You’ve probably seen the photos of the
Great Pacific Garbage Patch—the enormous, swirling dump that (unfortunately) we’ve created in the middle of the ocean. It is filled with bottles, old plastic bags, bits of houses…and pretty much everything else that humanity has flung away (or just failed to properly clean up). Reports assert that, each year, for every foot of coastline, there are a staggering 5 garbage bags full of plastic added to the ocean. But it's not like we can really measure this, so how did we get this estimate?
Similarly, we know that
the Big Bang happened some 14 billion years ago, and that
the oldest stars started forming about 350 million years after the universe came into being. But we obviously weren't there to see it, so how can we know the age of the universe or the various cosmic objects that populate it?
We are collaborating with scientists from the Rochester Institute of Technology (RIT) to bring you a weekly podcast hosted by astrophysicist Brian Koberlein (
One Universe at a Time). In this week's episode, RIT scientists Matthew Hoffman and Brian Koberlein discuss the aforementioned quandaries.
The One Universe at a Time Podcast is produced at the Rochester Institute of Technology with support from the RIT College of Science.
