A mock debate on time with British physicist and science writer Julian Barbour and NYU philosophy professor Tim Maudlin, reposted from FQXi’s Setting Time Aright conference in Copenhagen.
People have dreamed of colonizing the Red Planet for more than a century. USA Today takes a look at NASA’s most recent Mars plan for landing astronauts there about 2035. The first outposts could come after 2060. “Mars has captured the human imagination certainly since people started gazing up at the sky,” says NASA science…
What is biological immortality? To be fair, it’s not the promise of a paradisiacal garden. Neither is it the ultimate, or final, defeat of death. Instead, biological immortality has to do with aging. An organism that is biologically immortal does not age. We primarily age (the theory goes) because the cells that comprise us age….
If we want to find intelligent life elsewhere in the universe, it might be wise to look for stars with asteroid belts similar the one in our own Solar System. According to the theory of punctuated equilibrium, evolution goes faster and further when life has to make rapid changes to survive new environments — and…
It was a provocative finding: strange bacteria in a California lake that thrived on something completely unexpected — arsenic. What it suggested is that life, a very different kind of life, could possibly exist on some other planet. The research, published by a leading scientific journal in 2010, led to overheated speculation about how life…
“Shocking” find may redraw picture of solar system’s cosmic shield.
The early universe was a vastly different place from the one we see today. No stars burned in faraway galaxies — there weren’t any galaxies. Instead, photons were trapped in a dance with the hot plasma of protons and electrons that suffused the universe. Sound waves rang out across this primordial soup, sloshing gas and…
