Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

This article covers the Punjab Board's 2025–2026 Class 11 Physics Syllabus. Class 11 students can download the syllabus in PDF format to become acquainted with the subjects that will be studied during ...

This black hole merger animation was created using data collected by the LIGO and Virgo gravitational wave detectors, an observation designated GW190412. Credits: © N. Fischer, H. Pfeiffer, A.

For decades, scientists have believed there should be black holes that fall between two well-known types. On one end are stellar-mass black holes, formed by collapsing stars, with masses between 5 and ...

It couldn’t be applied to accelerating (or non-inertial) objects or gravity. Equivalence principle This led Einstein to formulate the Equivalence Principle, a cornerstone of general relativity.

Measuring and reducing the stray potentials of space inertial sensors is of great significance for gravitational wave detection. Because of the actual configuration of inertial sensors, the optical ...

On Earth, we have to contend with our own gravity well when we launch rockets and spacecraft; if a rocket isn't powerful enough to escape its gravity well, it will fall back to Earth.

They detected gravity waves with near-inertial frequencies (NIGWs) in the lower stratosphere. ERA5, while able to qualitatively capture these NIGWs, underestimated their amplitude and failed to ...

The GRATTIS spacecraft in Earth orbit with two Gravitational Reference Sensors on board. The spacecraft serves as a test platform for next-generation inertial reference systems to track mass movement ...
