Mathematics is like nothing else. The truths of math seem to be unrelated to anything else—independent of human beings, independent of the universe. The sum of 2 + 3 = 5 cannot not be true; this means that 3 + 2 = 5 would be true even if there were never any human beings, even if there were never a universe! When then, deeply, is mathematics?

Universe decays faster than thought, but still takes a long time

The universe is decaying much faster than thought. This is shown by calculations of three scientists at Radboud University on the so-called Hawking radiation. They calculate that the last stellar remnants take about 1078 years (a 1 with 78 zeros) to perish. That is much shorter than the previously postulated 101100 years (a 1 with 1100 zeros).

We Now Know What Switched The Lights on at The Dawn of Time

We finally know what brought light to the dark and formless void of the early Universe.

According to data from the Hubble and James Webb Space Telescopes, the origins of the free-flying photons in the early cosmic dawn were small dwarf galaxies that flared to life, clearing the fog of murky hydrogen that filled intergalactic space. A paper about the research was published in February 2024.

“This discovery unveils the crucial role played by ultra-faint galaxies in the early Universe’s evolution,” said astrophysicist Iryna Chemerynska of the Institut d’Astrophysique de Paris.

US startup unveils prototype of excavator to mine helium-3 from moon

Interestingly, however, despite Komatsu’s early lead, Vermeer and Interlune seem to have caught up and could be ahead. For example, the new prototype is bigger and full-scale, showing great promise through testing.

The Vermeer-Interlune excavator has a larger excavation capacity, more funding and government support. To this end, Interlune is targeting a lunar mission by 2030.

“The high-rate excavation needed to harvest helium-3 from the moon in large quantities has never been attempted before, let alone with high efficiency,” said Gary Lai, Interlune co-founder and CTO.

Water ice detected in a debris disk around young nearby star

Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have detected water ice in a debris disk around HD 181327—a young star located within 160 light years away from the Earth. The finding was reported in a paper published May 14 in the journal Nature.

Debris disks are collections of small bodies around stars, including asteroids, Kuiper belt objects, comets, and also micron-sized debris dust. Observations of debris disks could help us better understand the evolution of planetary systems, the composition of dust, comets, and planetesimals outside our solar system.

Given that water plays a key role in the formation of planets and minor bodies, astronomers look for its presence also in debris disks. However, although water ice has been commonly detected in Kuiper belt objects and comets in the solar system, no definitive evidence for water ice in extrasolar debris disks has been found to date.

Scientist shows it is physically impossible for us to be living in a simulation

The trumpets have sounded, the simulation hypothesis, the idea that we are all living in a simulation of our universe created by our distant descendants living in the “real” universe, is dead.

In a new paper, Italian physicist Franco Vazza, a researcher in astrophysics simulations, claims that it is impossible to simulate even a sizeable portion of the universe within itself.

This conclusion seems intuitively obvious. While the universe may be bigger on the inside, it doesn’t seem like you should be able to represent the whole thing inside itself.
