Time travel has long been dismissed as impossible due in part to the infamous “grandfather paradox.” This conundrum asks what would happen if someone traveled back in time and prevented their grandfather from having children, thus erasing the traveler’s existence. However, a new study may have resolved this issue. By combining general relativity, quantum mechanics, … Read more
Quantum physicists are familiar with wonky, seemingly nonsensical phenomena: atoms and molecules sometimes act as particles, sometimes as waves; particles can be connected to one another by a “spooky action at a distance,” even over great distances; and quantum objects can detach themselves from their properties like the Cheshire Cat from Alice’s Adventures in Wonderland … Read more
Astronomers have peered back to the dawn of the cosmos to observe time ticking five times more slowly in the early universe than it does now — finally proving a prediction that Albert Einstein made more than a century ago. Researchers spotted the extreme slow-motion effect in data taken from bright cosmic beacons known as … Read more
Ripples in space-time known as gravitational waves could help reveal the secrets at the dawn of time, just moments after the Big Bang, new research suggests. And physicists say they can learn more about these primeval gravitational waves using nuclear fusion reactors here on Earth. In a new study, physicists used equations that govern how … 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
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
Does time exist? The answer to this question may seem obvious: Of course it does! Just look at a calendar or a clock. But developments in physics suggest the non-existence of time is an open possibility, and one that we should take seriously. How can that be, and what would it mean? It’ll take a … Read more
Time is the apparent progression of events from past to future. While it’s impossible to completely define the nature of time, we all share many common experiences bound by time: Causes lead naturally to effects, we remember the past but not the future and the evolution of time appears to be continuous and irreversible. Einstein’s … Read more

Today: Time dilation refers to the seemingly odd fact that time passes at different rates for different observers, depending on their relative motion … Read more
M. Timothy Murray has a new space opera out: Time Paradox. And there’s a giveaway! The time crew are unexpectedly thrust six hundred years into Thumar’s past, where a planet wide plague is raging. These intrepid time travelers are predestined to find a cure. When they return to the future, they discover their actions dramatically … Read more
