No.
Sentience is not one dimensional but five: cognitive, recognitive, sensory, inherent, and logical. Each of these has a range value therefore the measure of sentience is n5 variable value.
Yes. It might be possible that there are countless sentient species in the universe, but we do not know for now.
Despite much debate among people and scientist, there is no official proof that there are countless semi-sentient species in the universe.
In my opinion, yes. There are at least 10,000 trillion sentient species (100,000 per galaxy) in the observable universe.
Though some scientist say there is a possibility that there are countless non-sentient species in the universe, there is no concrete proof right now to be sure.
There are 10 million trillion Earth-like planets with sentient life (100 million per galaxy) in a fictionalized version of our universe.
Currently it is not known. Earth is the only known planet to hold life so far. It also depends at what point you consider a living thing to be sentient.
Because those who pray, they do so on behalf of all the sentient beings of this universe.
Yes! A Universling is a bit of sentient cosmos that knows that it is a bit of sentient cosmos. Confusianism is essentially exactly that. The biggest difference between them and Universlings of our time is that now we understand the universe far better than we ever did. - I am a bit of universe bewildered by the fact that a bit of universe has the capacity to feel bewilderment at all.
It isn't currently known whether there is even a single species outside Earth - sentient or otherwise. The number you mention has been made up by somebody.
If you mean the video game, then it was an ancient weapons system that could wipe out all sentient life in the universe
To make 100 billion separate books of all of the information of 10,000 trillion sentient species (100,000 per galaxy) in our universe, you would need to begin by researching each species. Then combine the information using a computer.
Matter is the structural component of the universe that possesses inertia and volume under the influence of gravitation, that is perceptible to sentient beings, and that is convertible to energy.
