Nikola Tesla Anti gravity
But Tesla didn’t stop there, he was into the incredible secrets of flight and antigravity which led him to register a patent in 1928, number 1, 655, 144 for a flying machine that resembled both a helicopter and an airplane. Before his death, Tesla had developed the blueprints for the propulsion system…
Earths gravitational field
Though it seems hard to believe, Earth’s gravitational pull is not the same everywhere you go. And as these gorgeously detailed maps now show, these variances are much greater than we thought. Top image: The low gravity atop Mount Everest (credit: GGMplus/Curtin University). Gravity varies on our planet…
What is the Dark energy?
So what is dark energy? Well, the simple answer is that we don t know. It seems to contradict many of our understandings about the way the universe works. We all know that light waves, also called radiation, carry energy. You feel that energy the moment you step outside on a hot summer day. Einstein…

Gravitational attraction between Earth and Moon
Gravity or gravitational forces are forces of attraction. We re not talking about finding someone really cute and adorable. It s like the Earth pulling on you and keeping you on the ground. That pull is gravity at work. Every object in the universe that has mass exerts a gravitational pull, or force…
Scientific Meaning of law
Definitions of Fact, Theory, and Law in Scientific Work Science uses specialized terms that have different meanings than everyday usage. These definitions correspond to the way scientists typically use these terms in the context of their work. Note, especially, that the meaning of “theory” in science is different than the meaning of “theory” in everyday conversation. Fact:…

Gravitational force planets
Gravity is a natural occurrence in which physical objects are attracted toward one another. This attraction is proportional to the objects’ masses. Since the mass of each planet is different, the gravitational pull on an object will be different on each planet as well. Hence, an individual’s weight would vary depending on what planet they are on. Below is a list of the gravitational…

Universal Gravitation Definition
An artist s rendering of some of the forces of the universe. The apple falling is of course from the story of Isaac Newton discovering the law of gravity as an apple fell from a tree he was sitting underneath. Windows to the Universe original image Related links: Gravity is one of the universal forces of nature. It is an attractive force between all matter, and is very weak…

What causes gravitational pull?
Editor s Note: We asked several scientists from various fields what they thought were the greatest mysteries today, and then we added a few that were on our minds, too. This article is one of 15 in LiveScience s Greatest Mysteries series running each weekday. In the deepest depths of space, gravity tugs on matter to form galaxies, stars, black holes and the like. In spite…
