In part, this comic is an homage to the referenced podcast, ''{{w|My Brother, My Brother, and Me}}'', which often features rapid garden-path conversations and puns and double entendres that are at once groan-worthy and delightfully witty. "MBMBAM" is an acryonym of "'''M'''y '''B'''rother, '''M'''y '''B'''rother, '''A'''nd '''M'''e". | In part, this comic is an homage to the referenced podcast, ''{{w|My Brother, My Brother, and Me}}'', which often features rapid garden-path conversations and puns and double entendres that are at once groan-worthy and delightfully witty.

| − | The millibar is a metric unit of pressure (force per unit area), equal to a thousandth of a {{w|Bar (unit)|bar}}, or 100 {{w|Pascal_(unit)|Pa}}.

Both units would theoretically have the symbol '''mb'''. Hence '''mbmb''' (the pressure unit multiplied by the area unit) would be a unit of force. This can be seen by applying dimensional analysis; pressure x area = (force/area) x area = force. Nobody in the comic strip discusses the magnitude of this force, but it would be 100 Pa x 10^-31 m^2 = 10^-29 newtons, or about the weight of an electron under Earth's gravity. |
| − | '''am''' would be the symbol of an {{w|Atto-|atto}}meter, or 10^-18 meters. Multiply that to create the unit '''mbmbam''', which would be a unit of energy. Specifically, it would be a unit of work: the energy expended to move an object. More dimensional analysis: force x distance = (work/distance) x distance = work. The actual value of 1 mbmbam is correctly calculated in the comic: 100 Pa x 10^-31 m^2 x 10^-18 m = 10^-47 joules | + | '''am''' would be the symbol of an {{w|Atto-|atto}}meter, or 10^-18 meters.

The final panel is an extended series of puns: 'rise' referring to physically moving upward as well as biologically growing (expanding and becoming lighter and softer) as yeasts do; 'foam' referring to both {{w|quantum foam}} (the fluctuation of spacetime on very small scales due to quantum mechanics) as well as the foam generated by yeast fermenting; 'unleavened dimensions' punning on the eleven dimensions of spacetime in {{w|string theory}} (actually, ten—{{w|M theory}} says eleven), while continuing to play on the theme of yeast--in this case, the universe is presumably flat because some of its dimensions lack the Planck yeast that would make them rise. White Hat appears to have managed to have caught onto these puns, much to his (extreme) dissatisfaction. | The final panel is an extended series of puns: 'rise' referring to physically moving upward as well as biologically growing (expanding and becoming lighter and softer) as yeasts do; 'foam' referring to both {{w|quantum foam}} (the fluctuation of spacetime on very small scales due to quantum mechanics) as well as the foam generated by yeast fermenting; 'unleavened dimensions' punning on the eleven dimensions of spacetime in {{w|string theory}} (actually, ten—{{w|M theory}} says eleven), while continuing to play on the theme of yeast--in this case, the universe is presumably flat because some of its dimensions lack the Planck yeast that would make them rise.

(The {{w|Planck length}}, approximately 1.6×10^−35 m, is how far light travels in one unit of {{w|Planck time}}.) Another interpretation of 1 mbmbam would be the work necessary to pull two socially distancing (6 ft) SARS-CoV-2 {{w|Virus|virions}} apart by the thickness of a single strand of hair against the gravity they exert on each other. |
The Planck Era (or {{w|Planck_units#Cosmology|Planck Epoch}}) referenced in the title text is the near infinitesimally short period covering the first 10^-43 s after the Big Bang, when energies were so high that the four fundamental forces were combined into one and ordinary subatomic particles didn't yet exist. It is unlikely there were advice shows during this era{{Citation needed}}, so this would likely be a modern nostalgia show for physicists. The title text is also a play on My Brother, My Brother and Me's tagline: ''An advice show for the modren [sic] era.'' | The Planck Era (or {{w|Planck_units#Cosmology|Planck Epoch}}) referenced in the title text is the near infinitesimally short period covering the first 10^-43 s after the Big Bang, when energies were so high that the four fundamental forces were combined into one and ordinary subatomic particles didn't yet exist.
