Marm

For some reason I was doing my special relativity exam that I did in school a week ago. The question I was working on was about how much the astronauts inside a rocket bounded for Alpha Centauri from Earth at v=0.95c aged during the journey.
I remember doing some calculations on the paper in front of me. I used a blue pen but the ink came out in all sorts of colours.


After I woke up I reflected upon that dream and I was actually pretty amazed. I was able to read quite a large chunk of text in my dream without the words going fuzzy, had some precise figures (ie. velocity=0.95c), and did some time dilation calculations that actually made some sense.
Of course I didn't expect to work out the answer to that question because once I woke up I realised that it was actually incomplete. In the actual exam, I was told that the distance from Earth to Alpha Centauri is 4.3 light years. Without this information I couldn't have worked it out.
On the whole it was a great and memorable dream!
