I was reading in some of the papers...can't remember which, but they believe that the CC was acting much like a form of gravity, except in the anti sense. Probably not strictly correct, though.
Remember, mass and energy are interchangeable and in the conditions that occurred in the early Universe, that energy would've had extremely high density. That alone, would've produced gravitational effects as the energy would've essentially been massive....i.e. acted as mass would.
It would mean that photons and whatever else that was around at the time that constituted the energy budget of the Universe must've been interacting with the Higgs field in some fashion, or maybe under such extreme conditions Higgs bosons act much like photons. Don't ask me how, I'm not Stephen Hawking!!!!. It would mean that the Higgs Field must've come into existence either prior to inflation (maybe when gravity froze out) or during inflation. Now, what they have to do is find the Higgs. Anyway, enough of the conjecture |
Energy on its own won't contribute to gravitational waves. Energy converted to mass or vice versa will.
And here lies the problem......
If such an event occurred in the Inflation era we would not be able to measure it as gravitational waves do not exceed the speed of light.
The event is beyond the observable (measurement horizon) of the Universe and will remain so due to the acceleration of space time.
Looking for gravitational waves in the CMB is taking us back to the recombination era about 300,000 years after the end of the inflation era.
Perhaps the article is confusing the CMB as being a product of inflation.
