**What is this page?**

This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.

It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.

If you're a ResearchGate member, you can follow this page to keep up with this author's work.

If you are this author, and you don't want us to display this page anymore, please let us know.

The unequal-vertical-distances theorem for gravitational fields is used to show that black holes cannot be plunged into effective finite time by astronauts. The reason is simple: The distance is effectively infinite. The new no-go result represents an anomaly in general relativity. (C) 2009 Physics Essays Publication. [DOI: 10.4006/1.3200899]

In searching for a potentially nonunique mapping between regions of high and low redshift, something simpler was found instead:
A proportional size increase in a high-redshift region. Unlike special-relativistic effects, where slowed-down (departing)
objects shrink in size, a size increase occurs in a gravitational potential. As the horizon of a bl...

The Gulliver effect is a vertical size change implicit in the equivalence principle. Unlike FitzGerald contraction, it can be both positive and negative. Moreover, it is reciprocal—while one party appears expanded to the other, the other appears contracted to the former: needle formation implies pancake formation and vice versa. Computer simulation...

Ives' identity which links the different gamma factors of special relativity can be used to show that Einstein's famous E=mc2 law is the quadratic (transverse) special case of a more general first-order longitudinal law E=mcv/2. The latter allows the conversion of energy into both positive and negative mass increments. It arises as an implication o...

... The latter is known to be very slow for large and mediumsized black hole masses [12]. Moreover, it was recently proposed that every locally stationary particle deep down in a gravitational well and close to the horizon suffers a mass decrease proportional to the local gravitational redshift factor [13]. If this were correct, a further mechanism beside Hawking evaporation would be needed in the present context. ...
