A diagram-type image representing stellar shells and tidal ... and hence the distance to them in an expanding universe, in an observed volume of space. With such galactic distance measurements, it's ...

The Vera C. Rubin Observatory is set to revolutionize our understanding of the cosmos by detecting millions of exploding ...

Nobel laureate Dr. James Peebles will discuss the still-unanswered questions regarding the expansion of the universe, dark matter and more. We have good evidence that the universe we see around us is ...

The expansion of the Universe is not constant ... Our Sun is on one of the spiral arms as shown in the diagram: The Sun's orbital speed is determined almost entirely by the gravitational pull ...

A new study published in Scientific Reports simulates particle creation in an expanding universe using IBM quantum computers, ...

Figure caption, Lower diagram shows spectrum of light redshifted from a distant galaxy moving away from the Earth The upper diagram shows the absorption spectrum from a stationary galaxy with one ...

Here’s how it works. The Hubble tension just got tenser — with new measurements revealing that the universe is expanding faster than our current understanding of physics can explain.

The Universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous -- and highly debated -- results had shown: The Universe is expanding faster than predicted ...

Researchers have successfully simulated particle creation in an expanding universe using IBM's advanced quantum computers.

The universe appears to be expanding at a staggering speed, much faster than expected. A recent study reinforces this observation, confirming an expansion that contradicts current ...
