Please don't end.

Dear world,

Could you raise c by a factor of 299.7? It will be very much appreciated.

I second that.

I like your taste in colours. Blue and green go well together. :)

A nice side-effect includes, "faster-than-light," travel becoming non-relativistic, but you do realize that that could result in random explosions because the M:E exchange rate would be about 8e21 as opposed to the current 9e16, right?

What's M:E? And how could that cause random explosions? Please explain, I need to know for a spacecraft design I'm working on.

E=γmc^2 where γ=1/√(1-v^2/c^2). For stationary objects, γ=1 because 1/√(1-0/c^2)=1. If c (about 3e8 in the real world) was increased, matter-to-energy conversions would be more energetic but energy-to-matter conversions would consume more energy. M:E is the ratio of mass to energy for a certain amount of mass-energy. A higher value of c would decrease the ratio because mass could be converted to more energy. The sun converts under 1% of its mass into energy and it is already harmful to some extent here (UV-skin cancer). Imagine what would happen if it spontaneously produced a lot more energy continuously.

About the spaceship, the main rule is that even the photon cannot exceed c, the speed of light. If c was multiplied by 299.7 (arbitrary random number between 0 and 9999 divided by ten), then going at 3e8 m/s would not be exceeding the speed of light. In fact, it would be the equivalent of going at 3e-3 c, or 3e6 km/h, which is not too bad. However, you might want to ask someone who has had spacecraft as a specific special interest, because my knowledge of astronomy tends to be restricted to planetary data and predicting the movements of the moon, the sun, and the other stars (other stars excludes the moon). My last attempts with spacecraft specifically involved a nice gaming sourcebook from an unusually detailed and precise (quite accurate as well) company.

"the photon cannot exceed c, the speed of light"

That is in a vacuum, particles has been observed traveling faster than c through a medium. So just fill the universe with X medium and you are there.

The main problem is that media of any kind kind tend to slow matter on the, "macro," scale. It would be simpler in theory just to increase c.

So there are theories like string theory and M theory that attempt to explain why c is the way it is. Do we know which one is right?
P.S. there's a U in your signature.

U? Where? :)

As for theories like string theory and M theory, if there was a unanimous consensus on which one was correct, there would be plenty of media (as in nouvelles media) covering the event and the researchers involved would certainly be chosen for the Nobel Prize. The simplest answer is that there is not enough information. [Note that I am inexperienced in this field and nothing more than a high-school senior, but there are probably more than a few members specializing in this.]

If you are inventing for fiction (or conworlding!), try one and use it consistently. For me, I just invented an implausible system in which everything experiences four dimensions and time is a separate existence called the tempace (a space analogue) but still equivalent to any spatial dimension, meaning one could, "rotate," π/2 to switch a temporal and a spatial axis.

Let the Russian space junk rest for 10 minutes before carving. :twisted:

You're pretty cold today.
