physicists just e up with a mathematical model for a viable time machine

physicists just e up with a mathematical model for a viable time machine "mathematically, it is possible." bec crew 28 apr 2017 physicists have come up with what they claim is a mathematical model of a theoretical "time machine" - a box that can move backwards and forwards through time and space. the trick, they say, is to use the curvature of space-time in the universe to bend time into a circle for hypothetical p engers sitting in the box, and that circle allows them to skip into the future and the past. "people think of time travel as something as fiction. and we tend to think it's not possible because we don't actually do it," says theoretical physicist and mathematician, ben tippett, from the university of british columbia in canada. "but, mathematically, it is possible." together with david tsang, an astrophysicist at the university of maryland, tippett has used einstein's theory of general relativity to come up with a mathematical model of what they're calling a traversable acausal retrograde domain in space-time (yep, the acronym is literally tardis). but before we get into the madness of legit time travel, let's put this into perspective real quick - the researchers aren't claiming to have a blueprint for a doctor who-style time machine that can be built tomorrow. they say the materials we'd need to build this thing are so exotic, we haven't even discovered them yet... but we'll get to that in a minute. firstly, let's talk about what tippett and tsang are actually proposing. the model is based on the idea that instead of looking at the universe in three spatial dimensions, with the fourth dimension (time) separated, we should be imagining those four dimensions simultaneously. that allows us to consider the possibility of a space-time continuum, where different ... ادامه ...

study sheds new insights into global warming trends

a new multi-institutional study of the temporary slowdown in the global average surface temperature warming trend observed between 1998 and 2013 concludes the phenomenon represented a redistribution of energy within the earth system, with earth's ocean absorbing the extra heat. the phenomenon was referred to by some as the "global warming hiatus." global average surface temperature, measured by ellites and direct observations, is considered a key indicator of climate change. in a paper published today in earth's future, a journal of the american geophysical union, lead author xiao-hai yan of the university of delaware, newark, along with scientists from nasa's jet propulsion laboratory, pasadena, california, and several other institutions, discuss new understanding of the phenomenon. the paper grew out of a special u.s. climate variability and predictability program (clivar) panel session at the 2015 american geophysical union fall meeting. "the hiatus period gives scientists an opportunity to understand uncertainties in how climate systems are measured, as well as to fill in the gap in what scientists know," said yan. "nasa's examination of ocean observations has provided its own unique contribution to our knowledge of decadal climate trends and global warming," said study co-author veronica nieves of jpl and the university of california, los angeles. "scientists have more confidence now that earth's ocean has continued to warm continuously through time. but the rate of global surface warming can fluctuate due to natural variations in the climate system over periods of a decade or so." where's the missing heat? while yan said it's difficult to reach complete consensus on such a complex topic, a thorough review of the literature and much discussion and debate revealed a ... ادامه ...
