Bubble of Spacetime –“A ‘Time Machine’ That Moves Greater Than Speed of Light Allowing It to Travel Back and Forward in Time”

After some serious number crunching, a University of British Columbia researcher has come up with a mathematical model for a viable time machine –a bubble of space-time geometry which carries its contents backward and forwards through space and time as it tours a large circular path. The bubble moves through space-time at speeds greater than the speed of light at times, allowing it to move backward in time. Ben Tippett, a mathematics and physics instructor, whose field of expertise is Einstein's theory of general relativity, studies black holes and science fiction when he's not teaching. Using math and physics, he has created a formula that describes a method for time travel.

‘Cold Spot’ Anomaly Billions of Light Years Across –“Caused By a Collision With Another Universe”

Supervoid

 

"This means we can't entirely rule out that the Spot is caused by an unlikely fluctuation explained by the standard model. But if that isn't the answer, then there are more exotic explanations. Perhaps the most exciting of these is that the Cold Spot was caused by a collision between our universe and another bubble universe. If further, more detailed, analysis of CMB data proves this to be the case then the Cold Spot might be taken as the first evidence for the multiverse – and billions of other universes may exist like our own."

"This is the most exciting exoplanet which I have seen in the last ten years" comments Jason Dittmann of the Harvard-Smithsonian Centre for Astrophysics (CfA), the first author of the article in Nature. "It would be difficult to find a better objective for carrying out one of the most important searches in science: for evidence of life beyond the Earth".

The solar flux is considered the fundamental energy source of earth's climate system on long time scales. In recent decades, some studies have noted that the tiny variations in solar activity could be amplified by the nonlinear process in climate system. But the astronomy factors, such as solar activity, presented intriguing and cutting-edge questions to better understand climate change.

Thousands of people joined a global March for Science on Saturday with Washington the epicenter of a movement to fight against what many see as an "assault on facts" by populist politicians. The movement was echoed in hundreds of events across the United States and around the world, from Sydney to Accra. U.S. President Donald Trump himself passed dozens of protesters on his way to visit wounded soldiers at a military hospital. "Stop denying the earth is dying," one sign visible from Trump's motorcade read.
