The concept of virtual particles arises in perturbation theory of quantum field theory where interactions between ordinary particles are described in terms of exchanges of virtual particles. Any process involving virtual particles admits a schematic representation known as a Feynman diagram, in which virtual particles are represented by internal lines. 
In physics, a virtual particle is a transient fluctuation that exhibits many of the characteristics of an ordinary particle, but that exists for a limited time
Are virtual particles really constantly popping in and out of existence? Or are they merely a mathematical bookkeeping device for quantum mechanics?

Nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's quark-gluon sea contribute to a proton's properties. The result comes from work performed by the G-Zero collaboration, an international group of 108 physicists from 19 institutions, and was presented at a Jefferson Lab physics seminar on June 17.

This simple picture depicts pairs of strange quarks as they pop into and out of existence alongside the permanent quark residents of the proton. Nuclear physicists have found that strange quarks, though present for just tiny fractions of a second at a time, also contribute to the proton's properties.
After reading the article on Strange Quarks, it became very apparent that the Strange Quarks create the dynamic equilibrium within a proton. Dynamic is the key word here because without the Strange Quarks, the internal force of the proton would decay through the flow of time. The Strange Quarks contribute a disequilibrium, a counterequilibrium and then back into balanced equilibrium and so on, within the nucleus to maintain the strong force throughout the flow of time. All of this is infinitesimal but it represents a proton's inner functioning as a non-temporal identity - relatively speaking. Of course, consciousness plays the most vital role in all of this - and unfortunately, modern science seems very reluctant to allow such an understanding of reality to seep into the bedrock of its mechanistic paradigm...
Where are you getting this 1% related to strange quarks from? If it's in your source I missed it.

An issue would be that virtual particles when the pop out of the Universe as we understand it end up at some other level. At issue would the Strange Quark and its function to the structure of the Proton.
Which in scientific evaluation is at least 1%.
1% of the mass of the proton is made up of 2 up quarks and 1 down quark, so that 1% is significant, and it can and does have other quarks pop in and out of existence. The source you cited doesn't even mention strange quarks though so I'm not sure where you're getting this 1% whatever related to strange quarks. It would be nice if you would cite a source that had some relation to what you're talking about.

To be honest anyone who would consider that 1% as irrelevant to the structure of a proton is pretty much out of touch with reality, far as I know.
Without the process of the Strange Quark, Protons in would collapse.
Dark energy has topped cosmologists’ “most wanted” list since 1998, when astronomers noticed that the expansion of the universe is speeding up rather than slowing down. The entity responsible—whatever it is—must be incredibly powerful, constituting nearly 70 percent of the universe. Figuring out the identity of this dark energy is “arguably the most important problem in physics,” said Clare Burrage of the University of Nottingham in the United Kingdom.
Now a team of physicists has directly tested one option for dark energy using not powerful telescopes or satellites, but a vacuum chamber fashioned on a tabletop.
The most straightforward explanation for dark energy is that it is the energy inherent in the vacuum of space itself. In this model, every teaspoonful of space brims with the same amount of dark energy, a value known as the cosmological constant. But there’s a major flaw in this simple solution. Physicists’ best calculation of this energy, which is thought to be due to the constant appearance and disappearance of “virtual” quantum particles, overshoots the actual observed value by a factor of 10 to the power of 120..
Introduction to eigenstates
Because of the uncertainty principle, statements about both the position and momentum of particles can only assign a probability that the position or momentum will have some numerical value. The uncertainty principle also says that eliminating uncertainty about position maximises uncertainty about momentum, and eliminating uncertainty about momentum maximizes uncertainty about position. A probability distribution assigns probabilities to all possible values of position and momentum. Schrödinger's wave equation gives wave function solutions, the squares of which are probabilities of where the electron might be, just as Heisenberg's probability distribution does.
So although the researchers did measure the virtual strange quarks in the proton, it appears that these quarks either don't dally long enough inside the proton to have a significant effect on its properties before melting back into strong force energy or don't get far enough away from each other to be seen (i.e. they could have an effect separately, but as a close pair, any effect they would have cancels out).

The title relates to the enigmatic nature of strange quarks like the born pregnant tribbles in the star trek series.
To elaborate strange quarks are simply not their and then there inside the proton of an Atom. This activity keeps everything running but as to what exactly happens to it when it is not there is a mystery and despite that the atoms would collapse without this activity.
Otherwise virtual particles are theorized in relation to Dark Energy.
