Scientifically marbles do not pop in and out of existence. They SHOULD because quantum physics should apply to large objects as well, but they don't, for some reason.
If you can't repeat an event, then science is useless to examine it.
And even then, science is HOPING that they are recreating an event accurately.
Here is another response to your quote.
Marbles don't pop in or out of existence because the energy (or mass) of the marble is not obtained from the vacuum energy which is the lowest energy level in a field.
The energy-time relationship of the Heisenberg Uncertainty Principle states ΔEΔt ≥ h/4.
Since marbles hang around for a long time Δt is very very big which means ΔE is very very small.
This would mean marbles for all intents and purposes would have to have masses of the same magnitude as particles such as protons and neutrons which of course is nonsense.
Since protons and neutrons have been mentioned a free neutron (n) decays to a proton (p) according to the reaction.
n → p + e⁻ + ῡₑ where e⁻ and ῡₑ are the electron and antineutrino respectively.
This is a straightforward reaction where energy is conserved.
When we look at the reaction at a more fundamental level using a Feynman diagram things look decidedly weird.
In the diagram the W⁻ boson which is the carrier for the weak force pops into and out of existence when a neutron decays into a proton and hangs around with a half life of Δt ≈ 3 x 10⁻²⁵ s.
Since its half life is so short its mass is around 80X greater than the neutron which has been confirmed by experiment.
So where did the mass of the W⁻ boson come from; certainly not from the neutron but from the (Higgs) vacuum energy of the field.
