Sound cannot travel through a vacuum, scientific or any other kind
it travels at c (speed of light in a vacuum)
When light travels through anything that is not a vacuum, it will usually slow down.
In a vacuum, light always travels at the same speed, about 300 000 kilometers per second.
Energy from the sun travels through the vacuum of space by radiation.
yes
Nothing. It continues to propagate at the speed of light, and is not diffracted or distorted except by negligible gravitational effects.
yes as radiation travels from the sun through a vacuum to earth
Light travels fastest through vacuum.
light travels from sun to earth through vaccum, so its easily understood
As the medium through which light propagates in space is closes to a vacuum, light propagates very well in space. However, it travels at the same speed as it would on earth, as light travels at 299,792,458m/s in a vacuum, regardless of where that vacuum is located. the light travels in same speed whether it travels in space or earth.
You create a vacuum in a lab, and then shine a light through it, and there is experimental proof that light travels through a vacuum. Alternatively, take the fact that light travels through space - if light could not travel through a vacuum, no light from the stars, the moon or the sun would ever reach our planet.
Heat travels through vacuum as electromagnetic radiation, exactly the same way that light and radio do.
