Can the EHT M87 results be used to test general relativity?

چکیده

No. All theoretical predictions for the observational appearance of an accreting supermassive black hole, as measured interferometrically by a sparse Earth-sized array at current observation frequencies, are sensitive to many untested assumptions about accretion flow and emission physics. There is no way distinguish violation general relativity from much more likely scenario that relevant ``gastrophysical'' simply do not hold. Tests will become possible with longer interferometric baselines (likely requiring space mission) reach resolution where astrophysics-independent theory observable.

Can the Red-Green Duochrome Test Be Used Prior to Correcting the Refractive Cylinder Component?

PURPOSE A primary task of the eye care professional is determining the refraction, or optical correction, of a patient. The duochrome red-green test is a standard tool for verification of the final refraction. Traditionally, it is recommended for use both prior to and subsequent to determining the cylindrical or astigmatic component of the refraction. In order for it to be effective when used b...

How traditional symbols can be used as inspiration source in shaping the urban architecture?

This paper explores the developing of how designers can search for inspiration source which provided in the form of traditional elements and archetypes and also their role on idea generation in design from building to urban measure.
