We live on Earth. A small red dot. On this image we are covered by the white cloud somewhere near the top right centre. So we live in Singapore, which is on Earth. Where is Earth?
The Earth is in our Solar System. Count the rings, we're the little blue ball sitting on the 3rd ring (orbit) from our Sun. So the Earth is in the Solar System. Where is our Solar System?
Our Solar System is in the Milky Way (Below). Can you even see Earth? or our largest planet - Jupiter? Or our humongous Sun? So our Sun and our solar system lives in the Milky Way. Where is the Milky Way?
Our Milky Way is in the Local Group. Our Milky Way Galaxy shares this Local Group area with several other Galaxies. I've provided 2 images of our Local Group below. So our Milky Way Galaxy is in the Local Group. but where is the local group?
Our Local Group is part of the Virgo(Local) Supercluster. See that small point near the centre of the image? That's where our Local Group is. If you could use a microscope on this image, Earth would probably be smaller than what bacteria would look like in a lab under the microscope. Now, again, where is this Virgo Supercluster in space?
We don't know. Because beyond the Virgo Supercluster is merely The observable universe (the universe as we can see). We can't see very much further. and beyond that is simply just called "universe". Where does it end? We don't know.
Can you imagine?
[Note: some parts were skipped to keep this post short]
In summary,
YOU are at home (or whereever), your home is in Singapore. Singapore is a little red dot in Asia. Asia is a small less than 15% part of the planet Earth. Earth is a small little tiny ball orbiting the Sun in our Solar System. Our Solar System is within a Local Interstellar Cloud which is within a Local Bubble which is in turn part of the Orion Arm which is in one mini corner of the Milky Way which is a small area in our Local Group which is in turn a tiny point within the Virgo Supercluster which is just a small speck of "dust" in... the Universe.
Now.. how big are we? -
