US defense department says images of blinking triangular object in the sky and other UFOs were taken by navy personnel in 2019. Furthering the growing interest in unidentified flying objects, or what the US government refers to as unidentified aerial phenomena (UAP), the Department of Defense confirmed on Thursday that recently leaked photos and videos of UFOs were legitimate and taken by navy personnel. Sue Gough, a spokesperson for the Pentagon, confirmed to CNN that images and footage of a blinking triangular object in the sky, along with other UAPs that were categorized as a “sphere”, “aco ..read more

  In quantum physics, entangled particles remain connected so that actions performed on one affect the other, even when separated by great distances. The phenomenon so riled Albert Einstein he called it "spooky action at a distance." The rules of quantum physics state that an unobserved photon exists in all possible states simultaneously but, when observed or measured, exhibits only one state. Spin is depicted here as an axis of rotation, but actual particles do not rotate. Entanglement occurs when a pair of particles, such as photons, interact physically. A laser beam fired through a cer ..read more

This artist's illustration shows the evolution of the universe over time, starting with the Big Bang (left).(Image credit: NASA) Was the universe created with a Big Bang 13.7 billion years ago, or has it been expanding and contracting for eternity? A new paper, inspired by alternative explanations of the physics of black holes, explores the latter possibility, and rejects a core tenet of the Big Bang hypothesis.  The universal origin story known as the Big Bang postulates that, 13.7 billion years ago, our universe emerged from a singularity — a point of infinite density and gr ..read more

 The afterglow of the Big Bang reveals the geometry of the universe.   Einstein’s field equations describe gravity not as a force, but rather a property of space-time — the fabric of the universe. Earth travels around the Sun in a circular orbit because the Sun’s mass deforms the space-time around it like a bowling ball on a trampoline.   In ancient times, scholars such as Aristotle thought that heavy objects would fall faster than lightweight objects under the influence of gravity. About four and a half centuries ago, Galileo Galilei decided to test this assumption exp ..read more

  Artistic conception of gravitational waves. Public Domain Image, source: R. Hurt/Caltech-JPL.           Yes, gravity can forms waves. Gravitational waves are ripples in spacetime that travel through the universe. If you think of gravity as a force acting at a distance, it is difficult to visualize how gravitational waves could form. However, if you use the more accurate description of gravity that was developed by Einstein in his general theory of relativity, these concepts become more logical. General relativity describes gravity as a warping or curvat ..read more
