What would you ask an astronomer?

#1

Post by Buckethead 2.0 »

Vanessa (Butterfly Maiden for those who do not know her yet) encouraged me to pose that question, in case anyone here at TSS might like to ask Chris Impey an astronomy question, to which I would ask him. And if I got a response, I would surely post it here.

Or you could watch the chat and ask him yourself. You would need the proper email address, or a You Tube account, so a heads up there.

Chris has a weekly live You Tube chat, and he answered my question and I didn't feel like he had any bit of arrogance, or anything like that. Someone asked him what space smells like. I was like :shock: :lol: He took the question seriously and respectfully.

You guys and girls here are brilliant, and I would love to hear if you have any questions. It would be fun I think.

I plan to watch him every time for the next few weeks, because I do learn things, as well as solidify what I already know.

Is anyone interested in asking Chris a question? I think he does a fine job explaining things to the audience imo.

Okay Eric, I'll start one off, but I don't know whether this would fall within his expertise though.

"If we found another habitable planet, that could be so far away it would take years to reach it, would some form of cryogenics be feasible to keep the bodies in stasis until arrival?"

Probably a bit far-fetched at the moment Eric, but just curious.

Thanks Vanessa! I will certainly forward all questions by everyone who joins in. And I have watched him twice now, and he gets questions ranging from quasars, neutron stars, stars that might wipe us out (he very succinctly felt we are not in imminent danger, because any "nearby" candidates are not anywhere near the end of their life in the cosmos) nebulae, planets, the Moon, and questions like yours.

I am going to create a text file, so all I have to do is copy and paste. Then I will respond here with answers and time stamp so you can go right to it in the video if not watching the chat from the beginning.

About astronauts, the kitchen sink really. And he never rolls his eyes, or even jokes too much.

So no question is off limits from what I have seen.

That doesn't seem far-fetched to me actually. But hey, what do I know? :lol:

Everyone, a little heads up is warranted...there are a lot of questions in each chat, so I will keep posting your questions, and if I don't get a response, I will try until I do. He usually averages about 30 or so in the one hour that it runs. I will try again the following week if he doesn't get to your question.

Mine is going to be, "among the many innovative technologies aboard the James-Webb Space Telescope, which will be the most groundbreaking in our understanding of the furthest reaches of the universe?"

And "do you like Oreos?" :lol: just kidding !

Kind of sounds like some questions were to be ignored if raised. Maybe he does not want to address it for some reason.

Einstein-Cartan gravity is highly specialized and mathematically difficult. It is out of fashion in the US and only pursued by folks in central and eastern Europe.

Ah! He is a western European (British). Fritz, regarding pakarinen's phrase that you quoted, is the Einstein-Cartan gravity thing related in any way with cyclic ekpyrotic cosmology ?

Cyclic ekpyriotic cosmology and Einstein Cartan cosmology are similar only in the cyclic aspect. Both have no Big Bang but rather a series of Big Bounces. So both have no need for inflation or an inflaton particle.

Apart from that superficial similarity they are fundamentally different conceptually,

Cyclic ekpyriotic cosmology is based on ideas from string theory and M theory and thus needs supersymmetry (SUSY) to be valid. The absence of SUSY particles at the LHC is an embarrassment for its fans.

Einstein Cartan is compatible with all previous experiments in General Relativity and can work with the Standard Model of particle physics as well as string theory.
