Welcome to Phys/TempE 404: Causal Time Travel Backwards! This is a highly required course in Physics syllabus here at Miskatonic State Institute of Technology. Many of you also take this course as an advanced elective in temporal engineering degree programs – welcome to the Physics Department (and give up all hope!). My office is on the second floor of the Science and Time Studies Hall. When my door is open, feel free to stop at any issue—course-related, science-related, or about why there are portals built into every staircase that leads to the second floor that throws you to the first. Seriously in office hours: AMA – Ask me anything – but only during working hours and only in my office, Please and thank you in advance!

In this course we will explore the basics of ordinary space-time travel in both the “past” and “future” cones of light. In an elementary course, I explored the causal structure of ordinary spacetime. Niven’s theory is the basis for the conclusion you should have drawn from this course of study, namely: “Any world in which arbitrary time travel is possible will automatically destroy any state under which this mechanism is discovered or used.”

We will explore practical violations of Niven’s theory. For smart, you’ll be glad to know More than half of the students who attempt to take this course will achieve a passing score! In the end! At some point, either in the distant future, or in the distant past, and for some of you, now!

Since the final project involves building a working time machine using what you have learned in this course and materials in the University Project Lab, it will be necessary for you to sign the accompanying Waiver of Liability to reimburse the Institute (and your humble professor) in case you work in error (or on purpose) It erases your existence, the existence of the institute, or perhaps the universe itself.

The textbook we’ll be using this semester will be published a little over 100 years from now: The shadow out of time: principles of time-like closed orbitals in spacetime (2nd ed.) by a giant in our field, 1963 Nobel laureate and former member of our department, Professor Howard Lovecraft. The library had several copies of this book two years ago, but if you can get hold of the fourth edition, you can definitely use that. Many of the problems in Chapter 5 will be numbered differently in Edition 4 than in Edition 2, so you’ll need to consult your classmates if you have a later edition of the book. The third and first versions are not available.see Niven’s Law), so anyone who intends to use these will get an additional 10% score on each problem set you assigned in the last semester.

We have a total of eight problem sets in this course, each of which is due today at 4pm to the drop box in our Campus Learning Management System, blackboard hole. I know, by now you are familiar with the unreasonable demands that our faculty members place on MSIT students. We ask you to “sip water from the fire hose” on a regular basis, but I’m sure you’ll be able to get the bulk of the work done and deliver by the deadline. As our school motto says: I don’t understand, I’m not a citizenor, “If you can’t figure it out for yourself, you don’t belong here,” which is relayed to the vulgar students in Randolph Carter Hall’s ornate basements, leading to “Only Life Can Kill You” and “IHTFP.”

The final exam took place last month, and you uploaded your final score to blackboard hole Where you will be able to check it. Some of you may have guiding questions, such as “How did I fail a course I haven’t taken yet?” This is of course a perfectly normal question.

If you have any (other) questions about your score, or about how the points are allocated, please feel free to contact me via email. I receive thousands of emails every day, from the distant future as well as the past: everything from 18th century nut tins asking me to look at their world-shaking manuscripts, Mathematical principles, of the disguised and undisguised threats from immeasurably powerful cosmic beings that mean great harm to us – or I would if I had not immediately participated in its latest investment opportunity. One of these beings, the Secretary of the Institute, will certainly be in touch with each of you. Answer these Email messages. Excuse me.

The midterm project involves a very simple task of sending a letter to your great-grandparents instructing them to open an interest-bearing account with the institute. Earning a passing degree on a mid-term project will almost certainly fund your entire education at MSIT.

My policy for late or missed assignments is Complete the final project. Late assignments for credit will not be accepted. The only exception to this policy is for the final project. Successful completion of your time machine will earn you an arbitrarily long extension. But I doubt you’ll need it in this case.

Anyone wishing to leave the course, as part of a mid-semester project, can send themselves the appropriate letter two weeks in advance.

I hope you enjoyed this semester, I have been looking forward to it and looking forward to it for a long time.

The story behind the story

Galen T Beckett reveals the inspiration behind it Physics/Time Geometry 404: Backward Causal Time Travel.

While in the spring thoughts of youth may turn slightly to thoughts of love, in late summer my thoughts always turn to thoughts of “Honey, where has all the time gone…I have to prepare my syllabus!” The end point of the panicked realization that I am (again) out of time is a daydream of a syllabus you see here.
