Are Newtonian Gravitation and Geometrized Newtonian Gravitation Theoretically Equivalent? [PDF]
, 2014 I argue that a criterion of theoretical equivalence due to Clark Glymour [Nous 11(3), 227-251 (1977)] does not capture an important sense in which two theories may be equivalent.

Tidskrift för Litteraturvetenskap, 2021 Gravitation: Modes of Reading in the Anthropocene In this article, I suggest ‘gravitation’ as a new way of reading in and for the anthropocene, which is characterised by environmentally destructive ‘social acceleration’.

ELGAR—a European Laboratory for Gravitation and Atom-interferometric Research [PDF]
Classical and quantum gravity, 2019 Gravitational waves (GWs) were observed for the first time in 2015, one century after Einstein predicted their existence. There is now growing interest to extend the detection bandwidth to low frequency.

The Gravitation of the Moon Plays Pivotal Roles in the Occurrence of the Acute Myocardial Infarction
Environmental Health Insights, 2008 Acute myocardial infarction (AMI) is a social burden. However, being able to predict AMI could lead to prevention. A previous study showed only the relation between the lunar phase and the occurrence of AMI, but the period it takes for the moon to orbit ...

Weak Deflection Angle and Shadow by Tidal Charged Black Hole
Universe, 2021 In this article, we calculate the deflection angle of a tidal charged black hole (TCBH) in weak field limits. First, we obtain the Gaussian optical curvature and then apply the Gauss–Bonnet theorem on it.

Modification of earth's gravity sphere [PDF]
Theoretical and Applied Mechanics, 2013 The standard radius of the Earth's gravity sphere is 917.000 km. Here we present that the radius is 1.400.000 km.

Scalar–Tensor–Vector Modified Gravity in Light of the Planck 2018 Data
Universe, 2021 The recent data release by the Planck satellite collaboration presents a renewed challenge for modified theories of gravitation. Such theories must be capable of reproducing the observed angular power spectrum of the cosmic microwave background radiation.

Irreversibility of time in general relativity [PDF]
Известия Саратовского университета. Новая серия: Физика, 2022 Background and Objectives: The equations of classical dynamics of particles and waves admit solutions with the reverse flow of time. Therefore, it is generally assumed that classical dynamics does not reflect the irreversibility of time.

The total mass of the early-type galaxy NGC 4649 (M60) [PDF]
Serbian Astronomical Journal, 2008 In this paper the problem of the total mass and the total mass-to-light ratio of the early-type galaxy NGC 4649 (M60) is analyzed. Use is made of two independent techniques: the X-ray methodology which is based on the temperature of the X-ray halo of NGC
