Eh? Why would the Big Bang theory have anything to say about comets?

A greenhouse pre-positioned on Mars to greet the first humans would seem to be a must. That is, if we ever manage to land a crew there. The age of exploration (Columbus, Magellan, etc.) does not provide much of a guide to this undertaking. They merely extended the range of sailships by a few...

So if I understand correctly, the objects tossed by the cosmonauts from ISS will NOT pose a threat to ISS itself. But they could, in principle, intersect orbits of satellites or debris below? A Starlink satellite could then take evasive maneuvers, but what about a piece of debris that has no...

The Ken Fabians hate hate hate Judith Curry, much more than they hate the loony-tunes flatearthers and CO2 greenhouse effect deniers. Why? Because she is reasonable, judicious, data-driven, and fair. (And she engages with the public, including detractors and critics.) Like many of the most...

Depends on which is cheaper. Making space colonies have 1 g, or genetically engineering humans to live in microgravity (to the point we might not even consider them "human" anymore).

Pride Month isn't over yet, space.com! We want rainbow-colored LGBTQWERTY articles every day until the end of the month! There'll be plenty of time for fear-mongering climate panic articles the rest of the year! You slackers!

Maybe ... Or maybe we see a sign MEN AT WORK, scaffolding, empty beer bottles ...

Well I could have expressed distance instead in parsecs, kilometers or miles. But expressing distance in terms of the time it would take light to get across was okay. Are you certain that you have understood Einstein's Theories of Relativity, Atlan?

Maybe (if the universe beyond what is observable is not infinite, and if it is not curved so that you end up in the same spot you started). If so, perhaps we would end up at a plexiglass wall with child gods curiously staring at us :)

According to current understanding, we cannot go there, ever. Not even if we had ultra-fast spaceships moving at 99 percent of the speed of light and immortal astronauts immune to feeling boredom. The reason being that "dark energy" is pushing space apart, so that the distance to the farthest...

The "science" of the alarmists is bogus and does not add up. There is no climate emergency. https://clintel.org/world-climate-declaration/ The jig is up. Their gravy train is about to come to an end, and not a moment too soon.

Traversable wormholes? I don't think so. Like anything that allows travel faster than the speed of light (perhaps "speed of causality" would be a better term), this would run into un-resolvable paradoxes. "locally superconduct our ships through spacetime" no idea what this is supposed to mean...

Agree with Atlan in general terms. However, breakout if it comes won't look like Star Trek (there will never be "warp speed") nor, probably, like Avatar (Humans 1.0 traveling at sub light speed while frozen*). Rather, I suspect the choice will be between artificial general intelligence...

Now a spaceship accelerating or decelerating in relation to our system at a significant chunk of the speed of light -- detectable from the heat signature coming from its radiators -- that, to me, would constitute uncontrovertible proof. Or perhaps a working quantum computer with a million qubits...

Bill -- are we perhaps talking past each other? I think we agree more than we disagree.
