Oldest Star Discovered, Could Bring An End To The Big-Bang Discrepancy

According to the Big-Bang hypothesis, the universe originated 13.7 billion years ago from the cataclysmic explosion of matter at extremely high density and temperature.

According to the Big-Bang hypothesis, the universe originated 13.7 billion years ago from the cataclysmic explosion of matter at extremely high density and temperature. Discrepancy arises when the European-led research team release all-sky map of the cosmic microwave background during the Planck cosmology investigation that comes to the conclusion that the universe is 13.798±0.037 billion years old, which is slightly older than we thought.

Eventually, this discrepancy maybe resolved as Australian astronomers claim to have discovered the oldest known star in the universe which is about 13.6 billion years old.

Oldest Star Discovered, Could Bring An End To The Big-Bang Discrepancy

The star, designated SMSS J031300.36−670839.3, is believed to have formed some hundred million years after the Big-Bang. The star has a unique chemical fingerprint showing it contained almost no iron.

Stefan Keller, lead researcher at the Australian National University Research School of Astronomy and Astrophysics says the stars that formed immediately after the big bang contained primordial mix of hydrogen, helium and a small amount of lithium. They are hundreds of times the mass of the Sun.

This newly discovered stars was formed during the event of a primordial star formation. It was believed that primordial stars died in an extremely violent explosion that contaminated the major portions of the space with iron, but the ancient star did with lighter elements such as carbon and magnesium and absolutely no sign of iron.

The star is situated in the outskirts of the Milky Way at a distance of around 6000 lights years from Earth, and  was discovered using the Australian National University’s SkyMapper telescope.

  1. This was very interesting. Thanks for posting. I wrote something merely philosophical on the idea of expansion not too long ago. But science is advancing at such a rapid pace that it’s making our ever changing perception of reality the new driving force behind evolution. Great post.

    1. Exactly! With this pace, super human strengths, travelling to space, all those things we watch in movies might not take that long to become a reality. Let’s see where science takes us. Thanks for the comment! 🙂

  2. Along with this huge and ancient cosmic evolution, which is the probability that within a galaxy like the milky way, from the dust of its exploded stars, the living being who uses a computer was formed – computer included? A favourable case among infinite unfavourable possibilities? Fifty-fifty? To be or not to be, is that the question? Or is it a zero followed by a radix point and an infinite amount of zeros behind, but finishing with a one emerging from error or compassion when rounding up? Are calculations simplified or made more complex when the subjective self of each one is the entity that is studied? Anyway, what is the relationship between life and immense numbers? Is life a folding process of infinity? That is, is it just something infinite that would have enough to allow a self, something isolated but of infinite claims? But, is infinity credible within something with a beginning, out of a Big Bang? And is it credible within something with an ending, with the inevitable death around the corner? Along these lines, there is a peculiar book, a preview in http://goo.gl/rfVqw6 Just another mind leisure suggestion, far away from dogmas or axioms.

  3. Oh, it’s always the same: no sooner have we all become convinced that drinking wine is bad for us, someone proves it’s good for us. Same here.

    1. That’s actually a good thing, it means we are improving, the standards of our lives are improving and actually the most amazing thing about science is that unlike other stuffs (Religious Dogmas, for example) science never stops improving. Scientists admit when they are wrong or when in doubt! Well, making mistakes is what a person learns from, right? 🙂

      1. Couldn’t agree more! If all those bloody religions disappeared overnight, though, we wouldn’t actually need so many of the astounding things people have invented,eh? LONG LIVE SCIENCE, says this dedicated atheist. 🙂

      2. Yes, you are right, religion is actually hindering the development (take the example of polio vaccine, in a Muslim country (Pakistan) – they would not let children get vaccinated against polio because somehow it’s against their beliefs), the rest of world is free of polio virus than Pakistan. Anyway, I recently read as the standards of lives are improving so is the number of Atheists, eventually everyone’s gonna be an atheist ’cause there is nothing more convincing than Atheism (for the brainy people, at least).:)

      3. But my dear! – just think of the squillions of morons who abound. People like our Aussies who drink beer with the deliberate intention of getting drunk … Alas, they’re all over the world.
