The universe is humming with gravitational waves. Here's why scientists are so excited about the discovery

[Admin]

The very fabric of the universe is ringing with gravitational waves from its earliest epoch, and researchers have finally "heard" this cosmic symphony.

Great stuff. But this isn't high school newsletter writing. You can get rid of all the exclamations, IMO:

"... the effect on spacetime as being as small as around one part in 1,000,000,000,000,000!"
"... some neutron stars spinning as fast as 700 times per second!"
" ... just on a whole different scale!"

If it reads fine without exclamation marks, then you don't need them.

crash of the symbols? should be cymbals.

Overstating things a little to say GW were detected; the team is reporting the detection at a 3.5- to 4-sigma level. Promising but not the full monty.

The Universe has sped up to an extreme level, scientists say

The universe went in “extreme slow motion” at its beginning, and has dramatically sped up since, scientists have found.

Decelerator just a little bit slower and it would be an eternally fixed constant of Horizon. Oh, it is a constant of Horizon, as I have it! All it has to do is have the background still farther back become even slower, and slower, and slower, and slower.... toward a frozen, or virtually frozen, photo Horizon constant of picture.

The comedy act, well almost a comedy act, continues.

Instead of thinking of the singularity as a discrete "point" in spacetime, think of the singularity as a gravitational wave in spacetime with no upwards limit to its frequency.
The expansion of the Universe is a natural consequence of a shared origin in a common space, a space which is not finite, but only appears to be due to the natural limits of human observation.
In accordance with the limits of observation, a wave in spacetime of sufficiently high frequency would be virtually indistinguishable from a "point", and consequently, we measure the "age" of the Universe to be approximately 13.8 billion years relative to a perceived "zero point".
However, because this point is not actually a point, but rather a gravitational wave with no upwards limit to its frequency, we can conclude that the Universe originates and expands from an infinite progression in spacetime. There is no "beginning of time", there only appears to be because observation is limited relative to the totality of the Universe, which is infinite by nature.

Isn't this just a basic logical consequence of time dilation? Furthermore, does this not explain the accelerating expansion of the Universe?
That's what I don't get. So-called "Dark Energy" is obviously just a logical consequence of a shared origin that appears to emerge from (or converge on, depending on how you look at it) a "point". That should never have been difficult for anyone who understands Relativity to wrap their brain around, and yet for some reason it is.

Look to "Does Time Exist...." in Cosmology, for my response regarding an identical 'Guardian' article on the same subject.
