At the quantum level, space and time resemble a foam of microscopic bubbles. Neural networks have learned to instantly compute their interactions, replacing hours of calculations. This brings us closer to understanding the structure of the Universe at the smallest scales.

Engineers are leaning on computers more to design minuscule light circuits, but the output can be a whimsical mosaic. Now, scientists have a tool that shines a light on the weakest links, preventing expensive production flops.

Computer modeling has shown that the Moon's uneven terrain and crust thickness turn its surface into an amplifier of spacetime ripples. In the region of the South Pole–Aitken basin, the signal is amplified dozens of times, paving the way for future lunar observatories capable of detecting the merger

Algorithms sift through millions of options, suggesting new ideas to scientists—from medicines to distant planets. Robotic labs then test these hypotheses immediately, making science faster and more accessible.

Calculating molecules is a complex task requiring lengthy setup. The new method uses ready-made 'distance rules' for electrons from simple atoms, much like tailoring a dress from ready-made patterns. This not only saves time but also unexpectedly improves energy accuracy.

Graphs are diagrams made of dots and lines. Determining whether two graphs have the same structure, even if drawn differently, is often difficult. Scientists have found a way by envisioning a graph as a landscape of hills and valleys. Each node gets its own curvature measure. By comparing these curv

Scientists built a toolkit that checks warp drives for any observer, even at warp speeds. It ranks them by how much they violate nature's energy laws. The Rodal design is the calmest, Alcubierre's the wildest. This steers research toward more realistic warp concepts.

At the crucial moment of the reaction, when hydrogen ions overcome the barrier, chaos freezes, enhancing tunneling. Scientists have calculated which vibrations bring chaos back and slow down the process — this will allow more accurate modeling of distant planets' atmospheres.

Scientists tested hundreds of warp-shell configurations that compress and stretch space. At the boundary between shell and void, the laws of ordinary physics were always violated. Even a static warp bubble is impossible without exotic matter.
