Major astrophysics discovery to be revealed

Scientists have promised a groundbreaking announcement pertaining to the birth of the universe.
Speculation is rife that a US team of physicists has detected signs of "primordial gravitational waves", an echo of the moment the universe came in to existence some 14 billion years ago. If this turns out to be the case then it will be one of the most important discoveries in physics for years.

Specific details of what the team has found are expected to be revealed by the Harvard-Smithsonian Center for Astrophysics on Monday.

"It's been called the Holy Grail of cosmology," said cosmologist Hiranya Peiris. "It would be a real major, major, major discovery."

I am a total non-expert on the subject of the cosmos. But does this basically confirm the BBT Or just lend evidence to that end? In other words, are we starring at the smoking gun or what? I hate saying this, but is the BBT Now a law or are we not yet at that point? The Big Bang Theory will never be a law, it will always be a theory. Scientists do not use "theory" in the way that non-scientists do. In science a theory is defined as: A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method, and repeatedly confirme...

The Big Bang Theory will never be a law, it will always be a theory. Scientists do not use "theory" in the way that non-scientists do. In science a theory is defined as: Source: wikipedia In other words a theory in science is something which is generally accepted to be true. A law is also accepted to be true but is slightly different: Source: wikipedia What non-scientist think of as "theory" is what scientists call a hypothesis: Source: wikipedia Good Stuff! Thanks! Such an amazing "discovery" though!

That's really cool! I'm also loving that picture.

I finally manages to get on there, so here is the actually release from the CfA. Have patience though, the site is awfully busy at the moment and it may take a while for it to load: First Direct Evidence of Cosmic Inflation Yup...that's what I thought .

Graviational waves can originate from many sources in the universe and i am not sure how and why do astronomers link this finding with The Big Bang theory? I mean, neutron stars orbiting each other can create strong gravitational waves and who knows, maybe they did detect something similar.

These guys did not directly detect gravitational waves. They detected changes in the polarization of the cosmic microwave background. These changes are consistent with predictions of what would happen if space filled with "hot" electromagnetic radiation and "strong" gravitational waves suddenly expanded spontaneously and extremely rapidly: the electromagnetic radiation rapidly "cools" and the gravitational waves rapidly "weaken" (both consequences of conservation of energy: as the volume increases the energy density of both must decrease). The cosmic microwave background (CMB) that we see toda... [More]

Thanks for explanation. We have to wait more research on this but with more and more discoveries i just get feeling that we need a major change in our understanding of the Universe to actually figure out if similar discoveries are linked to the Big Bang theory at all. All of this could be just 'small' local phenomena of relatively small areas of space. Personally, i doubt the Big Bang theory since i started learning about it and with time i started to hate it. So many flaws since it became a theory and it still have a lot of them. To be honest your guess is probably as good as theirs.

Sheesh I wish I were younger; so much is just over the horizon.

To be honest your guess is probably as good as theirs. No way to confirm anything for now So basicaly anyone could have his theory and i do base mine on the possibility that the universe is vaster place then its accepted right now, with possibly many more interesting phenomena and things that we cant observe while the effects of this unknown 'stuff' might be a reason that we assume that there was, the Big Bang. Hopefully in near future there will be a lot more information, i am kinda sad that its been long time without news or some new interesting theory aobut Dark Matter and Dark Energy. If a... [More]
