“The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood ...

Scientists have proposed a way that the universe could stop expanding, ending in a 'Big Crunch' that resets space and time as we know it. When you purchase through links on our site, we may earn an ...

A new theory suggests our universe and a time-reversed twin could emerge together. This quantum approach avoids singularities and offers an explanation for dark energy. Traditional cosmological models ...

Einstein's general theory of relativity, published in 1915, relates spacetime curvature to matter distribution, leading to the Schwarzschild solution describing a black hole. The Schwarzschild ...

The concept of time travel has always captured the imagination of physicists and laypersons alike. But is it really possible? Of course it is. We’re doing it right now, aren’t we? We are all traveling ...

IN cosmology a continuous fluid is used to represent the complex contents of the universe. Homogeneous and isotropic models then show that the universe originated from a space–time singularity of ...

We all survey the vastness of space with a certain amount of wonder and awe. Exploring and understanding the cosmos requires units to express its size — including volume. But because of that vastness, ...
