We saw the movie Interstellar last night.

We thought it was a great movie, but I had forgotten how much effort has been put into having real science in the movie.

NBC News has an article,  After ‘Cosmos,’ Neil deGrasse Tyson Dives Into Science of ‘Interstellar’, that goes into Neil DeGrasse Tyson’s comments about the movie.  There are numerous web links in the article that I am still following.

Here is a little featurette that I found from following the links. Supposedly not full of spoilers. INTERSTELLAR Featurette – The Science Of Interstellar (2014) Matthew McConaughey Sci-Fi Movie HD.

I’ll let you follow your own trail through the links whenever you are ready. Some of them have spoilers in them, so you might want to see the movie first. Just remember that the science is pretty real given that this is a movie and by necessity it has to go beyond what we already know.

Here is a question that perhaps someone out there can answer. What role did Topher Grace play in the movie? We think we have figured it out, but we cannot find anything on the web that definitely confirms what we think. We can find the name of the character he plays, but that does not help us be certain of who that character was. If you have the answer, leave a link to the answer rather than an explanation. we don’t want any spoilers for the people who have not seen the movie yet.

Lot’s of spoilers in the following link

This article does not answer the question about Topher Grace, but it does explain some things we weren’t sure about. The table of contents links to other pages seem to be broken, but if you read the first page to the end, you will be able to navigate to succeeding pages.
