Answers
Answer:
you can't imagine what is outside the universe. universe is very vast every thing which can be sensed falls under the universe
Explanation:
see the definition of universe
- all existing matter and space considered as a whole; the cosmos. The universe is believed to be at least 10 billion light years in diameter and contains a vast number of galaxies; it has been expanding since its creation in the Big Bang about 13 billion years ago.
- so universe is sooo big and keeps on expanding .

Answer:
Thanks for asking a interesting question!
Yes, Our Earth is too far away form our moon but still it's looks like the Moon is closer to our Earth, It's because the appearance of the Moon is brighter in the night sky. At night even if the moon doesn't emit it's own light, The moon looks like it produces it's light by its own but actually its reflects the light to us at night and make a bright light throughout the night. The sun emits the light and this light is reflected to the Moon and this makes the night bright in our Earth.
We know that our Moon is our natural satellite also the Moon is 81 times larger than our Earth, Its appearance is like a huge ball in the night sky, In moon there's a huge hole in the size of our Earth that's a astroid have crashed into the moons surface. If the orbital period of our Earth is 365 days, the orbital period for moon is just 27 days. Moons surface is about 3.793 × 10^7 square kilometer. Moon is also known as Luna and with many more words.
You may have got doubt when you were small like, how do we float in moon and space but why not in our Earth: The reason in because of gravitation. The gravity on our Earth is 9.807 m/s² but on Moon the gravity is about 1.62 m/s². The distance from our Earth to moon is about (4.063 × 10^-8 - Light years) that's (384,400 kms). To be noted:- The distance measured in space form one celestial body to other is in the unit of Light years.
We couldn't even think how big is our universe, because it's that big and to say in one it's endless. No one had even said how big is our universe and also not even the great space scientists. According to me it's just Endless, because...There are so many planet's in our Galaxy and they are lakhs of galaxies in our Universe and also there are millions of Universes inside a Multiverse.
This is really a wonderful theory, according we know Big Bang theory and also the difference concept based on Multiverse, There are millions of planets which many unknown mysterious creatures and plant's are exist. We couldn't even predict how big is this Universe and we can't say that it's just a blank space because they are many stars, planets, coments, astroids, and other celestial bodies exist.
Scientists all over the world have been researching about new plants and celestial bodies each and ever day and it's really great and awesome to know about the life evolution and Multiverse, Formation of universe and more. There are many interesting things in space to known such as wormholes, black hole, white hole, etc. There are several things to learn about time travel which is not possible and we don't know about it.
We know that there are several space research organization such as NASA, ISRO, etc have been doing several researches each and every day, Before few years the NASA has sent a space telescope into the space for several light years and also that space telescope has captured the images and information's about a similar plant like earth. So this proves that talking about space is Endless and also taking about parallel universe which connect the life our organisms and planets to one universe to another universe.
.. Parallel universe is a Parallel dimension universe, Parallel universes are twin universe which has the life evolution connection form one universe to another. Several types we get dreams like being in different place and talking with anonymous people but these are a part of parallel universe dimension which connects the life of the organisms form one universe to another.
In parallel universe, both dimensional universe have the same planets and same life system with different minds there is a lots of connection to Parallel universe with the Simulation theory. Such as many parts of our brain still doesn't recognised by the doctors or scientists, because our Brain is our simulator, Doctors still doesn't know how to treat a coma patients with the proper treatments.
Lucid dreams, this topics undergoes into the topic of Parallel universe, We dream about the people and organisms in the second dimensional of our universe. There's a most famous story named "A man form Tornado" read it and known more about parallel universe and lucid dreams.
