2021年5月20日 · According to the best of current physical theories, space-time explains the unusual relativistic effects that arise from traveling near the speed of light as well as the …

2025年1月29日 · space-time, in physical science, single concept that recognizes the union of space and time, first proposed by the mathematician Hermann Minkowski in 1908 as a way to …

Spacetime or space–time is a mathematical model that joins space and time into a single idea called a continuum. This four-dimensional continuum is known as Minkowski space. …

2022年2月1日 · Spacetime may emerge from a more fundamental reality. Figuring out how could unlock the most urgent goal in physics—a quantum theory of gravity

2018年6月1日 · Physicists believe that at the tiniest scales, space emerges from quanta. What might these building blocks look like? People have always taken space for granted. It is just …

Gravity feels strongest where spacetime is most curved, and it vanishes where spacetime is flat. This is the core of Einstein's theory of general relativity, which is often summed up in words as …

2024年1月24日 · Ever heard of spacetime? For many of us, learning about this seemingly strange concept muddles what we knew about the physics of space, which we thought were relatively …
