Gravitational Waves

In physics, gravitational waves are ripples in the spacetime curvature which propagate as waves, travelling outward from the source. Predicted in 1916 by Albert Einstein on the basis of his theory of general relativity, gravitational waves transport energy as gravitational radiation.

Watch A Bubble Instantly Freeze

A bubble is formed when a layer of water molecules is trapped between two layers of soap molecules. Each soap molecule is positioned so one side faces the water, while the other faces away.

No matter what shape a bubble creates when its first blown, it eventually forms a sphere to minimise the surface area of the structure. This shape uses the least energy to form.

Boeing created world's Lightest Microlattice Metal

Boeing says it's created the lightest metal ever, a microlattice material which it describes as 99.99% air.
Weight savings are crucially important in aircraft manufacturing, since a lighter aircraft requires less fuel, which is airlines' largest operating expense.

Scientists conduct most precise test to date of light speed finding Speed of Light is indeed Constant

Physicists have reported the most accurate test to date of Lorentz symmetry for photons by looking for variations in the speed of light, but found no violations. The study, by Moritz Nagel at the Humboldt-University of Berlin, Stephen Parker at The University of Western Australia, and their co-authors, is published in a recent issue of Nature Communications.
