Accelerating astrophysics with the SpaceX Starship

By substantially increasing the mass and volume of its reusable transportation system without raising costs, SpaceX may enable NASA to implement future missions years ahead of schedule.

INTRO: Researchers used data from the Dark Energy Survey and the South Pole Telescope to re-calculate the total amount and distribution of matter in the universe. They found that there’s about six times as much dark matter in the universe as there is regular matter, a finding consistent with previous measurements.
But the team also found that the matter was less clumped together than previously thought, a finding detailed in a set of three papers, all published this week in Physical Review D... (MORE - details)
3 new studies indicate a conflict at the heart of cosmology
https://bigthink.com/hard-science/conflict-cosmology/
KEY POINTS: Telescopes are essentially time machines. As we examine galaxies that are at greater and greater distances from the Earth, we are looking further and further back in time. A new series of studies that examine the "clumpiness" of the Universe indicates that there might be a conflict at the heart of cosmology. The Big Bang theory is still sound, but it may need to be tweaked... (MORE - details)
