Inflationary cosmology gives a plausible explanation for many observed features of the universe, including its uniformity, its mass density, and the patterns of the ripples that are observed in the cosmic microwave background. Beyond what we can observe, most versions of inflation imply that our universe is not unique, but is part of a possibly infinite multiverse. The speaker describes the workings of inflation, the evidence for inflation, and why he believes that the possibility of a multiverse should be taken seriously.

Multiverse has been proven both experimentally & theoretically:
(1) experimentally from 10+ billion 1Hz gravity measurements by (Canadian) superconducting gravimeter as Earth’s most accurate instrument (used for studying G):, and (2) mathematically by expressing value of G (and thus g) via c on both quantum and mechanist scales, as hinted by Einstein in 1930s (, and (3) multi-physically (w/o units since no one knows what they would be in another universe i.e. they have no multiversal meaning) as Newton attached units to G only in order to close his own (our universe's) physics: Finally, (4) Paris Bureau of Weights & Measures confirmed Omerbashich (first and only) theoretical value of G: Note (5) tidal influence by another universe was first proposed in

definitely, Scientist and scholar Rabah Al-Shanti of Jordan have proven this through his book published in September 2014 and his latest videos on the you tube that has some English Briefing. He concluded the existence of seven earths like ours in seven solar systems like ours. our earth exists in solar system SS5, he even puts his theory for the end of days and how it actually shall happen .....kindly, check his videos specially those on the below links and try to follow the illustrations he made within the videos

I have checked the two videos of writer rabah shanti, and there is very small commentary below the videos in English, but the videos are made in Urdu or Arabic, but the illustrations within the videos seem very interesting especially they can be understood due to using Latin names.....if this is true, NASA should search for the guy especially that in his FB page, he suggests a theory for travelling in time.
very interesting and hope to read full translation of his book and work.

as a Muslim, I am so proud of the work and research of rabah shanti, as it opens up New horizon for better understanding of quran
