Gravitational Radiation Amplitude: Inverse Square Law Explained

AI Thread Summary
Gravitational radiation is now widely accepted, with its amplitude calculable through established mathematical frameworks. The inverse square law applies to gravitational radiation amplitude because spherically symmetric radiation spreads its intensity over the surface of a sphere, which increases with the square of the radius. There is speculation about a potential fifth power effect influencing the inverse square law for gravity, which could have implications for theories involving extra dimensions. The EOT-WASH group has conducted tests in the millimeter range to explore this effect, though the conclusiveness of these tests remains uncertain. Understanding these principles is crucial for advancing theories in gravitational physics.

gravitational radiation is now widely accepted, and the mathematical
outcome of an events radiation is calculable, but why is the inverse
square law applicable to the amplitude of this radiation?
 
Science news on Phys.org
Anything that is spherically symmetric will obey the inverse square law as when it is moving from the centre of origin it is spreading its intensity over the surface of a larger sphere and as we know the surface of the sphere is related to its radius squared.
 
i must be careful here as i don't have the facts in front of me.
i read some time ago that a 5TH power may have a short range
effect on the ISl for gravity, and if this effect is not found then
certain, "extra dimensions" theories can be ruled out, i think the
EOT-WASH group have done tests in the mm range, but I am not
sure if these tests are conclusive.
 

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
