Time Travel: New Research Suggests It’s Possible Without Paradoxes

Breaking News, Idea & Innovations, Learning & Developments, Space

The concept of time travel has long captivated the human imagination, inspiring countless films and theories. But a 2020 study led by Germain Tobar, a physics student at the University of Queensland, suggests that time travel could theoretically work without creating the infamous "grandfather paradox." This paradox challenges the logic of time travel: if someone went back in time and prevented their grandparents from meeting, their own existence and thus the possibility of time travel would be erased. However, Tobar's calculations indicate that the universe might naturally adapt to prevent such contradictions. For example, if a time traveler attempted to stop a disease from spreading, Tobar's research suggests the disease would still emerge through a different route, ensuring history...

Solar Surge Curtin University’s Binar Satellites Lost to High Solar Activity

Breaking News, Idea & Innovations, Space, Tech

Three Australian CubeSats from Curtin University's Binar Space Program recently burned up in Earth's atmosphere after only two months in orbit one-third of their expected mission duration. Named Binar-2, 3, and 4, these satellites were intended to last around six months in low Earth orbit but met an untimely end due to unexpected solar activity. In fact, “Binar” fittingly means “fireball” in Noongar, an Indigenous Australian language. Launched to gather scientific data and test new systems, the Binar satellites faced increased atmospheric drag caused by the Sun’s heightened activity. The Sun is currently in the peak phase of its 11-year solar cycle, known as solar cycle 25, during which solar flares, solar winds, and charged particles intensify. Recent solar indicators have shown activi...

Scientists Explore Diamonds in the Sky Could Nanoparticles Help Cool the Planet?

Breaking News, Idea & Innovations

Diamonds Heist movies are seldom about solving climate change, and for a good reason. Nobody wants to hear a voice murmur from the back seat as George Clooney tears down the highway with a dump truck full of stolen diamonds, "Hey, let's crush these sparkle-puppies into powder and scatter them through the stratosphere to cool the planet." However, a team of researchers, led by climate scientist Sandro Vattioni from ETH Zurich in Switzerland, have done the math on which materials would be most suitable for a stratospheric aerosol injection (SAI) method of global cooling, concluding that a few hundred trillion dollars' worth of diamond nanoparticles could be a viable solution. Before you start looking for a wise-cracking safe-cracker, a silent contortionist, and a wily femme fatale to c...
