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.
Whatâs the Difference Between Dark Matter and Dark Energy? Dark matter and dark energy are the yin and yang of the cosmos. Dark matter produces an attractive force (gravity), while dark energy produces a repulsive force (antigravity). Together, they make up 96 percent of the universeâand we canât see either. Astronomers know dark matter exists because visible matter doesnât have enough gravitational muster to hold galaxies together.
