What is older than the universe?
Called the Methuselah star, HD 140283 is 190.1 light-years away.
Astronomers refined the star’s age to about 14.3 billion years (which is older than the universe), plus or minus 800 million years.

How old is our galaxy?
13.51 billion yearsMilky Way/Age
How long will the universe last?
Assuming that dark energy continues to make the universe expand at an accelerating rate, in about 150 billion years all galaxies outside the Local Supercluster will pass behind the cosmological horizon.
What is the brightest thing in the universe?
The brightest object in the universe has been discovered, a quasar from when the universe was just 7 percent of its current age. The quasar, now known as PSO J352. 4034-15.3373 (P352-15 for short), was discovered 13 billion light-years away from Earth by the Very Long Baseline Array (VLBA) radio telescope.
Can the universe end?
Theories about the end of the universe. The fate of the universe is determined by its density. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the “Big Freeze” scenario below.
What is the hardest thing in the universe?
The Hardest Known Substance In the Universe Is Something Called “Nuclear Pasta”
Will our Sun become a black hole?
Will the Sun become a black hole? No, it’s too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole. … In some 6 billion years it will end up as a white dwarf — a small, dense remnant of a star that glows from leftover heat.
What is the most expensive thing in the universe?
An astroid named 16 Psyche, after Cupid’s wife, was found to be made almost entirely of iron and nickel. That means, in current US markets, 16 Psyche is worth somewhere around $10,000 quadrillion (the world’s economy is around $74 trillion).
What is the biggest thing in the universe?
The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure. For perspective, the universe is only 13.8 billion years old.
What is the most powerful thing in the universe?
That’s about the same amount of energy in 10 trillion trillion billion megaton bombs! These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe.
Will we ever travel to other galaxies?
According to our current understanding of physics, an object within space-time cannot exceed the speed of light, which means an attempt to travel to any other galaxy would be a journey of millions of earth years via conventional flight.
Does time have an end?
“Time is unlikely to end in our lifetime, but there is a 50% chance that time will end within the next 3.7 billion years,” they say. That’s not so long! It means that the end of the time is likely to happen within the lifetime of the Earth and the Sun. But Buosso and co have some comforting news too.
What will happen in 100 trillion years?
100 Trillion Years – The Universe Dies This is the point at which the universe would reach a maximum state of entropy. Any stars that remain will continue to slowly burn away until the last star is extinguished. Instead of fiery cradles, galaxies will become coffins filled with remnants of dead stars.
