The universe could be infinite in extent or it could be finite; but the evidence that leads to the inflationary model of the early universe also implies that the "total universe" is much larger than the observable universe. Thus any edges or exotic geometries or topologies would not be directly observable, since light has not reached scales on ...
In the case of accelerated expansion, ¨ is positive; therefore, ˙ was smaller in the past than today. Thus, an accelerating universe took a longer time to expand from 2/3 to 1 times its present size, compared to a non-accelerating universe with constant ˙ and the same present-day value of the Hubble constant. This results in a larger light ...
Two years of data from NASA's James Webb Space Telescope have now validated the Hubble Space Telescope's earlier finding that the rate of the universe's expansion is faster - by about 8% - than ...
In a big bang with only the matter and radiation known in the Standard Model, two widely separated regions of the observable universe cannot have equilibrated because they move apart from each other faster than the speed of light and thus have never come into causal contact. In the early Universe, it was not possible to send a light signal ...
It appears to be expanding faster today than it did in the past There is something unexpected happening in the universe, Nasa’s most powerful ever telescope shows Skip to main content
New measurements from the Hubble telescope suggest the universe is expanding between five and nine percent faster than scientists initially thought. NASA and the ESA measured the distance to stars ...
Faster-than-light (superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light in vacuum (c). The special theory of relativity implies that only particles with zero rest mass (i.e., photons ) may travel at the speed of light, and that nothing may travel faster.
The universe is expanding faster than previously believed, a surprising discovery that could test part of Albert Einstein's theory of relativity. Astronomers say universe expanding faster than ...
