Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre ...

The slower growth of gravitational wells and the accelerating expansion might share the same underlying cause.” In so many ...

Gravity can exist without mass.” It’s a statement that upends a century of astrophysical dogma and, for some, sounds as plausible as finding a unicorn in a particle accelerator. But in a series of ...

That's not really wrong, but it is a little misleading. Actually, the gravitational potential energy for the Earth-person system would be defined as the following: Let's go over this new equation.

In this letter, we introduce an efficient and accurate high-order spectral-element approach for simulating 3-D gravity anomalies, including surface topography. This new method is based on the spectral ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what ...

Briefly, what does the research paper discuss? The paper demonstrates that high-precision optical corrections are essential to expanding our gravitational-wave view of the universe. It lays out the ...

Scientists have discovered that gravitational waves could turn neutron stars into cosmic tuning forks with characteristic reverberations that reveal their interiors.

That is, being close to the Earth does indeed give a smaller gravitational potential energy, which is the same relationship as with the equation for gravitational potential energy closer to the Earth.
