Invisible Universe Int. Conf - 29 June – 3 July 2009 — Paris, France Background Dark Energy is usually invoked to explain the expansion of the Universe But is the Universe expanding? If not, there is no need for dark energy. 2

Invisible Universe Int. Conf - 29 June – 3 July 2009 — Paris, France Universe Expansion : Evidence In 1929, Hubble discovered the light from distant quasars was redshift Based on the Doppler effect, the Hubble redshift was interpreted as the expansion of the universe. 3

Invisible Universe Int. Conf - 29 June – 3 July 2009 — Paris, France Purpose Show Hubble redshift is produced in cosmic dust by QED induced EM radiation QED = Quantum Electro Dynamics EM = Electromagnetic 4

Invisible Universe Int. Conf - 29 June – 3 July 2009 — Paris, France Hubble Redshift By Doppler’s effect, the velocity V of the Supernova relative to Earth, Z = Redshift o = Redshift wavelength = Supernova line c = Speed of light 8

Invisible Universe Int. Conf - 29 June – 3 July 2009 — Paris, France QED Induced Redshift Quantum Mechanics requires the heat capacity and specific heat of submicron DPs to vanish. Absorption of Supernova photon cannot be conserved by an increase in DP temperature. QED induces the Supernova photon to increase its wavelength to the EM wavelength of the DP The EM confinement of the DP leaks the QED induced photon as redshift EM emission. 9

Invisible Universe Int. Conf - 29 June – 3 July 2009 — Paris, France Heat Transfer in DPs Classically, EM energy absorbed by a body is conserved by an increase in temperature Astronomers have assumed DPs to have specific heat to conserve the absorption of starlight photons in a DPs by an increase in temperature But QM requires the specific heat of submicron DPs to vanish at temperatures of 2.7 K 10

Invisible Universe Int. Conf - 29 June – 3 July 2009 — Paris, France Reddening and Redshift Reddening occurs by scattering, but also occurs by QED induced redshift Consider a D = 280 nm amorphous silicate DP absorbing Supernova photons having wavelengths shorter than the EM confinement at o = 810 nm. All Supernova photons are redshift by QED to produce one or more red 810 nm photons indistinguishable from those produced by scattering Treating the red photon at 810 nm as redshift of the Ly  line at nm, the QED induced redshift Z = 5.7 The Hubble Law gives the Universe expanding at velocity = c with the Supernova at 4096 Mpc from the earth But the Universe is not expanding !!! 16

Invisible Universe Int. Conf - 29 June – 3 July 2009 — Paris, France Infrared Spectra Astronomers treat the observed IR spectra as thermal emission from the absorption of a single UV photon by a DP. For IR from 2 to 25 µm, temperatures < 1000 K !!! A single 0.25 µm UV photon absorbed in a 8.62 µm amorphous silicate DP is QED redshift to o = 25 µm with the temperature remaining at 2.7 K The IR spectra is produced in DPs upon absorbing galactic light For IR from 2 to 25 µm, the QED induced redshift 7 < Z < 99 But the Universe is not expanding !!! 17
