Resin versus acrylic free standing tub. I have found 2 similar tubs 71-72 inches - resin by Signature Hardware (Winifred) or acrylic Hydrosystems (Picasso). They are close to same price but the Signature Hardware brand is made of resin, not acrylic. Does anyone know which material is superior and why?
Hot or Cold Dark Matter and Cosmology. Hot and cold dark matter are the two key elements in modern cosmologyâs quest to understand how our universe formed as we see it today. Much effort is being expended to determine whether 23% of the universe, which is attributed to dark matter, is either hot or cold.
We believe most of the dark matter is composed of new particles smaller than atoms that are different from anything scientists have ever detected and studied. It seems that the very essence of most of the matter in the universe is different from what you and I and rocks and trees and Earth and the Sun are made of. Trying to understand dark matter is one of my favorite topics in science, so I'm glad I had the chance to shed some light on it for you.
