Space - Science News Space The biggest black hole smashup ever detected challenges physics theories Gravitational waves spotted by LIGO reveal two black holes, 140 and 100 times the mass of the sun, merged to become a
Space missions spanned the solar system in 2024 - Science News From monitoring Mercury to launching a new adventure to an icy moon of Jupiter, spacecraft and astronauts made great strides in 2024 Here are some of the highlights of this year in space The
As Expansion continues, Time speeds up, True or False? In our evolving universe, space is expanding (due to dark energy?), causing regions with lower mass density to experience faster time progression than dense areas My question suggests that the universe, as a whole, is expanding (without additional mass added) and lowering mass density and therefore the 'proper time ' (Cosmic Time) is speeding up

Argument by analogy | Space. com Forums Yes, GR does describe "the gravitational interaction with matter", but this doesn't address the greater dance between space and matter As Wheeler said, "Space tells matter how to move Matter tells space how to curve " But first once has to recognize that space isn't the emptiness we thought it was "It's really somethin' that space ain't
Why so Slow? | Space. com Forums Problems with nose cone heating in interstellar space don't become noticeable until about 0 1 c where it is about 100W m^2 At 0 8c it runs into the megawatts Chemical propulsion is off the mark by a factor of 10,000 Fission propulsion can get us up to about 0 003 c Fusion could theoretically get us to 0 007 c
The Empathic Universe | Space. com Forums Similarly, 3-dimensional space can (as a part of say a hyperspherical universe) be considered as 'something' That is 'a whole object', a thing The word empathy is perhaps not quite right but it implies a characteristic of a 'thing' that may exist just from the wholeness of something eg life or a rod
