Microplastics are small plastic particles in the environment that are generally smaller than 1 mm (0.039 in) down to the micrometer range. They can come from a variety of sources, including cosmetics, clothing, and industrial processes.
Two classifications of microplastics currently exist: primary microplastics are manufactured and are a direct result of human material and product use, and secondary microplastics are microscopic plastic fragments derived from the breakdown of larger plastic debris like the macroscopic parts that make up the bulk of the Great Pacific Garbage Patch. Both types are recognized to persist in the environment at high levels, particularly in aquatic and marine ecosystems.
Because plastics do not break down for many years, they can be ingested and incorporated into and accumulated in the bodies and tissues of many organisms. The entire cycle and movement of microplastics in the environment is not yet known, but research is currently underway to investigate this issue.

I was reading that gravitational waves have now been detected further proving Einstein's General Theory of Relativity (GR). If apparently confirms that both space and time are related and can be deformed and bent. It also means that "time" did not exist before the "big-bang" and creation of the universe.
First I'm not getting near any singularity! Second its a good thing the Nazi Party didn't pursue Einstein's physics with the same intensity as that carried out in the "Manhattan Project". Guess why.

Probably it has some "relative" benefit but difficult to measure.
Speaking of science why does government spend so much money on it. If government has so many experts why don't they invent the next new i-phone? Or is the cliche' true; those that can, do. Those that can't give grant money away.
President Eisenhower may have had it right when he remarked; when government invests in science it becomes less science and more politics. Amen to that.
