Taking a closer look at the age of Methuselah
For more than years, astronomers have been observing a curious star located some light years away from Earth in the constellation Libra. It rapidly journeys across the sky at , mph 1. But more interesting than that, HD — or Methuselah as it's commonly known — is also one of the universe's oldest known stars. In , scientists sought to date the star using observations via the European Space Agency's ESA Hipparcos satellite, which estimated an age of 16 billion years old. Such a figure was rather mind-blowing and also pretty baffling. As astronomer Howard Bond of Pennsylvania State University pointed out, the age of the universe — determined from observations of the cosmic microwave background — is Taken at face value, the star's predicted age raised a major problem. How could a star be older than the universe? Or, conversely, how could the universe be younger?
Taking a closer look at the age of the universe
Called primordial black holes, they were formed again in the hyper dense conditions existing in the moments after the, which would make them even more exotic and harder to understand than the supermassive black holes at the center of most galaxies. Professor Carr and Professor Coley say if the universe expands and contracts in cycles of big bangs and big crunches, some primordial black holes may survive. Again, this seems extremely interesting, but highly speculative. Dr Tamara Davis, an astrophysicist and theoretical cosmologist with the University of Queensland claims the same thing. She also makes a pretty convincing statement, explaining that the laws of physics change as the universe changes. So it becomes even more speculative to say black holes from one universe could exist in another. Andrei's background is in geophysics, and he's been fascinated by it ever since he was a child.
Scientists know this because they have estimated a property of its light known as the red shift, which is caused by the expansion of the Universe stretching the wavelengths of light emitted by the celestial object. XMM-Newton's data showed that iron was three times more abundant in the quasar than in our Solar System. Since iron is released by exploding stars, according to precise physical phenomena, and scientists think it builds up across the Universe gradually with time. The Solar System formed just 5 thousand million years ago, so it should contain more iron than the quasar, which formed over The fact that the quasar contains three times more iron than the Sun is therefore a major puzzle. One possible explanation is that something is wrong with the way astronomers measure the age of objects in the Universe.
