similarly you can have 10 coat-hangers/stick-insects playing effortlessly with you... sticks gone wild !!
No S/M pls, tnx!

No scientist will tell you he has the absolute truth, what they will tell you is, it is highly likely or what does not work, this experiment seems to have backed up earlier theoretical data, does it mean it is absolutely certain, well we can say it is highly probable.
It started with a bang, and has been expanding ever since. For nearly a century, this has been the standard view of the Universe. Now one cosmologist is proposing a radically different interpretation of events — in which the Universe is not expanding at all.
In a paper posted on the arXiv preprint server1, Christof Wetterich, a theoretical physicist at the University of Heidelberg in Germany, has devised a different cosmology in which the Universe is not expanding but the mass of everything has been increasing. Such an interpretation could help physicists to understand problematic issues such as the so-called singularity present at the Big Bang, he says.
In the space around us, on Earth, in the Solar System and our Milky Way Galaxy, as similar objects get farther away, they look fainter and smaller. Their surface brightness, that is the brightness per unit area, remains constant.
In contrast, the Big Bang theory tells us that in an expanding Universe objects actually should appear fainter but bigger. Thus in this theory, the surface brightness decreases with the distance. In addition, the light is stretched as the Universe expanded, further dimming the light.
So in an expanding Universe the most distant galaxies should have hundreds of times dimmer surface brightness than similar nearby galaxies, making them actually undetectable with present-day telescopes.
But that is not what observations show, as demonstrated by this new study published in the International Journal of Modern Physics D.
The scientists carefully compared the size and brightness of about a thousand nearby and extremely distant galaxies. They chose the most luminous spiral galaxies for comparisons, matching the average luminosity of the near and far samples.
Contrary to the prediction of the Big Bang theory, they found that the surface brightnesses of the near and far galaxies are identical.
These results are consistent with what would be expected from ordinary geometry if the Universe was not expanding, and are in contradiction with the drastic dimming of surface brightness predicted by the expanding Universe hypothesis.
“Of course, you can hypothesize that galaxies were much smaller, and thus had hundreds of times greater intrinsic surface brightness in the past, and that, just by coincidence, the Big Bang dimming exactly cancels that greater brightness at all distances to produce the illusion of a constant brightness, but that would be a very big coincidence,” Mr Lerner said.
That was not the only startling result of their research. In order to apply the surface brightness test, first proposed in 1930 by physicist Richard C. Tolman, the team had to determine the actual luminosity of the galaxies, so as to match near and far galaxies.
To do that, the astrophysicists had to link the distance to the galaxies with their redshift. They hypothesized that the distance is proportional to the redshift at all distances, as is well verified to be the case in the nearby Universe.
They checked this relation between redshift and distance with the data on supernova brightness that has been used to measure the hypothesized accelerated expansion of the Universe.
“It is amazing that the predictions of this simple formula are as good as the predictions of the expanding Universe theory, which include complex corrections for hypothetical dark matter and dark energy,” said study co-author Dr Renato Falomo of the Osservatorio Astronomico di Padova, Italy.
Dr Riccardo Scarpa from the Instituto de Astrofısica de Canarias, Spain, who is a co-author of the study, added: “again you could take this to be merely coincidental, but it would be a second big coincidence.”
Therefore if the Universe is not expanding, the redshift of light with increasing distance must be caused by some other phenomena – something that happens to the light itself as it travels through space.
“We are not speculating now as to what could cause the redshift of light,” Mr Lerner said.
”However, such a redshift, which is not associated with expansion, could be observed with suitable spacecraft within our own Solar System in the future.”
Now come on he is not under any obligation to embrace socialism or that of the kind which the North Koreans supposedly practice LOL ,anyway I love cats my self, by the way you need to look up the doppler effect.kudos@Levina @Zibago @Mentee
yes, life is too short for breeding all kinds of unnatural hatred within ourselves... i am a simple and gentle person, much like the cats i have lived with for years... there is no need for apology from him but the necessary requirement is that he quit his arrogance that is based on fallacy and that he accept socialism, for this will ensure that he remains humane... this is a simple ask... a cat gets confused and sad when those he/she knows behave in a cruel manner... same with me.

Steps of scientific methodNo scientist will tell you he has the absolute truth, what they will tell you is, it is highly likely or what does not work, this experiment seems to have backed up earlier theoretical data, does it mean it is absolutely certain, well we can say it is highly probable.
@jamahir and @Nilgiri guys lets bury the hatchet as life is too short.kudos
@Levina @Zibago @Mentee
yes, any true scientist will be of a gently doubting and discovery-seeking disposition... but the fellow in the vid and so many members on this thread are priests, full of fanatical belief in what may not exist at all... they are patting each others' backs while making post upon post in laughing at my simple questions and deriding them without themselves being the god who if exists must have created the universe and thus knows the steps.
one constant theme among members here has been "universe is expanding"... but some physicists have rejected it in recent.

ghanta i will respect the arrogance of some members here !!

educational institutions have become more like churches and masjids, no matter what wont appreciate constructive intellectual thinking, just make a copy cat out of you----- folow,obey, and bear------- they have been making us run in balck n white areas--- in their dictionery the word grey, does not exist
kisi ko ph*** lganay ka assan tareen raasta------ yar iam not speaking of my self the scientists have said that
and as for the shabd ghanta you can replace that with baba g ka -------- koe sunnay ko tyaar he nae hain as you have committed a scientific blasphemy
that's right... "baba ji ka..." is sometimes more effective than ghanta.
yes, i have blasphemed... zombies, zombies some of them here, lynching and stoning those who don't agree with the assertions of their beloved phd's and institutions.
i am the zandiq in their confident beliefs.
Its not about mocking you Jamahir.@Levina @Zibago @Mentee

the experiment u r refering to was a fial and was caused by a faulty element of the experiment's fibre optic timing system. And the faster then light theory was proved wrong and Einstein right. again.
Ridiculous: A Loose Cable Caused Those 'Faster-Than-Light' Particles
If u checked my thread:@500 @ayesha.a @LeGenD @FairAndUnbiased @Schutz - your opinion on the above two articles??

i don't understand your behavior... you are one thing in the female-appreciation threads but are insulting to me in other threads.
@Zibago @django @MaarKhoor - please note the duplicity and crudery of nilgiri's behavior... do you think he can be a real friend??
If u checked my thread:
Common misconceptions about atronomy
I wrote there that Bing Bang is not a fact but theory still. Same goes about Dark energy, Dark matter and even black holes. But its best theory we have now. All other theories are much more complex and have more problems.
As for Special and General Relativistic theories, they were proven in uncounted experiments and calculations and so far not a single experiment showed its wrong. We clearly see time slowed with speed and gravity (and this is used in GPS), we clearly see light bending because of gravity. We count orbits of planets with it (for example Mercury). More over we proved that gravitation wave exists before that, but we just did not register 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??
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??
and we must of course bow to them without question and we must obey.
