EG1004 Lab 1701: Faster-than-light Travel
The experimental objective of this lab is to build a model that will travel faster than the speed of light.
Traveling faster than the speed of light has been subject of science fiction for centuries. The popularity of the “Star Trek�? series, originally broadcast almost 40 years ago and still in syndication, plus a number of “spin-off�? series, is proof of this.
Many people assumed that this was fantasy since Einstein’s general theory of relativity predicted that objects that approach the speed of light become increasing heavy, making it impossible to attain light speed, much less exceed it. However, it was also known that some objects such as neutrinos, always traveled greater than the speed of light. However, experiments seemed to show that neutrinos were not able to travel less than the speed of light without being destroyed, giving further evidence that somehow the speed of light could not be crossed from either direction.
Fortunately, two technologies combined to solve this problem. First, it was necessary to safely and quickly accelerate to extremely high velocities by generating and directing massive amounts of energy quickly. This was attained by using the now-familiar matter/antimatter containment vessel. Second, the space warp was discovered to be a natural phenomenon. This effect was first noted in extremely close proximity to black holes, making the phenomenon difficult to observe from Earth, and without the technology needed to reach black holes, there was no way to study them from nearby. The breakthrough came when Prof. Zefram Cochrane of Polytechnic University successfully created a small black hole in his laboratory. It should be noted that this success came after several failures where several Metrotech buildings were apparently “sucked�? into nothingness, never to be seen again, forcing him to move to an abandoned Air Force missile base in remote North Dakota.
Now, what has become trans-warp travel has become commonplace. However, this is usually accomplished with large spacecraft with crews of over 1000 people. In this lab we will “scale down�? the technology so that we can construct a small model ship that will travel faster than light for a very short time.
The model will be much simpler than a real spacecraft. Also, in order for the lab to be done in the allotted time, most of the model will already be constructed for you, including a positronic guidance system that will allow the craft to only fly in a straight line. All you will need to do is attach four stabilizers (fins) to the fuselage, insert a cartridge containing liquid hydrogen (matter) and pour in antimatter into its onboard containment, mount the craft on a stand for launch, and activate the remote launch switch.
The craft will fly straight down Jay Street to the East River. It is extremely important that the model craft be launched properly since the craft will have to fly through the supports of the Manhattan Bridge approach. At the East River the craft will hit a barrier, causing it to lose substantial velocity, and drop to sublight speed, where air friction will almost destroy it. After penetrating the barrier, the remains of the craft will travel a short distance further, and fall into the East River.
In order to verify that the craft did indeed exceed the speed of light, a strobe light will flash when the craft launches. At the barrier, two atomic clocks will run. They will indicate whether the flash of the strobe light or the craft arrived first, and the difference in time. Because the difference in time will be small, it will not be possible to accurately determine the speed of the craft, but the clocks should clearly show that the craft arrived before the light from the strobe light, showing that the craft was traveling fast then the speed of light.

Individual Lab Report
Follow the lab report guidelines laid out in the page called Specifications for Writing Your Lab Reports in the Technical Communication section of this manual. As you write, the following discussion points should be addressed in the appropriate section of your lab report:
- Describe the problem you are solving in your introduction.
- Describe, in general terms, how faster-than-light travel is possible
- Describe some applications of faster-than-light travel
- Describe how the matter/antimatter reaction occurs and its products (Note: you will have to do some online research to answer this. Be sure to put your findings in your own words to avoid plagiarism issues)
- Did your model work? What happened? If it didn’t, why didn’t it?
Team PowerPoint Presentation
Follow the presentation guidelines laid out in the page called EG1004 Lab Presentation Format in the Introduction to Technical Presentations section of this manual. When you are preparing your presentation, consider the following points:
What are some of the more widely used applications of faster-than-light travel today?
If you can look into the future, what do you think the future of space travel will be?
4 MATERIALS AND EQUIPMENT
- Spacecraft model
- Tube of Super Glue®
- Matter cartridge
- Antimatter in a containment vessel
Remember: You are required to take notes. Experimental details are easily forgotten unless written down. EG Standard Note Paper can be downloaded and printed from the [EG website|http://eg.poly.edu/Note_Paper.zip]. Use your lab notes to write the Procedure section of your lab report. At the end of each lab your TA will scan your lab notes and upload them to the EG1004 course section on MyPoly. You must attach your lab notes at the end of your lab report (use the "Insert Object" command in MS Word after your Conclusion). Keeping careful notes is an essential component of all scientific practice.
- Obtain your spacecraft model from your Lab TA. The model, without fuel, will weigh 1KG. You will have to sign a receipt acknowledging that you received the craft. All members of your team will have to sign the receipt.
- Attach the control four control surfaces (fins)
- Turn on the positronic control system using the red power switch. Have it do a Level 1 Diagnostic by pressing the yellow button next to the power switch. If a green light comes on, the control system is working. In your lab notes, note the time at which the control system was turned on since it has a limited battery life. Have your TA sign your lab notes, noting that the control system is functioning properly
- Go out the front door of the building to the curb of Jay Street. You will see the “Roaming Lab TA�? there. This TA will give you the matter cartridge containing 1KG of matter. Snap it into the model. Next, the TA will give you the antimatter containment vessel.
- CAREFULLY pour some antimatter into your model. The containment vessel will automatically pour out the proper dose of 1KG of antimatter (note: the amount of antimatter must be exactly equal to the amount of matter for this reaction). Put the stopper contained with the spacecraft model into the opening into which you poured the antimatter.
- Your model is now ready to launch. Give it to the TA, and the TA will mount it on the launch stand in the middle of the street. Do not distract the TA during this operation – it is critical that the launch stand be properly aligned down Jay Street so that your model will fly between the supports of the Manhattan Bridge and hit the barrier.
- One of your team members should take the Poly shuttle to the barrier so that one of you will see the launch and the other will see the end of the flight.
- When the team member has arrived at the barrier, the TA there will radio back to the launch site that they’re ready. The TA at the launch site will then press the launch switch, sending the model on its way.
- The team member at the barrier should note what happened when the model hit the barrier, and anything else of interest.
- The team member at the barrier should board the shuttle for the trip back to the launch site to meet up with the rest of their team. The team should then meet and discuss what happened so that everybody has a complete set of observations
Your lab work is now complete. Please clean up your workstation. Return all unused materials to your TA. Refer to section 3 Your Assignment for the instructions you need to prepare your lab report.
