Is anything older than the Big Bang?
By combining the luminosity and spectral information with advanced models of star formation and evolution, the researchers estimated an age on the Methuselah Star of 14.46 ± 0.8 billion years, older than the accepted 13.799 billion year lifetime of the universe.
So what is the difference? The first clear difference is that the Big Bang singularity of the FRW models lies in the past of all events in the universe, whereas the singularity of a black hole lies in the future. The Big Bang is therefore more like a “white hole”: the time-reversed version of a black hole.
Which came first galaxies or black holes?
It’s not understood yet whether a black hole or a galaxy came first. In recent observations, a super-massive black hole was discovered in an early-stage small galaxy.
How old is the oldest quasar?
This quasar in particular, named P172+18, is a relic from around 780 million years after the Big Bang and reveals clues about one of the earliest ages of the universe — the epoch of reionization.
Is there anything older than the universe?
HD 140283 (or the Methuselah star) is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy.
Will there ever be a black hole in our solar system?
Planet nine might be a primordial black hole The closest confirmed black hole to Earth lies in a triple-star system called HR 6819, roughly 1,000 light-years away. It’s about four times the mass of the sun — comparatively light in the scope of the universe.
How far is the farthest black hole from Earth?
This black hole is 1,500 light years away from Earth, still inside the Milky Way galaxy.
What is the most oldest thing in the universe?
GRB 090423
GRB 090423 was also the oldest known object in the Universe, apart from the methuselah star. As the light from the burst took approximately 13 billion years to reach Earth.
