Empty space is a vacuum.
The speed of light in any material medium is less than it is in empty space.
The space in between gas molecules is not "just empty space." It is filled with constantly moving and colliding molecules. Gas molecules are in constant motion, so even though there may be more space between them compared to liquids or solids, the space is not truly empty.
Space is not completely empty; it contains matter in the form of gas, dust, and other particles. However, space is mostly a vacuum, meaning it has very low density compared to Earth's atmosphere.
dense
The mass and volumes of electrons are not significant compared to the volume of an atom.
Im looking for this too, it appears to not exist.
Yes, molecules are mostly empty space because they consist of atoms that have a nucleus surrounded by electrons, which are very tiny compared to the size of the nucleus. So, the majority of a molecule's volume is made up of this empty space.
dense
The speed of light and all other electromagnetic wavelengths in vacuum (empty space) is higher than in any other medium.
Everything is mostly space. The diameter of the sun is 865 thousand miles, which is a bit under a million. The radius of the earth's orbit is 93 million miles, almost 100 million. Sedna, which isn't even outside the solar system, orbits 900 times as far (currently).
Empty Spaces was created in 1979.
