And it is far denser. I see comments of this planet often making the incorrect assumption that it is in the Goldilocks zone of it's star. It is not. It can have liquid water on it's surface only because of it's very dense atmosphere making that a possibility at it's surface.

A mathematician, a physicist and an astronomer are riding a train across the Scotish countryside. The astronomer looks out the window and sees a sheep in the field. He points and says, "Look in Scotland sheep are black!" The physicist sighs and says, "Now, now. In Scotland, at least one...

I would describe the fact that some viewers believe that the witnesses, the camera people and anyone else present with Chris are not in on it, as psychology. That is the #1 point you have to accept with his shows. Every single person present is in on it. Once you accept that, it's easy to...

There's 2 ways you can specify a color, with a computer display. 1) RGB = red, green, blue 2) HSB = hue, saturation, brightness (alternately HSL or HSV) http://en.wikipedia.org/wiki/HSL_and_HSV The wiki entry explains how to convert between the 2.

But isn't it true that in a cosmological constant dominated universe that all photons are absorbed at the horizon?

In computer graphics, colors are specified with 3 numbers ranging from 0 to 255 with using RGB mode. Those numbers represents the intensity of the colors red, green and blue with three 0s meaning no intensity, hence black. Three 255s would be max intensity for each hence white.

Take a sphere of let's say, radius 10 billion light years, centred on a light bulb. Project from the centre of that sphere out to the surface of the sphere a set of lines where each passes through each atom found within the volume of that sphere. What kind of variation in density of points...

Isn't that just an assumption, that there are photons that are never absorbed? According to TI, those that would never be absorbed, are never emitted.

The answer to this question is also dependent on what else is withing your field of view. Here's an experiment we did in physics class: Have a room that can be completely darkened. Have 3 light sources of variable intensity, one red, one green, one blue. Have a 6' by 6' grid of 36...

I vote transactional. It seems the simplest and if it's good enough for Feynman it's good enough for me.

I worked as a bicycle courier for 6 years. I always went with the high gear on hills. However: - I most certainly did not get up the hill in the same amount of time. The whole point is to get to the top sooner. - I do not start the climb in a high gear at the same ground speed as I...

I first heard the answer to that question over 30 years ago: A woodchuck would chuck as much wood as a woodchuck could chuck if a woodchuck could chuck wood.

I would think F1 is force felt by object #1 and F2 is the force felt by object #2, and they are equal in magnitude, while opposite in direction. Simply multiply and divide and you are done. G x M1 X M2 / (R x R) = F1 = F2 From your post we have: M1 = 400 KG M2 = 300 KG R = 2000 M...

There are different kinds of GPS devices. The basic unit, or original design type, is as described above. It receives a time signal from multiple satellites and calculates it's position. No signal leaves the unit in your hand going back to the satellites. It's a radio...
