  • Inflation


The matter components of the universe
The matter components of the Universe

  • Concordance!!.

  • M ~ 0.27  0.1,

  •  ~ 0.73  0.1

  • 0 ~ 1.

  • The matter component

  • M = b +  +  ~

  • 0.04 + DM,

  • where DM ~ 0.23.

  • but

  • DM ni  ??.

    DM + ~ 0.96

  • p= r

  • =A0+A1a=0+a z/(1+z)

  • Constante Cosmológica: 0 = -1, 1 = 0

  • Quintessence: f

  • Phantom: K=-,,

  • Quintom: f1 + f2

Across the Universe

Las palabras surgen a raudales como una lluvia infinita en un vaso de papel Se deslizan al pasar Desaparecen a través del universo Charcos de tristeza, olas de alegría flotan en mi mente abierta Poseyéndome y acariciándome Jai Guru De Va Om Nada cambiará mi mundo Nada cambiará mi mundo Imágenes de luz que bailan ante mí como un millón de ojos Que me llaman y me llaman a través del universo Pensamientos serpenteando como un viento inquieto en un buzón Tambaleándose ciegamente mientras hacen su camino a través del universo Jai Guru De Va Om Nada cambiará mi mundo Nada cambiará mi mundo Sonidos de risas y sombras de tierra suenan a través de mi vista abierta Incitándome e invitándome Un amor eterno y sin límites brilla a mí alrededor como un millón de soles Llamándome y llamándome a través del universo Jai Guru De Va Om Nada cambiará mi mundo Nada cambiará mi mundo
