A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the ...
"We are able to measure the local dark matter density using direct acceleration measurements for the first time." ...
Everything experiences the same amount of gravity, but if you take a hammer in one hand and a feather in the other and drop them at the same time, the hammer will hit the ground first. Why? Drag (air ...
Ask almost any physicist what the most frustrating problem is in modern-day physics, and they will likely say the discrepancy between general relativity and quantum mechanics. That discrepancy has ...
Dark matter density in the Milky Way measured using pulsars Pulsar acceleration data reveals galactic gravitational mapping Study expands dark matter research beyond binary pulsars ...
Why? Drag (air resistance) opposes acceleration due to gravity. In a vacuum, such as on the Moon, both objects will hit the ground at the same time. Gravity applies an effective force of mutual ...
