This mammoth explosion which created all the matter we see around us, was just the most recent of many. The standard big bang theory says the universe began with a massive explosion, but the new theory suggests it is a cyclic event that consists of repeating big bangs. ... It's saying there was time before the big bang."View full answer
People also ask, Is it possible there were multiple big bangs?
A 2020 Nobel Prize winner in physics named Sir Roger Penrose believes that the universe goes through cycles of death and rebirth. He believes that there have been multiple Big Bangs and that more will happen. Penrose points to black holes as holding clues to the existence of previous universes.
Subsequently, question is, How many times has Universe existed?. Our universe has existed for nearly 14 billion years, and as far as most people are concerned, the universe should continue to exist for billions of years more.
Hereof, 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. ... At least, not for another 3.7 billion years.
Will universe last forever?
This suggests that the universe began – very small and very dense – about 13.82 billion years ago, and it has expanded and (on average) become less dense ever since. ... There is a strong consensus among cosmologists that the shape of the universe is considered "flat" and will continue to expand forever.
The universe, being all there is, is infinitely big and has no edge, so there's no outside to even talk about. Oh, sure, there's an outside to our observable patch of the universe. The cosmos is only so old, and light only travels so fast. ... The current width of the observable universe is about 90 billion light-years.
They too will turn into black dwarfs. And so, in about 100 trillion years from now, every star in the Universe, large and small, will be a black dwarf. An inert chunk of matter with the mass of a star, but at the background temperature of the Universe. So now we have a Universe with no stars, only cold black dwarfs.
Many think it's likely you would just keep passing galaxies in every direction, forever. In that case, the universe would be infinite, with no end. ... Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
The simple answer is, "Yes, it is possible to stop time. All you need to do is travel at light speed." ... Special Relativity pertains specifically to light. The fundamental tenet is that light speed is constant in all inertial reference frames, hence the denotation of "c" in reference to light.
The Short Answer: Although humans can't hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. We all travel in time!
The universe is (nearly) 14 billion years old, astronomers confirm. With looming discrepancies about the true age of the universe, scientists have taken a fresh look at the observable (expanding) universe and have estimated that it is 13.77 billion years old (plus or minus 40 million years).
