@EvolBob1 8 лет назад

+Michael Lolwut What Vsause didn't say was as you or any object approaches light speed, the mass increases. So even a single proton could gain the mass of a galaxy if traveling close enough to the speed of light. Same goes for a spaceship, go fast enough and your mass will increase so high your spacecraft would collapse as a Black Hole. And it is at that point you can turn on the headlights - but no one will have time for that :)

@marcozwinkels2562 8 лет назад

+Evol Bob so thats why we cant reach anywhere near lightspeed besides the factors of money and resources. Now i only need to know the point at which a ship that could achive near light speed becomes a black hole or become quite unstable because its mass would attract objects to it self.

11:55 Even though we can never reach the end of pi that doesn’t mean that after to 10^10000 digit there wouldn’t be another one. Given we are in a simulation, would the system itself not be able to provide the calculation necessary to give us that next digit in the same way that our computers could theoretically spit out the next number. Maybe pi itself was programmed in this manner so that the simulation provides what we ask of it without having its “entire value” stored?

@twally87 Год назад

interesting point. But if we live in a simulation, doesn't it seem like one that hasn't been interfered with, updated, or changed in a fundamental way since it began? Laws of physics haven't changed. Pi in particular is wrapped up with a lot of these fundamental aspects of the universe. Why would the simulation continue to emergently "create" pi as we go along (change), but nothing else? Also, the theory isn't that *in lieu* of finding pi's end it shows we **aren't** in a simulation-- only that finding the end would be strong evidence to the contrary. Put another way, not finding the 'end' of pi doesn't say much about whether or not we are in a simulation, but a finite-ness to the number would point toward us being in a simulation. Until an end to pi is found, we continue to assume it can be calculated to an infinite number of digits, and no matter how large or sophisticated a simulation computer may be, it wouldn't be capable of calculating anything infinite to insert into the 'program'.

@twally87 Год назад

maybe bc it's music with higher notes being played in reverse. The "uncanny" terror meme uses music playing in reverse for some of its creepiest sections and you might have associated that sound with fear.

@Turrican60 Год назад

There's really nothing to be terrified about, in my view. It is what it is...it's always been that way...we have to accept such things because we have no choice...and besides, we're all part of the universe in any case, as our bodies are merely 'borrowing' the atoms that comprise them. This being so, there's no point in fearing the scale of the universe, as it's merely a relative term, and nothing more.

11:12 The problem with John Gribbin's theory I feel is that numbers don't exist within our universe and are therefor not confined to it's laws. They have laws of their own, which I don't believe would change from universe to universe. However, even if they did, any computer we created to calculate Pi would only exist within the "computer" that created our simulated universe, and could therefor only calculate Pi at the speed of the program it exists within. Also, since entropy in our universe is ever increasing, I'd say if we are a simulation, we are an active simulation that is continually being written (or actively calculated), so even if numbers were confined to this universe, and even if this universe were a simulation inside some alien super computer, we may never find the end of Pi as it may still be being written infinitely "faster" than we are discovering it. That's just my theory though.

@X3nus90 9 лет назад

Also this theory is relevant only if the computer where our simulated universe running has the same architecture as our computers - which is very unlikely... If our universe is indeed running inside a computer in another universe, this computer probably has a completely different architecture based on laws of physics that don't even exist in our universe, making for us impossible to actually find elements of this architecture while living in a simulated world. :)

Yeah, all true, if they can simulate the whole of world, then they can easily simulate the irrational numbers real-time.

(Not plausible.)

@Mike23443 2 года назад

An easy explanation to this question is this: C is the speed of light, but it is also the speed at which everything in the universe travels at all times. Because C is your velocity through space, but space isn't just space. Space is spacetime. Everything travels through spacetime at the speed of C. But that speed isn't just across the physical dimensions. It includes in itself the speed with which you travel through time. An object you are holding in your hand may be traveling through space at only a few meters per second, but it is traveling through time at nearly maximum velocity, which sum of both of these will always add up to C. When you accelerate through space, you slow down through time and vice versa. You may not be able to travel at the speed of light, but if you were able to reach it, the simple explenation would be that, to you, the travel was instantenous. You can't perceive headlights going ahead of you when you turn them on, because the entirety of that travel period to you would have been a fraction of a nano second, which is already an understatement. C isn't just a speed limit. It's also a time limit, a minimum speed and a constant value all at once.

If you move backwards at the speed of light, you will see everything stand still; time stops. Because, since you are at light speed, there can not be any 'new' light entering your retinas and processing in your brain, because 'new' light can't keep up with you. So you're stuck seeing the same image; now, tomorrow, until you die, and beyond infinity (until you slow down, of course). Also, you'd need a new gearbox because reversing at that speed will overrev your engine to the fucking max.

This is exactly what I was thinking right before the theory concluded the other way. That's not the way the theory goes. The theory states that "if we do find a repeating pattern, then we would know that this is a simulation". It doesn't conclude anything about the other outcome, which is where your wild imagination is going. So the theory's conclusion still stands. In other words, you just countered a point that the theory didn't even suggest.

according to special relativity: at .999c, from your point of view, the headlights will work fine, but traveling so fast causes the world outside to stretch out for you and for time outside to seem to be ticking way faster than it normally does. for an outside observer at rest, the headlights also still work fine- but you are now moving way slower, with length contraction sizing your car down extremely thin and with time slowing down for your car as seen by the observer as well. the reason the headlights work in both scenarios (both observers) essentially lies on the foundations of the theory of special relativity. light travels at a constant speed through a vacuum regardless of inertial frame of reference. nothing can exceed the speed of light, including light itself, neither for you (the traveler) nor the observer. thus, to keep the speed of light constant in both windows of reference, length and time are changed proportionally as to preserve c as a constant.
