Quantum Apostrophe: So you're learning that none of the delusional space nutter fantasies are possible, right? All it takes is high-school physics, after all.


Sending astronauts to Mars is quite possible, if not cost effective at the moment. That's what this thread is about, right? Going to Mars?

Quantum Apostrophe: thinks atoms have an age


Err... am I missing something here? I'm pretty sure most hydrogen atoms are 13.7 billion years old. The average age of a sample of uranium atoms can be calculated by look at their radioactive decay. Unless you meant something else by "age."

rocky_howard: Seriously, what kind of reaction is that? Nobody cares about the personal value the quote has for you.


I could have gone with the simpler "I disagree, I think it's a great quote," but that somehow seems less interesting.

Lanadapter: Fly me to the moon and let me play among the stars, let me see what spring is like on jupiter and mars.

See what you did there.

Frank Sinatra, Bart Howard, Felicia Sanders, Kaye Ballard and two dozen other artists hope you're trolling.

silly season: The Bad Astronomer: badLogic: Man, that Phil Plait guy is a real kill joy. He must be blast at parties.
Next thing you know he will be telling us that Galaxy Quest is not real.
You mean they are not ALL "historical documents." Surely, you don't think Gilligan's Island is a...

I'm an excellent dancer.

Do you bring your own stripper pole?


Pics, or it didn't happen!

Exactly. So how can a person be 25, or the Earth 4 billion? The point is you can't tell one atom of an element from the other, they behave the same, they are the same. Therefore there's no real, physical limit to biological age, the limits has got to be somewhere else. It's programmed, it's a pattern. That's what "age" is, a pattern of certain atoms. The atoms themselves don't have an age. You can't tell one hydrogen atom from another. There's no stockpile of worn out hydrogen atoms on Earth, atoms "tired" of being hydrogen. Any hydrogen will be the same and react the same whether it's from the Big Bang or a proton freshly spat out some nuclear reaction.

The fact that we burn oil made of "65 million year old" molecules surely proves that.

So life extension is possible. For every human on this planet. We in the West have already extended our youth and our lifespan without even knowing about DNA, we did most of that in the early 20th century.

OTOH, F still equals ma, and there are no new energy sources, no new propulsion technologies or even theories to get around F=ma. Therefore, except for some stunts, manned space travel will never be more than that, a stunt for a handful of very rich people, or very dedicated test pilots.

There will never be colonies on the Moon, or Mars condos, or asteroid mining, or space-based solar arrays.

Period. And no wiggling about definitions. Yes, Luna 16 brought back moon rocks in a fully automated system in the early '70s. That's not economically sustainable mining.

It is however a shame that Luna 16 seems to be forgotten. The Russians did so much with so little.

And don't forget, if you drive your car faster than 30mph with the top down you won't be able to breathe either.

Not trolling, just making a ref to a very well-known use of the song. Relax.

Magorn: meat0918: At least this one is real. Right?

I'm kinda ok with people being forced from their comfort zones and having to deal with the fact that we live on a "pale blue dot".


Ask ten different scientists about the environment, population control, genetics and you'll get ten different answers, but there's one thing every scientist on the planet agrees on. Whether it happens in a hundred years or a thousand years or a million years, eventually our Sun will grow cold and go out. When that happens, it won't just take us. It'll take Marilyn Monroe and Lao-Tzu and Einstein and Morobuto and Buddy Holly and Aristophenes .. and all of this .. all of this was for nothing unless we go to the stars.


Yeah, but eventually all of the other stars will have died as well. Then it will be as if none of us ever existed.
