Chrono, a bunch of questions (topics in bold)...
Politics
1 - What is the capital of the US in 500 years? Is it still Washington DC?
2 - Why and when did New York become the capital of the world?
3 - I'm from Baltimore, Maryland (USA - NE of Washington DC. Will Baltimore and Washington merge into 1 super-city as their suburbs grow? (What will Baltimore be like then?)
4 - Just a curiosity, is my city involved in any historical events in the next 500 years?
Sports
5 - What sports will still be around? (Baseball, American Football, soccer, basketball, etc.)
6 - Will Baltimore, Maryland ever host the Olympics?
7 - What new sports will there be?
8 - Where will the next, say, 10 olympics be held after Athens?

10 - Is the food diet of people any different?
11 - Is the Internet as we know it still around?
12 - What types of personal technology will people have?
13 - How do hospitals of the future function (and the technology they have)?
Science & Discoveries
14 - What would you say are the most notable scientific, and natural discoveries are in the 21st century?
15 - You mentioned other lifeforms, when do people meet these lifeforms, and how is first contact made? What was the general reaction amongst the population each time?
16 - Why do the Scarrans hate you?
17 - Can you give a general list of the lifeforms and their lifestyles? (including primitive ones)
18 - How is Venus and Mars being terraformed, and how far along is that progress? (Does Mars have liquid water now? Is it being warmed up for for water? Does it have plants?)
19 - How does mandkind have enough water for the Earth, Moon, Mars and Venus?
20 - When (year) do we discover life on Jupiter's moons?
21 - You mentioned there's 3 species that have space travel. I've seen 2 (Scarrans and Lizarans). What's the other one, and can you discribe them?
22 - Can you discribe the culture (daily life) of the other lifeforms? What is their home planet like? Do they breathe the same type of air, or is their athmosphere a different mix of gases other than oxygen and nitrogen)?
Other questions
23 - It seems you've seen Star Trek. What parts would you say are 'accurate' (i.e., science fiction becoming science fact)?
24 - Are their still computer games in 500 years? Or, is everything done with the life simulator?
25 - Will there be any natural or manmade disaters in the US?
26 - What type of technology do the other lifeforms have?
27 - Why is it that the Lizarans already speak a form of English? I do find that hard to swallow a bit... after all, they would have a culture completely different than ours.
28 - Will anything happen to Yellowstone National Park (it has an active culdera beneath the park).
29 - Do any countries/region ever unite and form a larger country? (like Europe seems to be doing).
30 - Can you tell us more about WWIII, like what happens, and why it starts?
31 - What was the reason for the Scarran war?
32 - There's currently a theory that time travel might be possible (along with String Theory), however, the catch is that while you can go forward in time, you can't go back in time before the first time travel device was made. There was a program on this recently, have you seen it? Why is it that your time travel seems to be the opposite of what the current theory is?
33 - How right or wrong was Einstein?
34 - You say there's over 60 billion people on Earth. Why doesn't the world population stagnate at 10 billion like is theorized? Or, is that the population for Earth, the Moon, Mars and Venus?
35 - Can you tell us more about the Moon, Mars and Venus? How is the terraforming done, and what's life like on those planets?
36 - Will animals like tigers, elephants, rhinos, etc. become extinct, or still be around?
37 - What's the education system like?
38 - Do people keep any other pets, or new species of animals for pets? (Do people still keep cats, dogs, birds, etc.? Any new breeds of cats/birds/dogs)
39 - What's it like to grow up in 2500ad?
40 - Will the "Big One" (massive earthquake) strike California? (if so, what year, if you can tell)
