There are speculations about other universes, but for now, there is no way to prove that they exist. Or to disprove them, for that matter.It isn't clear what you mean by "negative universe" - what exactly would be "negative"?
Universe
Astrobiology deals with the origin of the universe, the universe's composition, future of life in the universe, distribution of the universe, etc.
The universe IS space, plus everything that's in it.
Universal (pervading the universe) or cosmic(relating to the universe).

Positive and negative
Because of the miscellaneous-nees of the universe, it is a very hard miscellaneous task to study the universe. You have to see the positives in it, you cant be negative about it or the universe will get mad.
This is a theoretical model of the universe. A Friedman Universe can have positive, zero or negative curvature. If the curvature is positive then the universe is closed and curved. A light ray going in any direction would make a complete circuit if the universe and return to the starting point. If the universe has zero or negative curvature it is open and unbounded and said to be flat. A light ray would travel in a 'straight' line and not return to its point of origin.
42... The answer to life, the universe and everything
It can be both positive or negative, all depending on your mind set. The universe will not tell the difference between a positive or negative thought. Only what your mind is focused on. What ever you focus your energy of thought on, the universe will help conspire to make it so. focus on positive ideas and they will become reality, but focus on negative ideas and they too will become reality.
Yes, as long as the entropy of the universe increases.
A "no boundary" universe is a universe where the change in energy is positive or negative everywhere in the universe. Such a universe theory calls for everywhere expansion or everywhere contraction. The current central dogma in Astronomy is for such an expanding universe. The corrected Law of Gravity indicates that the universe is bounded and not expanding.
Actually interesting enough it may be as simple as just ZERO. Because by you asking the amount of energy in the Universe, you are forgetting about the negative amount of energy that is also made up in our universe. For every positive energy there should be a negative, with simple math skills this basically adds up to zero.
Positive: Find out more about the universe Negative: Waste money that could be used on Earth Not many discoveries concern Earth There is a small possibility we are announcing our existence to intelligent beings in the universe who could harm us if given a chance
Assuming you mean can entropy be reduced; the answer is yes. Only in an open system such as our planet. The universe is a closed systems. The entropy of the universe cannot be reduced. Chemical changes can reduced entropy in an open system. When gas turns into a liquid or when a liquid turns into a solid; entropy is reduced.
Because that is how the universe was made. The law of charges states that opposite charges attract.
