The above experiments search for a fifth force that is, like gravity, independent of the composition of an object, so all objects experience the force in proportion to their masses. Forces that depend on the composition of an object can be very sensitively tested by torsion balance experiments of a type invented by Loránd Eötvös.
The discovery could “completely change our understanding of the universe, with consequences for the unification of forces and dark matter.” Scientists believe they have discovered the fifth ...
The fifth dimension is difficult to directly observe, though the Large Hadron Collider provides an opportunity to record indirect evidence of its existence. [1] Physicists theorize that collisions of subatomic particles in turn produce new particles as a result of the collision, including a graviton that escapes from the fourth dimension, or ...
Downward acting weight force = Upward-acting buoyancy force + Upward-acting fluid drag force [4] where: π is the ratio of a circle's circumference to its diameter. R is the radius of the spherical object (in m), ρ is the mass density of the fluid (kg/m 3), g is the gravitational acceleration (m/s 2), C d is the drag coefficient, and

Researchers may be on the brink of discovering evidence of a fifth fundamental force. As far as we know, at the most basic level, the universe is made up of fundamental particles and controlled by ...
The name comes from quinta essentia (fifth element). So called in Latin starting from the Middle Ages, this was the (first) element added by Aristotle to the other four ancient classical elements because he thought it was the essence of the celestial world. Aristotle posited it to be a pure, fine, and primigenial element.
Of the many forces discussed above, tidal force is still highly debated and defended as a possible principal driving force of plate tectonics. The other forces are only used in global geodynamic models not using plate tectonics concepts (therefore beyond the discussions treated in this section) or proposed as minor modulations within the ...
