One of the most impressive things accomplished in the 20th century was Einstein's Theory of Relativity. What we perceive as the force of gravity is actually a result of the curvature of space and time.
According to Space.com, 'Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity.'
Elasticity is a very simple concept in both economics and physics. In physics, it's all about an object - like a rubber band or your mouth - going back to its original shape after its stretched. Demand works similarly.
I just finished watching the new film Hidden Figures. It is about physicist and mathematician, Katherine Johnson as well as mathematician Dorothy Vaughan and engineer Mary Jackson, all of whom worked for NASA. It's about time these women got some recognition for their accomplishments.
According to the Internet, Gravitational waves 'are distortions in the fabric of space and time'. So does that mean there really could be parallel universes? And wouldn't that also mean that you could, in theory...
