Well, isn't that an interesting question. You see, there are billions and billions of stars in our beautiful, vast universe, each one potentially with its own planets. Scientists estimate that there could be trillions of solar systems out there waiting to be discovered, just like little hidden gems in our cosmic painting. Can you imagine the possibilities?
There are currently no known means to actually separate parts of the universe physically from the rest of the universe.
It is currently unknown how many Earth-like planets exist in the universe. Scientists have discovered thousands of exoplanets, some of which may have conditions favorable for life, but the exact number of Earth-like planets is still uncertain due to the vastness of the universe.
If you believe in heaven then it can be anywhere you want. If you believe in science, then it does not exist. Observations from space have shown no "heaven" or anything like it exist, so it's more than likely that it does not exist apart from in religious books and peoples minds.
This is not currently known. There does exist some asymmetry between matter and antimatter - meaning that they are not exact opposites in all aspects - but this asymmetry is not enough to explain why matter exists.
The region of the universe outside the system being studied is known as the environment. It consists of all factors and entities that can potentially influence the system but are not part of it. Understanding and accounting for the environment is crucial in systems thinking and analysis.
The most massive elementary particle known to exist in the universe is the top quark.
Currently there are 353 known extrasolar planets (that is to say, outside of our solar system), but it is unknown how many planets exist in the universe.
Life is known for certain to exist on Earth. While there are potential signs of past life on Mars and potential for life elsewhere in the universe, Earth is the only confirmed location where life currently exists.
There are about 1011 (a 1, followed by 11 zeroes) galaxies in the known Universe. It is not currently known how much bigger the entire Universe is, compared to the known Universe.
Currently it is not known. With current technology, we are not able to detect the presence of life on other planets even if it does exist. However, we now know that planets are relatively commonplace, which many scientists believe strongly suggests that life must exist elsewhere in the universe.
It is not currently known for sure whether such a thing exists.
Answer:The biggest thing known to man is the Universe (Not observable universe) But if Omniverse exist, that would be the biggest thing known to Man.
That depends on whether the Universe itself is infinite. It is not currently known whether this is the case.
All elements and compounds can exist as a gas if heated sufficiently.
"Objects" generally doesn't refer to living things, but the only life in the universe that is currently known to exist is contained on Earth. (However, certain precursors of cellular life are likely to exist elsewhere, if not full life-forms)
What is known as the Big Bang Theory is the currently recognized model of how the universe began.
Earth is currently the only planet where it is known that beings can exist. However in my opinion the universe is so unthinkably huge that there must be another planet where there are the right conditions for life.
