and we don't know what else could be out there.... what do you think??

well I don't know, I mean, the word Universe means EVERYTHING... but yeah, I get your point.. we've just explored almost nothing of our own universe... there could be other places, anything is possible.

Hello Sweet Princess.
The answers to your questions are
No and No.
Your question uses the term "Universe" rather loosely and I suspect that you mean our "Solar System", not our Universe.
The Universe is everything around us out to as far as it goes in all directions.
Our Galaxy is named the Milky Way Galaxy and it is made up of more than 200 Billion Stars just like our Sun. Our Sun has a number of planets (some with moons) orbiting around it in a Solar System. Each of those other 200 Billion Stars (+, or -) could have similar groups of various planets (and their moons) orbiting around them in similar solar systems.
Beyond our Galaxy, there are thousands and thousands of other galaxies, and each one of them might have Billions of Stars with their own solar systems of planets and moons.
The sum of all of that plus millions and millions of things we have not discovered yet is our Universe. And, I am sorry to say that we have not explored a tiny fraction of it yet. What we have done is sent probes (photographic and data collection models) to various parts of our Solar System, a lander and robot explorers to Mars, and actually sent live people to Earth's Moon and back. We actually have at least two probes way out in Deep Space traveling away from Earth at an astonishing rate of speed. But, with all of that said, we have only focused on our Solar System, not the Universe as a whole. The nearest Star (not our Sun) is about 4.5 Light Years away from us, so any probe sent there would take a long, long, long time to get there, and radio signals (traveling at the speed of light) would take around four years to reach us when the possible probe got into that vicinity, and about 4 years for a command instruction to go back the other way.
The "Universe" is so unbelieveably vast, it is just not possible to conceive of their being another Universe. Scientists and Astronomers can "see" out into deep space with their most elaborate optical and radio telescope equipment to a distance of 40 Billion Light Years in all directions from Earth right now. That is not the end of the Universe, that is just the distance at which our observation equipment fails to provide any further useable information.
Regards, Zah

We have only "explored" less than one trillionth of a percent of our universe, not 20%. (unless by "universe" you mean "solar system")
With present technology, it's a bit pointless to speculate about other universes, since the expansion of our universe exceeds light speed (relative to us) at its farthest points, so we will never be able to explore past those points anyway.

Multiple and parallel universes are predicted by higher mathematics in cosmology. We also cannot explain where all the matter that falls into black holes goes to; we believe it goes into another dimension and another universe.

yes, we can't say 20%. it will be too big for us. universe is too vast and our earth is like a dust particle in it. there can be other universe too, but its not nessary that life form will be present there. but there is maximum possibility of other universe.

No I think space just stops!!! Yes I think there is other life also..
