Perhaps most surprising of these is that the spacetime transformation model says that the
coordinate energy density of the universe has remained constant since the beginning of the
universe sincetheBigBang .Thecoordinateenergydensityutilizescoordinatelength and

This answer, obtained from the spacetime transformation model agrees with the answer
obtainedfromtheBigBangmodelthatassumescosmicexpansionoftheuniverse.
Redshift – Frequency Analysis:Therefore,ithasbeenshownthatlookingjustatwavelength
there is the correct redshift when we presume that the redshift is caused by a change in the
backgroundГuratherthananexpansionoftheuniverse.Itispossibletoworkthissameproblem

unanswered.Iftherateoftimewasfasterinthepastthanitistoday,whydon’tweobservea
blue shift on light from distant galaxies? The answer to this question is not obvious in the
previous analysis because that analysis used the “hybrid speed of light C d /dτu. This
definitionincorporatestheproperrateoftimeintheuniverse dτu whichhidesthequestion
about the blue shift. This question can only be answered if we compare proper values to

Thereforewe are using a continuouslyslowing clock totime the frequency of a continuously
slowing rotar such as an electron. This is a moving standard, but each secondan electron is

Therefore,onanabsolutetimescale,whydoesaphoton’sfrequencydecreaseproportionalto

anabsolutescale.Therefore,therotar’sComptonfrequencyappearstobeconstantwhilethe
frequency of a photon decreases when measured using proper rate of time. The standard
explanationofthecosmicredshiftbasedonexpansionoftheuniverseisproposedtobewrong.
Wavelengths are not being stretched. There are no point particles. Particles with finite
dimensions are also affected by the transformation of spacetime. However the effects on
particles are not noticeable because there are offsetting effects on the rate of time, on the
standardofenergyandonotherunitsofphysics.
Maintaining the Vacuum Energy Density:Throughoutthisbooktherehavebeennumerous
referencestotheenergydensityofthespacetimefieldbeingontheorderof10113J/m3 timesan
unknown numerical constant near 1 . The problem is that throughout the history of the
expandinguniverse,theproperenergydensityofvacuumenergywouldhavetoremainconstant.
Theexpandingvolumewouldappeartorequireamechanismtocontinuouslyaddatremendous
amount of new energy to the expanding universe. For example, the Hubble parameter of
2.3 10‐18 m/s/m indicates that each cubic meter in the universe is expanding and
increasing its volume by ~ 10‐53 m3/s. If the vacuum energy density required to fill this
additional volume is Uvac 10112 J/m3, then the additional volume generated by EACH cubic
meter in the universe requires additional 1059 Joules/second. To put this in perspective, the
E mc2totalobservableenergyoftheMilkyWaygalaxyisalsoabout1059Joules.Thereforeit
wouldappearthateachcubicmeterofvolumeintheuniversemustbesuppliedwithabout1059
Joulesofenergyeachsecond.
Therefore, the problem of supplying the universe with dark energy each second is trivial
comparedtotheproblemofsupplyingtheuniversewithnewvacuumenergyeachsecond.This
allseemstobeimpossible,somostphysicistspresumethattheremustbesomemechanismthat
cancels out almost all the implied vacuum energy density in the universe. However, this
hypothetical cancelation mechanism has several problems. 1 Zero point energy, vacuum

NewTransformationsofUnits:Recallthatinchapter3wemadeatableoftransformationsof
theunitsofphysicsshowingthedifferencebetweena“zerogravity”locationandalocationwith
gravity. In chapter 3 we designated the “zero gravity” location as having Г 1. Now it is
necessarytorealizethatthisdesignationincorporatedasimplification.Wewereignoringany
changeinthebackgroundgravitationalgammaoftheuniverseΓu.Anotherwayofsayingthisis
thatwedefineda“zerogravitylocation”ashavingΓ 1.Nowthatwearetalkingaboutthe
evolution of the universe it is necessary to be more precise. The length transformation was
previouslyexpressedas:Lo Lg.However,toputthisinthebiggerperspectivethatincorporates
Γuand ,wecannowsay:
Lo Lg /Γu
Thisequationsaysthatwhatwewerepreviouslycalling Loand Lgwerebothchangingrelative
to our absolute lengthstandard that waspresentat thestart oftheuniverse when Γu 1.
When we are dealing with the universe and time scales where the effects of a changing
background Гu are significant, then it is no longer possible to adopt proper length as the
coordinate unit of length. A different coordinate length transformation is required to

joules in our current universe. Therefore, even though both electrons have the same energy
measured locally, different standards of energy are being used. When we correct for this

because the 1.8 1094 difference in the electron’s energy is offset by the factor of 1.8 1094

