‘It's so silly': Study reveals how long the universe has left until the ‘Big Crunch' occurs
According to a new study, researchers predict the universe only has 20 billion years left before what's been dubbed the 'Big Crunch' will occur. Sky News host Freya Leach discussed the study's findings. 'It's so silly – I mean the Earth, according to this article, has been around for 13.8 billion years, so we're not even halfway through Earth's life cycle, so you hear people stressing about the end of the world,' she said. 'It's ok, guys. We've got another 20 billion years.'

Universe 'death date' is a lot sooner than thought
The end of the universe will happen far sooner than thought. A team of scientists from the US and China have established that the universe will reach its 'death date' and no longer expand once it turns 33.3 billion years old. As the universe is estimated to be 13.8 billion years old at present, it leaves just over 19 billion years to go before everything ends in what boffins describe as a 'Big Crunch'. Experts at New York's Cornell University and Shanghai's Jiao Tong University have created a new cosmic model that suggests that dark energy - the force believed to be responsible for the universe's expansion - will weaken over time and ultimately succumb to gravity. Scientists are still attempting to prove that dark energy actually exists but the theory contradicts previous ideas that the universe could continue indefinitely. NASA's Chelsea Gohd said: "What exactly is dark energy? The short answer is: We don't know. But we do know that it exists, it's making the universe expand at an accelerating rate, and approximately 68.3 to 70 per cent of the universe is dark energy."

'Death date' of the universe unveiled as scientists say clock ticking for Earth
Physicists from Cornell University and Shanghai Jiao Tong University have detailed how the universe will come to an end and how it will be like a 'reverse Big Bang' A 'death date' for the universe has been revealed as a new study has claimed that the universe will begin to shrink seven billion years from now. Scientists have stated that the clock is ticking for planet Earth after it reached its peak size, and things will start to contract until 'everything collapses back into a single point'. The theory has just been published by physicists from Cornell University and Shanghai Jiao Tong University. The catastrophic event has been dubbed the Big Crunch - and likened to a reverse Big Bang. They studied data from various astronomical surveys including the Dark Energy Survey and the Dark Energy Spectroscopic Instrument. But it seems the universe will take quite some time to shrink. The so called Big Crunch will take place in approximately 34 billion years, so there's plenty of time to get your affairs in order. But anyone still around by that point faces a tricky time - the universe will expand like a "rubber band", they outline, causing everything to "snap back together". According to other research, there could be nobody left to experience it. Earth will be "engulfed by our dying sun" in approximately seven billion years. But Sir Isaac Newton predicted we've got not much time left at all - he said the world will end in 2060 in a chilling letter scrawled above a maths calculation more than 300 years ago. The renowned scientist, who discovered gravity and invented calculus, wrote about a second coming of Christ in just over four decades time - marking an end to life as we know it in 2060. Newton wrote this ominous warning on a letter slip in 1704. Born in 1643, Newton was considered an insightful theologian who had a life-long interest in the existence of God and religion. He based a lot of his religious writings on his readings of the Bible and believed in biblical visions of the Apocalypse — especially the Battle of Armageddon. Writing under the alias 'Jehovah Sanctus Unus' predicted the world would "reset" at 2060 at which point the Earth will once again become 'the Kingdom of God', the Daily Mail reports. Newton wrote: "So then the time times & half a time are 42 months or 1260 days or three years & an half, recconing twelve months to a yeare & 30 days to a month as was done in the Calendar of the primitive year. "And the days of short lived Beasts being put for the years of lived kingdoms, the period of 1260 days, if dated from the complete conquest of the three kings A.C. 800, will end A.C. 2060. It may end later, but I see no reason for its ending sooner." In another prediction referencing the date 2060, Newton stated: "This I mention not to assert when the time of the end shall be, but to put a stop to the rash conjectures of fanciful men who are frequently predicting the time of the end, [and] by doing so bring the sacred prophecies into discredit as often as their predictions fail. Christ comes as a thief in the night, [and] it is not for us to know the times [and] seasons [which] God hath put into his own breast."

