Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.
As dark matter is comprised of particles that do not absorb, emit or reflect light, it cannot be observed directly with the methods used to observe conventional matter. In recent years, astrophysicists worldwide have thus ...
Charged cosmic rays, high-energy clusters of particles moving through space, were first described in 1912 by physicist Victor Hess. Since their discovery, they have been the topic of numerous astrophysics studies aimed at ...
Dark matter, matter in the universe that does not emit, absorb or reflect light, cannot be directly detected using conventional telescopes or other imaging technologies. Astrophysicists have thus been trying to identify alternative ...
Astrophysicists have been trying to understand the formation of cosmological objects and phenomena in the universe for decades. Past theoretical studies suggest that quantum fluctuations in the early universe, known as primordial ...
Black holes are astronomical objects with extremely strong gravitational pulls from which not even light can escape. While the idea of bodies that would trap light has been around since the 18th century, the first direct ...
The existence of dark matter remains one of the greatest mysteries of the universe. While studies have indirectly hinted at its existence, its invisible nature makes this elusive substance very difficult to detect, thus its ...
Past physics theories introduced several fundamental constants, including Newton's constant G, which quantifies the strength of the gravitational interaction between two massive objects. Combined, these fundamental constants ...
An open question among the physics community is whether black holes can be tidally deformed by an external gravitational field. If this were confirmed to be true, it could have important implications for many areas of physics, ...
Planet Earth is surrounded by a system of magnetic fields known as the magnetosphere. This vast, comet-shaped system deflects charged particles coming from the sun, shielding our planet from harmful particle radiation and ...
