Vaccines are a boon in eradicating various lethal diseases and increase the immunity of the people. The development of vaccines started with the understanding the cell itself, various pathways that regulate its fate. The immunology, a branch of biological science, gave the idea of the working of the defense or the immune system of the body, and of the various specia cells that function for it. This led us to the discovery of antibodies and antigens. Vaciines are artificial means of injecting antigens into the body to generate antibodies beforehand, so that the immune system remembers producing it at the time disease causing agent strikes us.
Thus, we can summarise that STEM research or core science research has led to innovations that have shaped our lives and lifestyle to contribute to an overall good social health.
Astronomers use light years to measure distances in space because space is so massive and distances so far that conventional numbering is inadequate and unmanageable. One light year is a distance measurement equivalent to six trillion miles.

Sound would travel faster in a thick piece of metal since the molecules are closer together. However, since there are more molecules, it would be quieter on the other side than the hollow metal.
Explanation:
If water did not expand when freezing, then it would be denser than liquid water when it froze; therefore it would sink and fill lakes or the ocean from bottom to top. Once the oceans filled with ice, life there would not be possible.
