Physicists have used a quantum computer to simulate the first-ever holographic wormhole and transport information through it. The “baby” wormhole, created on Google’s Sycamore 2 quantum computer was not created with gravity, but through quantum entanglement — the linking of two particles such that measuring one instantaneously affects the other. By entangling qubits, or quantum … Read more
Astronomers estimate that roughly 85% of all the matter in the universe is dark matter, meaning only 15% of all matter is normal matter. Accounting for dark energy, the name astronomers give to the accelerated expansion of the universe, dark matter makes up roughly 27% of all the mass energy in the cosmos, according to … Read more
Scientists have just announced a breakthrough in nuclear fusion ignition: For the first time the heart of a powerful fusion reactor has briefly generated more energy than was put into it. But experts are urging caution, saying that the breakthrough, while hugely significant, is still a long way from safe, limitless nuclear energy. On Tuesday (Dec. 13), physicists at … Read more
The universe may seem shapeless because it is so vast, but it does have a form that astronomers can observe. So, what is it shaped like? Physicists think the universe is flat. Several lines of evidence point to this flat universe: light left over from the Big Bang, the rate of expansion of the universe … Read more
Researchers studying the aftermath of a gargantuan black hole collision may have confirmed a gravitational phenomenon predicted by Albert Einstein a century ago. According to new research published today (Oct. 12) in the journal Nature (opens in new tab), the phenomenon — which is known as precession and is similar to the wobbling motion sometimes … Read more
By firing a Fibonacci laser pulse at atoms inside a quantum computer, physicists have created a completely new, strange phase of matter that behaves as if it has two dimensions of time. The new phase of matter, created by using lasers to rhythmically jiggle a strand of 10 ytterbium ions, enables scientists to store information … Read more
Gigantic deserts of almost complete nothingness that make up most of the universe may be causing the expansion of the universe to speed up, new research suggests. That means these vast tracts of nothingness could explain dark energy, the mysterious force that seems to be flinging the universe apart. Welcome to the desert Zoom all … Read more
Physicists have created a system of two connected time crystals, which are strange quantum systems that are stuck in an endless loop to which the normal laws of thermodynamics do not apply. By connecting two time crystals together, the physicists hope to use the technology to eventually build a new kind of quantum computer. “It … Read more
So far no one has found evidence of intelligent aliens elsewhere in the cosmos. But if they do exist, they might be hanging out on Dyson spheres circling the husks of sunlike stars called white dwarfs scattered throughout the Milky Way, a new paper argues. And that’s there we should be focusing our search for … Read more
A new warp speed experiment could finally offer an indirect test of famed physicist Stephen Hawking’s most famous prediction about black holes. The new proposal suggests that, by nudging an atom to become invisible, scientists could catch a glimpse of the ethereal quantum glow that envelops objects traveling at close to the speed of light. … Read more
