Are there at least 130 octillion people in the observable universe?

It is impossible to estimate how many people exist in the universe since we have no way of knowing how many worlds have life and how many of those have produced life forms that might be called people.

Are there at least 90 billion trillion planets in the observable universe?
Yes. There are at least 90 billion trillion or more planets in the observable universe.
Are there at least 10000 trillion sentient species in the observable universe?
In my opinion, yes. There are at least 10,000 trillion sentient species (100,000 per galaxy) in the observable universe.
How can astronomers make an atlas of at least 100 billion galaxies in the observable universe?
No. Because it will be impossible for astronomers to make an atlas of at least 100 billion galaxies in the observable universe.
Will the PGC catalog have at least all 100 billion galaxies in the observable universe?
No, because it will be impossible for the PGC catalog to have at least all 100 billion galaxies in the observable universe.
Are there at least 10 billion trillion Earth-like planets in the observable universe?
In my opinion, yes. There are at least 10 billion trillion Earth-like planets in the observable universe.
Are there at least 12.6 million billion or more intelligent alien civilizations in the observable universe?
In my opinion, yes. There are at least 12.6 million billion or more intelligent alien civilizations in the observable universe.
How many galaxies are in the Observable Universe?
at least 100 billion or more.
How can astronomers survey at least 100 billion galaxies to make a 3D map of the observable universe?
No, because it will be impossible for astronomers to survey at least 100 billion galaxies (each with 100 billion stars) to make a 3D map of the observable universe.
Is the universe made up of hundreds of millions of galaxies?
Much more than that, actually. The number of galaxies in the OBSERVABLE Universe is at least 1011.
Are there at least 7 trillion or more dwarf galaxies in the observable universe?
Yes, the current Dwarf galaxies in the visible universe are 7 trillion.
Why is our estimate of the size of the universe smaller than the observable universe?
Among other things, it would be a great coincidence that the Universe ends right where our instruments can no longer observe anything.Moreover, there are reasonings based on cosmic inflation, according to which the Universe must be at least a thousand times larger than the observable Universe. This is related to the isotropy of the Universe in the observable part. Any initial anisotropy must be spread out over a much, much larger region of space.
Are there at least 350 billion or more giant galaxies in the observable universe?
No, while we do not know the actual figure best current estimates are that there are around 200 billion observable galaxies.
