The Universe is huge. Because it is expanding and that expansion is accelerating, estimates have it stretching up to 93 billion light-years across, though the visible universe is only a mere 13.8 billion light-years across. This means most of the Universe will remain invisible, as its distant light has not had enough time to reach … Continued
For the first time, two neutron stars were directly observed colliding with one another and collapsing into a black hole. For astronomers, this discovery is a huge deal, because it hints at where most of the heavy metals in our Universe, such as silver, uranium, platinum and gold, come from.
Matter and antimatter should have destroyed each other in the moments after the Big Bang. That they didn’t is yet another enduring mystery of physics.
As an alternative to traditional funerals, a British company is launching ashes into space using rocket technology.
Physicists capture and measure elusive antimatter for the first time
Physicists may have discovered a fifth fundamental force of nature that could explain some of the mysteries surrounding dark matter.
[DIGEST: New Scientist, HubbleSite, IFLS] T.S. Eliot may have predicted the world ending “not with a bang, but a whimper,” but he may have missed the mark: the final destruction might be a tremendous rip. The good news is it won’t happen for at least 2.8 billion years, and it’s possible it will never happen … Continued
Einstein’s theory of relativity has survived over a hundred years, having been put to rigorous testing and come out unscathed. But recent conclusions on the accelerating expansion of the universe corroborate a further idea Einstein had posited–and rejected–nearly a century ago.