New study claims the universe will start shrinking in 7 billion years

While some, like Robert Frost, have waxed poetic about the end of life on Earth—fire or ice—others have been looking to science to solve the mystery. Even still, others have been looking at the bigger picture, trying to figure out when the entire universe will end. Now, a new study claims that the universe itself might start shrinking within the next 7 billion years, leading to what scientists call 'the Big Crunch.' The study was published by physicists from Cornell University, Shanghai Jiao Tong University, and several other institutions. Using data collected from many different astronomical surveys, including the Dark Energy Survey, the researchers have created a new model that predicts our universe will end with what scientists have long theorized will be a 'Big Crunch.' The model suggests the universe will end roughly 33.3 billion years after the Big Bang.

So far, the universe is estimated to be around 13.8 billion years old. Based on that number and the model's prediction of when the universe will end, we have roughly 20 billion years before the universe collapses in on itself. This study, and the theory of the 'Big Crunch,' challenges long held assumptions that the universe will expand forever, eventually leading to a 'Big Freeze.' Instead, the researchers estimate that the universe will continue to expand for another 7 billion years. At that point, the universe will then begin contracting. Essentially, it will collapse in on itself until a single point remains, destroying everything. It's an interesting and somewhat terrifying theory, even if we aren't expecting it to happen in our lifetime. One easy way to think about it is to imagine the universe as a massive rubber band. As the universe expands, the rubber band stretches. But then it eventually reaches a point where it can't be stretched anymore, forcing the band to become stronger than its expansion force. This then causes everything to snap back together. It's a bit of a sad way for the universe to end, and I can't imagine what it would actually look like if there was any way to see it taking place. Luckily, it's not really something we have to worry about, and this research is far from actual confirmation that this is what will happen. For all we know, the theories could be incorrect, and the universe could indeed keep expanding forever.

Study reveals ‘death date' of the universe before ‘Big Crunch' occurs
Time to get your affairs in order — we only have 20 billion years left. That is according to researchers who have published a new study claiming that our once-believed ever-expanding universe will actually begin to shrink in seven billion years. The study, which was published by physicists from Cornell University, Shanghai Jiao Tong University, and other institutions, suggests that the universe will reach a peak size. After that point, the universe will begin contracting until everything collapses back into a single point. It's essentially a reverse Big Bang, which scientists have dubbed the 'Big Crunch'. Using data from a number of astronomical surveys including the Dark Energy Survey and the Dark Energy Spectroscopic Instrument, the researchers predict that this 'Big Crunch' will occur in approximately 33.3 billion years. With the universe currently 13.8 billion years old, this gives Earth and everything else roughly 20 billion years before entering oblivion, according to the study. And considering the Earth is expected to be engulfed by our dying sun in approximately seven billion years, it's probably not something anyone will have to worry about too much. The theory is that the universe expands like a 'rubber band' – eventually, the elastic force becomes stronger than the expansion, causing everything to snap back together. The researchers' theory hinges on dark energy, a mysterious force that makes up about 70 per cent of the known universe. Dark energy has long been believed to be the driving force behind the expansion of the universe. However, recent observations suggest the force might actually be dynamic – meaning it can only expand so much until it shrinks again. The new model proposed by researchers suggests the universe will continue expanding but at a gradually slowing rate. At its maximum size, about 69 per cent larger than the size it is today, a gradual contraction will begin. Several major astronomical projects launching in the coming years aim to provide more information on the behaviour of dark energy. These missions could confirm or rule out a 'Big Crunch' scenario. Even if the terrifying outcome is confirmed, a 20 billion year countdown is hardly a reason to panic. For context, complex life on Earth has existed for only about 600 million years – a fraction of time in comparison. 20 billion years down the line, the Sun will have died and our galaxy will have collided with the neighbouring Andromeda galaxy long before 'the great end'. The prediction also comes with a significant level of uncertainty. The researchers have acknowledged that their model has large margins of error due to limited observational data. So, alternative scenarios – including eternal expansion – are still possible.
