"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 ...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 ...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 ...How We Know Gravity is Not (Just) a Force

Instead gravity is an effect of the warping of space and time in the presence of mass. Without a force acting upon it ... the straight path of an object is bent when space and time is bent. This explains why all objects fall at the same rate.- 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.
