By the theory of relativity there is the concept of proper speed; the speed of observer in respect of the supposed isotropic environment. This speed can limit arbitarily near to infinity and light speed in these kind of frame can be said to be infinite. One of the important campsites in lewis and harris lessons of modern computers is that a single state space is capable of sustaining an indefinitely number of virtual worlds — virtual frames — that seem just as real as the primary world. We do this kind of context-based virtualization all the time on smart phones. For the universe version, the only catch is that virtualization would have a resource cost.
There are reduced advisory speed limits for some roads during poor weather. Speeding fines are doubled in construction zones and designated safety corridors, with signs often stating this. There are no longer night speed limits, nor are there any differential speed limits for heavy trucks. The common limited access freeway speed limit is 65 mph. However, shorter length freeways such as US 202, Route 15, Route 90, and Route 33 remain at 55 mph. In all 65 mph speed zones, the fines for speeding and other moving violations are doubled.
There is no paradox as long as you realize that we do, for better or worse, have an arrow of time. I “believe” that the present is a kind of a mirror (made out of fast-as-light particle), were faster-than-light particle and slower-than-light particle actualize. And negative energy in form of a particle – could be seen as an imaginary mass. So a positron could be a kind of a tachyon particle with nevertheless positive Energy (~ minus x minus). However, quantized properties are characterized by inner symmetries and have nothing in common with properties in the usual sense that can be understood as physical qualities inherent in things. The isospin of the nucleons or the “color” of the quarks no longer express any qualities in this sense, but only arbitrarily defined basic states or directions in an abstract space that are related to each other through symmetry transformations.
In general, you can convert from km/h to mph by dividing the speed in km/h by 1.6. Since the drive uses how fast the rider is pedalling to decide how much drive is released, it can be manipulated to think otherwise. If you desire to go above the speed limit of 25 km/h, then all that has to be done is to make the electric bike system think that you are going at a slower rate even though you are going at a very high speed.
Theoretical physicists are used to discuss abstract objects based on mathematics. A thought experiment will not tell you if you made useful assumptions. If something math-based makes real sense the “best proof” would be an application based on ones “thinking how it could be done”. But thinking about c as a fundamental constant, a property of nature, it seems to say that there is a constant, built-in so to speak, relationship between spatial distance and time. And talking about anything traveling faster is another example of talking about north of the north pole. Are there any inertial frames in which the two are always aligned even for spacelike separated events?
Speeding can reduce the amount of time you have to react to an unexpected obstacle. It decreases your ability to adjust to curves and turns in the road. For any two reference frames which say two things happened at the same time, there is another which says it didn’t. Also, two reference frames observing a third reference frame may disagree on the order of events. According to classical relativity, velocity is a relative concept. ____________ are the most frequent victims of collisions between vehicles and pedestrians.
The U.S. Department of Transportation was directed to withhold highway funds from states that did not adopt a maximum speed limit of 55 mph. Before that, speed limits on rural interstates in most states ranged from 65 to 75 mph, with the majority of states setting rural interstate speed limits of 70 mph. In urban areas, most states maintained 55 mph speed limits before the national maximum speed limit was established. Colorado now allows higher speeds on rural highways and directed the state Department of Transportation to prioritize raising speeds on roads connecting rural towns to cities, schools and other heavily traveled corridors. The department will set higher speed limits on rural highways if it determines that such increases will not endanger public safety. Mississippi increased the speed limit for school buses transporting students on interstate highways from 50 to 65 mph.
Though FTL would be hard to deal with numerically as an IVP, as I had mentioned in the other comment. The source of a sound vibrates bumping into nearby air molecules which in turn bump into their neighbours and so forth. This results in a wave of vibrations travelling through the air to the eardrum which in turn also vibrates. Space is really, really big, and aliens are not magic. These are the two critical points to consider if you really want to think about UFOs as spacecraft from distant star systems.
