What came before the Big Bang? A trip through cosmology, multiverses, fifth dimensions and a big bounce
Where were you before you were conceived?
The question itself has no meaning: there was no “you” to be anywhere at all.
Asking questions like “what happened before the Big Bang?” is similarly meaningless.
Confused? You see, the birth of the Universe is not just the birth of subatomic particles and energy, it is also the beginning of time and space.
A Huge Experiment Has ‘Weighed’ the Tiny Neutrino, a Particle That Passes Right Through Matter
An experiment nearly two decades in the making has finally unveiled its measurements of the mass of the universe’s most abundant matter particle: the neutrino.
The neutrino could be the weirdest subatomic particle; though abundant, it requires some of the most sensitive detectors to observe. Scientists have been working for decades to figure out whether neutrinos have mass and if so, what that mass is. The Karlsruhe Tritium Neutrino (KATRIN) experiment in Germany has now revealed its first result constraining the maximum limit of that mass. The work has implications for our understanding of the entire cosmos, since these particles formed shortly after the Big Bang and helped shape the way structure formed in the early universe.
“You don’t get a lot of chances to measure a cosmological parameter that shaped the evolution of the universe in the laboratory,” Diana Parno, an assistant research professor at Carnegie Mellon University who works on the experiment, told Gizmodo.
Astronomers Found Goliath Pulsar That Can Collapse Forming A Black Hole
Researcher say this massive high speed Neutron star is at the edge to become a black hole.
Researchers discover massive neutron star that tests the limits of physics
Astronomers have detected the most massive neutron star ever, and it almost shouldn’t even exist.
Neutron stars are the smallest in the universe, with a diameter comparable to the size of a city like Chicago or Atlanta. They are the leftover remnants of supernovae. But they are incredibly dense, with masses bigger than that of our sun. So think of the sun, compressed into a major city.
In the case of the newly detected neutron star, dubbed J0740+6620, it’s 333,000 times the mass of the Earth and 2.17 times the mass of the sun. But the star is only about 15 miles across. It’s 4,600 light-years from Earth.
Like wine in a glass
Like wine in a glass, huge clouds of hot gas are sloshing back and forth in a cluster of galaxies about 480 million light years from Earth! Sloshing motions, like those seen here in Abell 2052, redistribute elements forged in supernova explosions such as iron and oxygen!

This invention relates to a spacecraft propulsion system utilizing thrusters comprised of a motor-driven electrostatically charged cylinder rotating within an electrostatically charged annular ring for the purpose of creating a spacetime curvature stress-energy tension in the horizontal direction. The thrusters are augmented by magnetic vortex generators, either embedded in the cylinders or located above each thruster, for the purpose of increasing the permittivity of space by permeating each thruster with low density hyperspace energy generated by a wormhole created between our space and hyperspace. A combination of three thrusters mounted on the underside of the hull of the spacecraft provide thrust and yaw motion control.
Gravitational waves detected for first time from newly born black hole: Study
Researchers have, for the first time, detected the gravitational waves from a newly born black hole, and found that the ringing pattern of the waves predicts the cosmic body’s mass and spin, providing more evidence for Einstein’s General Theory of Relativity.
The study, published in the journal Physical Review Letters, increases the possibility that black holes exhibit only three observable properties – mass, spin, and electric charge.
All other properties, the study noted, could be swallowed up by the black hole itself, and are unobservable.
