The observed near flatness of galactic rotation curves has long been interpreted as evidence for large amounts of non-baryonic dark matter. Here we show that this phenom ...

Since decades quantum gravity tries to close the gap to general relativity, but all attempts remain pure theory without empirical test. The present study now extends loop quantum gravity to a verified ...

For nine months in 2022, moss lived in space. It wasn’t in a lab aboard the International Space Station, like other gardening experiments conducted in orbit — rather, the moss was attached to the ...

There has been much discussion in the space community recently about building large data centers in orbit to avoid the environmental consequences of sprawling computing facilities on Earth. These ...

ABSTRACT: First of all, we will reiterate a mechanism for relic early universe gravitons. This is the precursor of the main result of this paper and involves the decay of micro black holes, with relic ...
