Nearly a century ago, Edwin Hubble’s discovery of red-shifting of light from galaxies in all directions from our own suggested that space itself was getting bigger. Combined with insights from a handful of proposed non-Euclidean geometries, Hubble’s discovery implied that the cosmos exists in more than the three dimensions we’re familiar with in everyday life.That’s because parts of the cosmos were moving further apart, yet with no physical center, no origin point in three-dimensional space. Just think of an inflating balloon seen only from the perspective of its growing two-dimensional surface, and extrapolate to four-dimensional inflation perceived in the three-dimensional space that we can see. That perspective suggests that three-dimensional space could be curved, folded, or warped into a 4th dimension the way that the two dimensional surface of a balloon is warped into a 3rd dimension.We don’t see or feel more dimensions; nevertheless, theoretical physics predicts that they should exist.
There are three practical implications:
1. Warp Drive The main theory here is called M theory, which is a theory in physics that unites various types of what’s called superstring theory. In M theory there 10 or 11 dimensions. In addition to the three we’re familiar with there are compact dimensions. It’s all related to phenomena called branes that vibrate like strings, but what’s most relevant to this discussion is that the extra or compact dimensions don’t necessarily have to remain compact and it might be possible to unpack the extra dimensions. If an advanced civilization learns how to manipulate higher dimensions, they might use them for technology, including warp drive. The idea being that some kind of controlled decompacting of extra dimensions could have the effect of squeezing or expanding one of the three big dimensions that we know. Engage the compacting effect in front of a starship and the expansion effect to the rear, and you’d have warp drive. So far, we don’t have a shred of evidence that the hypothesized extra dimensions even exist. Someday, soon, we might get some evidence from the Large Hadron Collider.
3. Traversable Wormholes Another means of transport made possible by a multidimensional cosmos is wormholes. Theoretical physicist Kip Thorne worked out the equations showing that there was a stable, traversable wormhole, or even a system of such tunnels linking different areas of space-time. An advanced civilization could build a system of wormhole-dependent tunnels connecting different points of the space-time fabric, essentially drawing the departure and arrival points in the fabric into close proximity to one another through a 4th dimension. If we could do it, we could have an entry portal nearby, somewhere in the inner Solar System, that leads to an exit point at our destination, for instance a nearby star system with an Earth-like planet.
The two brightest planets Venus and Jupiter are to appear so close in the sky in the upcoming nights that they will be seen like a single super bright star, which some astronomy-lovers say resembles the biblical ‘Star of Bethlehem’.
“Throughout the month of June 2015, the two brightest planets in the night sky, Venus and Jupiter, are going to converge for a close jaw-dropping encounter,” said NASA in a news release.
“For unmeasurable periods, I seem divorced from my body, as though I were an awareness spreading out through space, over the earth and into the heavens, unhampered by time or substance, free from the gravitation that binds to heavy human problems of the world. My body requires no attention. It’s not hungry. It’s neither warm or cold. It’s resigned to being left undisturbed. Why have I troubled to bring it here?” ― Charles A. Lindbergh
