What are you thinking About Bubble? Do you like bubbles. Ever feel like you live in a bubble? Some body saying we already living in the bubbles. Is it small bubble or large bubble,I don't know. But University of Chicago know about this, It's called the "Local Bubble" or "local hot bubble"  Scientists have proposed a new method for the formation of our Solar System 4.6 billion years ago, suggesting it was born from a giant star shedding its layers rather than a supernova. Published in the  Astrophysical Journal , a study from the University of Chicago points towards a Wolf-Rayet star as the possible progenitor of our own Sun. These are some of the  most massive and brightest  stars in the universe. The general prevailing theory is that our solar system formed billions of years ago near a supernova. But the new scenario is different from all others, instead begins with a giant type of star called a Wolf- Rayet star, which is more than 40 to 50 times...

Galileo’s most famous experiment has taken a trip to outer space. The result? Einstein was right yet again. The experiment confirms a tenet of Einstein’s theory of gravity with greater precision than ever before. According to science lore, Galileo dropped two balls from the Leaning Tower of Pisa to show that they fell at the same rate no matter their composition. Although it seems unlikely that Galileo actually carried out this experiment, scientists have performed a similar, but much more sensitive experiment in a satellite orbiting Earth. Two hollow cylinders within the satellite  fell at the same rate over 120 orbits , or about eight days’ worth of free-fall time, researchers with the MICROSCOPE experiment report December 4 in  Physical Review Letters . The cylinders’ accelerations match within two-trillionths of a percent. The result confirms a foundation of Einstein’s general theory of relativity known as the equivalence principle. That pri...