This illustrates how the proper energy density of the universe (including vacuum energy)
remains constant even when the universe experiences a vast increase in Гu.
This is a fantastic result because it is a key component in solving the mystery of the 10122
differencebetweenvacuumenergydensityandcurrentlyobservedenergydensity.Whenthe
universe was Planck spacetime, it had energy density of 5.53 10112 J/m3. The spacetime
transformation model of the universe views the current universe as the same size and same
energydensityasPlanckspacetime.Therefore,thetransformationU1 Uusaysthattheproper
energy density of the universe equals the tremendously large energy density of the universe
obtainedwhentheenergydensityisexpressedincoordinateunits.Itisnotnecessarytoadd

also to explain that the energy density of the universe has fallen below the “critical density”.
Baryonic matter, dark matter and radiation only achieve about 28% of the energy density

accuracyofthemodeloftheuniversebeingused.Theconceptof“criticaldensity”oftheuniverse
assumesthattheuniversepossessesagravitationalgradient.Thisdoesnotexistinthecondition

immaturegravityoccursinthelowgravitationalГofthedustcloudthoughtexperimentorthe

Dark Energy Not Needed:Whatisbeingproposedisthatthespacetimetransformationmodel

not need any mysterious force with anti‐gravity properties that is causing the apparent

Are All Frames of Reference Really Equivalent?Abasicassumptionofrelativityisthatall
frames of reference are equivalent. The CMB rest frame is clearly the preferred frame for
cosmologicalpurposes,butthelawsofphysicsarepresumedtoworkequallywellinallframes
of reference. Experimental observations have not detected any preference for frames of
reference,butdoesthismeanthatultra‐relativisticframesrelativetotheCMBrestframeare
equivalent?Recallthatinchapters4and11thesubjectofthespectralenergydensityofzero
pointenergy quantizedharmonicoscillators wasdiscussed.Itwasstated:
“Thisspectrumwithitsω3dependenceofspectralenergydensityisuniqueinas

String theory is based on three starting assumptions which are expressed as mathematical
equations.Theseare1 Lorentzinvariance, thelawsofphysicsarethesameinalluniformly
moving frames of reference 2 analyticity a smoothness criteria for the scattering of high
energyparticlesafteracollision and3 unitarity allprobabilitiesalwaysadduptoone .The
speedoflightisthesameinalluniformlymovingframesofreference,butthelawsofphysicsare
not. Therefore the contention is that Lorentz invariance is not a valid assumption for all
uniformly moving frames of reference. String theory incorporates this erroneous assumption
andalltheconclusionsbasedonthisassumptionarequestionable.
Lorentz Was Correct:EventhoughtodayweoftenassumethatEinsteindidnotbelieveinthe
aether,heactuallycontinuedtorefertotheaetheror“physicalspace”untilhisdeath2.Hemerely
declaredthattheaethermusthaverelativisticpropertieswithnopreferredframeofreference.
Lorentzalsobelievedintheaether,buthiscalculations Lorentztransformations assumedthat
the aether had a preferred frame of reference. Lorentz transformations did not confer and
detectable special properties to this preferred frame of reference since the transformations
madethelawsofphysicsthesamein“all”framesofreference.However,EinsteinandLorentz
disagreed about whether the aether had some special reference frame which served as the
standardforallotherreferenceframes.

The Fate of the Universe:Thecurrentlyacceptedmodeloftheuniversehasmysteriousdark

occurs when the expansion becomes so extreme that gravitationally bound objects such as

Themodelproposedherehasnotbeendevelopedsufficientlytohaveaclearpredictionabout

particular distant galaxy will decrease. This counter intuitive prediction is actually a

possibility. The total energy density of the universe observable energy vacuum energy remainsthesameoverthelifetimeoftheuniverse.Presentlyobservableenergy includingdark
