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.
Dark matter may be made of baryonic or non-baryonic matter. To hold the elements of the universe together, dark matter must make up approximately 80 percent of its matter. [Image Gallery: Dark Matter Across the Universe ]. The missing matter could simply be more challenging to detect, made up of regular, baryonic matter.
