Abstract Gravity and space-time are relative to each other because gravity or more precisely a gravitational wave is the only candidate responsible for empty-space around a mass and empty-space is the only candidate responsible for the mass of an object. It is true that a gravitational wave is a ripple in space-time but space-time is a result of a web of gravitational waves is also true and hence it is more appropriate to call space-time as gravitational-space-time and its known word to us is empty-space. Smallest unit of this web of gravitational waves is known as kaushal constant (K) [1]. Gravity is a result of the force of attraction in between two adjacent kaushal constants of the adjacent planes at a relative point in gravitational-space-time and hence this can be nicknamed as a web of gravity. The slower you move through space, the smaller your gravity web (or weaker the relative gravity) and hence the faster you move through time and vice versa. This paper is a solution to both mathematical and theoretical problems encountered in the field of quantum gravity [2] using theory of special connectivity [3].

Thermal conductive polymer composites (filled type) consisting of thermal conductive fillers and a polymer matrix have been widely used in a range of areas. More than 10 strategies have been developed to improve the thermal conductivity of polymer composites. Here we report a new “hypergravity accumulation” strategy. Raw material mixtures of boron nitride/silicone rubber composites were treated in hypergravity fields (800–20,000 g, relative gravity acceleration) before heat-curing. A series of comparison studies were made. It was found that hypergravity treatments could efficiently improve the microstructures and thermal conductivity of the composites. When the hypergravity was about 20,000 g (relative gravity acceleration), the obtained spherical boron nitride/silicone rubber composites had highly compacted microstructures and high and isotropic thermal conductivity. The highest thermal conductivity reached 4.0 W/mK. Thermal interface application study showed that the composites could help to decrease the temperature on a light-emitting diode (LED) chip by 5 °C. The mechanism of the improved microstructure increased thermal conductivity, and the high viscosity problem in the preparation of boron nitride/silicone rubber composites, and the advantages and disadvantages of the hypergravity accumulation strategy, were discussed. Overall, this work has provided a new, efficient, and simple strategy to improve the thermal conductivity of boron nitride/silicone rubber and other polymer composites (filled type).
