a star.

so??

and what do you mean by "how can space expand if space-time has not some fabric like concept to it"?? space is largely vacuum with molecular elements and small gases in some places and dust and rocks and stars and large nebular gases and so on.

and what is "morphing"??

It was measured physically.
The arms of interferometers move when they detect certain waves. The measurement is sensitive to within 1/10000 of the width of a proton.
So scientists had to wait for sometime to confirm the news.

i vaguely know about real employment of this field... one i have read here and there is spintronics... another is supposedly non-interceptable optical communication... another is the long-awaited ( like fusion power ) quantum computers.

it all seems a big scam to earn phd's and jobs.

bas khatam. **hands wide and one thrust made, in emphatic agreement**

i see.

okay, someone on pdf should take up the burden of creating a thread explaining in the simplest of words the entire process of this observation from start to finish... no equations must be used and my previous questions about non-employment of "gravitational waves" must be answered... also must be given the proof that this "movement of the arms" happened because of gravity waves rather than light ( "light sail' as control ).

yeah why not...
we are all Einsteins here.
@jamahir its upto you to believe in the existence of these waves. I neither have the knowledge nor time to create such a thread. I told you what i read about the waves, and to me its existence makes sense.

ciao

come on, i didn't mean to irritate you... i was simply trying to bring calm to a thread where people were jumping only because some american government institution made a announcement and which was replicated by jumping jacks in universities elsewhere.
