Probing Dark Energy Beyond addressing the Hubble tension, the Einstein zig-zag could also shed light on dark energy, the mysterious force driving the accelerated expansion of the universe.

Oh, but that light still travels at the speed of light, so it takes more time to reach the other mirror. And if the spaceship is moving at a speed of c/2, that would be a lot more time.

This NASA/ESA Hubble Space Telescope image offers us the chance to see a distant galaxy now some 19.5 billion light-years from Earth (but appearing as it did around 11 billion years ago, when the ...

The circle of light is created by gravitational lensing around a galaxy 500 million light years away called NGC 6505 (ESA/Euclid/Euclid Consortium/Nasa, image processing by T Li/PA) ...

The ring of light, known as an Einstein Ring, was discovered in September 2023 by Euclid, a space telescope on a six-year mission to map out the cosmos by observing billions of galaxies.

At the heart of this system, labeled J1721+8842, lies a single quasar. Its light, originating from 11 billion light-years away, is split into six separate images.
