"An Unknown Force of the Universe is Acting on Dark Matter"

Zhao suggested that an unknown force is acting on dark matter. Only 4% of the universe is made of known material. Stars and gas in galaxies move so fast that astronomers have speculated that the gravity from a hypothetical invisible halo of dark matter is ...Here’s what ‘Gravity’ gets right and wrong about space

Isaac Newton tells us that an object in motion will remain in motion unless acted upon by an outside force. Kowalski was unable to arrest his forward movement by grabbing ahold of the ISS, so he goes floating off into space. Other than gravity, which we ...The physics of that gravity-defying chain of metal beads

How does a seemingly unremarkable chain of metal beads somehow appear to defy gravity? The physics nerd in me had to find out ... Mathematically, momentum is just the product of an object’s mass and its velocity. momentum = mass x velocity Or, as ...Thinking about the physics of mountain biking

For example the force ... objects to come together. In mountain biking, the tires are attracted, or pulled downwards, to the ground. Gravity is the force behind this attraction; gravity melds rubber to soil. Traction, another force, is the tendency for an ...- Gravity is the force that attracts ... It is what causes objects to have weight. When you weigh yourself, the scale tells you how much gravity is acting on your body. The formula for determining weight is: weight equals mass times gravity.
