Examples would be good

It seems apparent to me that if time travel is possible at all, it already exists in the future and that our own time period is subject to incursions from time travelers. I think this kind of travel could even be a form of tourism for visitors from the future. What do you think?

You always see movies and cartoons where people ride on them and they help people escape from the t-rex, but were they really that friendly. Hippo are portrayed as friendlies but will kill you in a heartbeat. They wont eat you but they will kill you. Is that the way brontasaurus's were or would they really give rides to kids and help them escape the evil t-rex.

Obviously, if it were to happen, it would not happen in our lifetimes probably. I just can't see the money and research that it would take ever actually going into it. We just have too many problems here on Earth to devote our time, manpower, and resources on a project of that magnitude. What do you think?

I would like to simulate FEA of spherical dome when subjected to wind and snow loading in NASTRAN but do not know how to do it. Can anybody help me? I used to use axisymmetric element in NASTRAN to do internal pressure and self weight analysis but I dont know how to model the dome using axisymmetric element when it is subjected to wind and snow loading. I have no idea which type of load should be chosen in doing this analysis. Thanks in advance.
