After spending the beginning of the week in the Eastern time zone at the AAPT meeting in Greensboro, NC, I am now planning to spend the second half of my week in the Pacific time zone attending the ASP’s Cosmos in the Classroom meeting in Pomona, CA. I’m writing this from Dallas, where I am currently waiting for my flight to leave.
I learned a few key lessons today: if you tie your poster tube to your carry-on bag it counts as 1 carry on (even though you have to take them apart to fit them into the overhead bin; terminals A and C in Dallas do not have enough electrical outlets or departure boards; when you ask the nice lady behind the counter at 2:15 after landing late where your 2:55 flight is departing from, she will tell you the gate and instruct you to run, even if your flight is delayed an hour; wearing flip flops to fly is convenient while passing through security, but detrimental when trying to run between gates; I personally do not have the coordination to carry a back-pack, poster tube, roller bag and to run at the same time; falling while running on escalators with a poster tub, backpack, and rollar bag hurts; finding out your flight is delayed and their is an Au Bon Pain next to your gate can (if you are me) make all the aforementioned worth it because now there is extra time to enjoy a soy milk latte and Mediterranean veggie wrap.
I had forgotten how much I like Au Bon Pain. Mmmm… Fetta and hummus.
Pam..I like that little tram in Dallas..totally automatic.
I just got back from San diego so I understand the time shift..
So ok here goes..
I read your posting on i think earth & science..whatever it was..
It was about black holes swallowing matter..
Something bothered me..
Let’s say a super massive black hole starts pulling in massive amounts of matter..would not the gravity of the matter being pulled in suck more matter with it? Think of a sink with the drain open..
As more matter swirls in, doesn’t it pull in everything behind it?
like a sink all matter pulls into the black hole?
Now i say this TV show, that stated that the speed of all stars in a galaxy is directly tied to a black hole..right to the edge of the black hole..so isn’t all mass in the galaxy tied in some way to the gravity of the black hole?
Wierd..ok one last question.. you know when the mass of a star grows too large and it explodes? Supernova?
So let’s say a compacted galaxy swirls into a black hole..massive amounts of mass is sucked into a blackhole…
There is no super super super nova that takes places? Just streams of energy at the poles? Why does the math break down? Why not a blackhole explosion with a billion billion star masses crushed together? If the mass is so great that an outward explosion doesn’t take place..then doesn’t the math change at a certain theshold and doesn’t that affect all of the dark matter equations?
Have a great trip..
I suffered the cross-US air travel pain last week on my way to Santa Barbara to work with some collaborators for a few weeks. It is odd to think that I’ll be in the same time zone as you 😉
Back-pack for Pamela, 45 bucks…
Roller bag that does 15 miles per hour in an airport, $150…
A good pair of sneakers to keep up, priceless
As the designated “tube toter” on my trip, I can definitely say that the poster tube has the highest annoyance-per-pound rating of any piece of luggage I have encountered. I think all of the passengers on either side of the airplane aisle would agree with me. Mr. Tube and I are not friends…
