Meet the Big Crunch: In this theory on the origins of the universe, the Big Bang was not the beginning, but a repeating pattern of expansion and contraction. In Paul Steinhardt’s corners of the ...

The conventional method for analyzing 24-h ambulatory blood pressure monitoring (24-h ABPM) is insufficient to deal with the large amount of data collected. The aim of this study was to develop a ...

BUFFALO, N.Y. — In trying to understand the nature of the cosmos, some theorists propose that the universe expands and contracts in endless cycles. Because this behavior is hypothesized to be ...

A new cosmological model demonstrates the universe can endlessly expand and contract, providing a rival to Big Bang theories and solving a thorny modern physics problem, according to University of ...

Two theoretical physicists have developed a model that could explain why the cosmological constant takes the small, positive value that it does in today's universe. The value of the constant is ...

The universe undergoes an endless series of big bangs and cosmic crunches separated by periods of expansion and contraction, according to the latest cosmological theory. Paul Steinhardt of Princeton ...

In Paul Steinhardt’s corners of the cosmology world, to say that history repeats itself would be a laughable understatement. That’s because according to him and a handful of peers, the universe’s form ...

A new study by physicists highlights one way that cyclic or 'bouncing' cosmologies fall flat. 'People proposed bouncing universes to make the universe infinite into the past, but what we show is that ...

A cyclic universe, which bounces through a series of big bangs and “big crunches”, could solve the puzzle of our cosmological constant, physicists suggest. The cosmological constant represents the ...
