Answers
1) Yes, radio antennas can emit visible light, but probably not in the way that you're thinking. ... As you may have learned, electromagnetic waves come in many different frequencies, from radio, infrared, visible, and ultraviolet to x-rays and gamma rays.
2) Yes, sound waves can generate heat. In fact, sound waves almost always generate a little bit of heat as they travel and almost always end up as heat when they are absorbed. Sound and heat are both macroscopic descriptions of the movement of atoms and molecules.
3) Yes, the decay half-life of a radioactive material can be changed. Radioactive decay happens when an unstable atomic nucleus spontaneously changes to a lower-energy state and spits out a bit of radiation. This process changes the atom to a different element or a different isotope.
4) The mass of an object therefore does not change when it travels at high speed. This fact is predicted by Einstein's theories and verified by experiment. An object can never be turned into a black hole, or even be made slightly overweight by speeding it up.
5) Supersonic airplanes break the sound barrier by flying faster than the speed of sound. This is possible because sound is just a traveling vibration of air molecules. ... By analogy, if a space ship traveled faster than the speed of light, it would create a shock wave made entirely of light.
6) Yes, you can make a sunset in a cup of milk. ... The physics that makes your cup of milk orange and red is the exact same physics that makes the sky at sunset orange and red. In this sense, you can literally make a sunset in your cup of milk.
