Trace breaks down some of his favorite theories for what the universe is. Are we really just living in a computer simulation?
The likelihood that a South Pole-based telescope detected elusive gravitational waves earlier this year has just taken another nosedive. Continue reading â†’
Chemical signature of ancient star suggests it incorporated material blasted into space by a supernova explosion from huge star in early universe.
An extraordinary amount of ultraviolet light appears to be missing from the universe, scientists have found.
The idea that there are an infinite number of universes beyond our own is assumed impossible to prove or disprove -- but a new computer model might give us hints as to what evidence to look for. Continue reading â†’
The recent discovery of gravitational waves present in cosmic microwave background radiation -- posited as evidence of the big bang -- has been called into question by, of all things, dust that needs to be accounted for.
Scientists studying more than 140,000 extremely bright galaxies have calculated the expansion of the universe with unprecedented accuracy.
