Pathria ( 1972 ) has shown, for a pressureless closed Universe, that it is inside a black (or white) hole. We show now, that the Universe with a cosmic pressure obeying Einstein’s field equations, can be inside a white-hole. In the closed case, a positive cosmological constant does the job; for the flat and open cases, the condition we find is not verified for the very early Universe, but with the growth of the scale-factor, the condition will be certainly fulfilled for a positive cosmological constant, after some time.
We invest in smart people solving difficult problems, often difficult scientific or engineering problems. Here’s why: We have two primary and related interests:

In this high-energy talk, Frans Johansson illustrates how relentless trial-and-error – coming up with an idea, executing it on a small scale, and then refining it – is THE distinguishing characteristic of the greatest artists, scientists, and entrepreneurs. Why? Because humans are not very good at predicting which ideas are going to be a success. Thus, nearly every major breakthrough innovation has been preceded by a string of failed or misguided executions. So, as Frans says quoting Churchill, “If you’re going through hell, keep going.”

A survey released this week by the Pew Research Center’s Internet and Life Project shed light on the social side of the Internet . The results offered insight into the differences between the connected and the disconnected, revealing that Internet users are more likely to be active participants, with some 80 percent of Internet users participating in groups, compared with 56 percent of non-Internet users. These findings confirm the impact of the the Internet on collective action, observed Beth Noveck , NYU law professor and former deputy CTO for open government at the White House. “Internet users are more active participants in groups and are more likely to feel pride and a sense of accomplishment.” Perhaps we are all not, as Robert D.
