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.
Not only is the universe expanding, but this expansion is also accelerating so the unknown 'anti-gravity' force at work is termed 'dark energy'. Some researchers are searching for an explanation that encompasses both dark matter and dark energy. One example of such a theory uses a form of energy called a scalar field (it is a field because it has magnitude, energy and pressure, but it is scalar so it has no direction). Things would certainly be easier if we didn't need to have separate theories to explain dark matter and dark energy.
