TIME AND SPACE


“CAN YOU BUILD ME A HYPERBOLIC TIME CHAMBER?”

Almost 110 years ago our view of time was changed forever. Time wasn’t part of the immutable stage of life but it was an active player. We finally understood how to squeeze time and how to stretch it thanks to a German patent officer named Albert Einstein.
Einstein’s most famous thought experiment regarding time dilation is the Twin paradox. We have two twins, one goes into a spaceship that moves near the speed of light for a few hours and when he comes back to Earth, years have passed and his twin has aged significantly.


Where t is the proper time (in the twin paradox the time that passes on Earth) while t0 is the time for the moving observer.
Now let’s talk about the hyperbolic time chamber. In the Manga and Anime Dragon Ball Z there’s a special room where you can spend a year in there and only one day would have passed on Earth. My friend wants me to build him that, so let’s substitute our values in and see what we get.






As you can tell the equation doesn’t make sense we end up with an imaginary velocity. With what we know of physics so far we can’t make a hyperbolic time chamber (Zach Weinersmith is right – ‘Science: ruining everything since 1543’)
In our equation we assumed that we are not moving, but in reality we are – so what if I make sure my friend gets into a perfectly still space? If we combined the Earth’s motion around the Sun, the Sun’s motion around the centre of the Milky Way and the proper motion of our Galaxy (assuming these velocities are perpendicular to each other) our combined velocity is 360 km s-1. The Sun’s orbital speed around the Galaxy is 200 km/s. The speed of the Earth’s rotation is 0.27 km/s (1000 km/h) at the latitude of Sheffield (53 degrees), the average galaxy in a group moves at 300 km/s.
So we are constantly moving at about 0.1 % of the speed of light. When we use the formula to work out how much extra time he’d have if he spent an entire year inside my time chamber, the answer is not promising. Over an entire year he would have gained only 15 second on us. Better stick to an old fashion approach to time management.Image result for time and space

Stellar Nucleosynthesis

Image
Element Origins After the Big Bang, the ordinary matter in the Universe was composed primarily of just two elements: hydrogen and helium. Currently, there are a wide range of elements, from argon to zirconium. These more complex elements were nearly all produced via stellar evolution processes. The formation of new elements is called nucleosynthesis . Below,  I have describe the basics of the chemistry of the Universe and how it has changed over time. Big Bang Nucleosynthesis  The star-forming region 30 Doradus. The blue stars are massive, hot, young stars. They have formed in a cluster out of gas and dust. (Credit: NASA, ESA, HST WFC3) When the Big Bang occurred approximately 14 billion years ago, the Universe was very hot and dense. Over time, the Universe expanded and cooled down. Approximately 0.001 seconds after the Big Bang, particles (e.g., protons and neutrons) began to fuse together to form atomic nuclei, dubbed nuclear fusion . Nuclear fusion process

On the occasion of the inaugural ceremony of ATL, Astronomy club got a chance to showcase our skills and knowledge about space and space related sciences where we presented hydro rockets, live meteoroid composition , exoplanet weight composition and we gave other others a chance to use see through our MISO(our beloved telescope) which was modified with an inbuilt screen with various star gaze indicators.

Primordial Chill Hints at Dark Matter Interactions in Early Universe A simple experiment has detected a signal from the first stars forming just 180 million years after the Big Bang. The observations have intriguing implications for the nature of dark matter.   The first stars began to shine just 180 million years after the Big Bang , according to new observations by a team of American radio astronomers. The evidence comes from observations of neutral hydrogen gas that pervaded the early universe. But surprisingly, the same observations show an unexpected chill in this gas — a result that could hint at non-gravitational interactions with dark matter . “This is a really cool result,” says Michiel Brentjens (Netherlands Institute for Radio Astronomy), who was not involved in the study. “It’s an important first step in revealing how the very early universe behaved.” For years, astronomers like Brentjens have been trying to detect the early universe’s
