    bolide reacted to Gerold's post in the thread How the 'Great Filter' could explain why we haven't found intelligent aliens with Like.

    The idea of this species, which has barely had language for a couple hundred thousand years, living in this not-so-very-stable universe...

    Agree with everything you said except "The cost of orbiting mass is now trivial," at least as applied to the ISS. Nothing trivial about...

    Regarding the "newness" of Earth compared to the galaxy: What the conditions have been in our galaxy since it was formed is not yet...

    bolide replied to the thread Scientists await signal from NASA's Parker Solar Probe after historic close sun flyby. Will it phone home?.

    Looks like a tradeoff between how much fuel you can carry and how long you want the astronauts to be traveling.

    I'll stand corrected. So 5½ hours @ 1g up to speed, and another 5½ @ 1g to stop. But what about the energy requirements for accelerating...

    No, the limit is the endurance of the human body in the conditions produced by the trip. How do you get to 400,000 mph?

    bolide reacted to Joexo's post in the thread How the 'Great Filter' could explain why we haven't found intelligent aliens with Like.

    Couldn't also be the case that civilizations are so incredibly rare that maybe one or two happen per galaxy? I don't see why we should...

    The ISS is not an "interstellar ship." It's not even capable of leaving Earth orbit. Our telescopes are barely "interstellar," never...

    I expect that setting down the ISS on the moon would exceed the cost of sending astronauts to the moon.

    bolide reacted to MHF's post in the thread Scientists find highest energy cosmic ray electrons ever seen with Like.

    I was not aware of any stars (burning or dark) 2 lightyears from the solar system. Proxima Centauri is double that distance.

    bolide replied to the thread If dark matter is 'invisible,' how do we know it exists?.

    My point was that you seemed to be defending the idea that something like the "aether" might independently exist, as a medium for...

    bolide replied to the thread If dark matter is 'invisible,' how do we know it exists?.

    What is a "field," in this usage? Is it supposed (or do you suppose) that it is something that exists independently of anything that may...
