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.
By Andrew Zimmerman Jones. Definition: Dark energy is a hypothetical form of energy that permeates space and exerts a negative pressure, which would have gravitational effects to account for the differences between the theoretical and observational results of gravitational effects on visible matter.nstead of a steady expansion, or a slowing expansion, the expansion rate is getting faster, which means that Einstein's original cosmological constant prediction manifests in today's theories in the form of dark energy. The latest findings indicate that over 70% of the universe is composed of dark energy.
