Shadow Sculptures by Tim Noble and Sue Webster
At each moment, light (as well as electromagnetism and gravitational force) is coming towards you from every direction, in a sphere around you. The light has left its location at different times, from the Moon; 2 seconds ago, the Sun; 8 minutes ago, Vega; 25 years ago, Andromeda; 2 million years ago and so on. You could imagine a set of concentric spheres, each one containing a part of the universe you are experiencing. The greater the radius of the sphere, the farther back in time you experience that part. In the diagram this is represented as the âpast light coneâ; each âsphereâ becomes a circular slice of that cone. The present moment of each location in spacetime is the focused intersection or standing wave pattern of all waves and forces originating within the past light cone of that location. Likewise, all electromagnetic and gravitational waves and forces traveling into the future of the present are âdispersedâ relative to the observer by the inverse square law; intensity is proportional to 1/(distance²). For example, all the light the bounced off of a pterosaur 200 million years ago and passed through Earths atmosphere is still out there, traveling, 200 million light years away. It is incredibly diffuse, you would need to construct a telescope billions of light years across to create an image, but the information still exists.Â
For forces that travel at light speed, we only experience and effect the surface of the light cones. Matter, which travels at less than light speed through space, influences us and is effected by us within the volume of the light cones. All matter and forces travel at light speed, but in different dimensions. Light is restricted to space dimensions, and does not experience time. Matter travels at light speed primarily through time, and can also travel through space relative to other objects. To maintain light speed, matter will move less through time, giving rise to relativistic effects such as time dilation. Here I will cite "The Fabric of the Cosmos" by Brian Greene, an excellent book that shaped my thinking on this subject.
The implications of light cones are incredible. At each moment your body is being influenced by the volume of the entire universe, in a gradient from moments ago to the big bang. The size of the effect is mediated by the inverse square law, so the closest things effect you the most. However if one star in the andromeda galaxy, 2 million years ago, disappeared, there would be a minute change in the gravitational pull on the atoms of your body. Perhaps a salt ion in one of your neurons wouldnât exit an ion channel, and your thoughts and life would be different. This effect goes forward into time as well, every action we take effects everything in out future light cone. As beings, we are completely integrated into the Universe, composed and created by every event in our past light cone, and manifesting everything in our future light cone.

Thriving since 1960, my garden in a bottle: Seedling sealed in its own ecosystem and watered just once in 53 years.
âTo look at this flourishing mass of plant life youâd think David Latimer was a green-fingered genius. Truth be told, however, his bottle garden â now almost in its 53rd year â hasnât taken up much of his time. In fact, on the last occasion he watered it Ted Heath was Prime Minister and Richard Nixon was in the White House.
For the last 40 years it has been completely sealed from the outside world. But the indoor variety of spiderworts (or Tradescantia, to give the plant species its scientific Latin name) within has thrived, filling its globular bottle home with healthy foliage.
Yesterday Mr Latimer, 80, said: âItâs 6ft from a window so gets a bit of sunlight. It grows towards the light so it gets turned round every so often so it grows evenly. âOtherwise, itâs the definition of low-maintenance. Iâve never pruned it, it just seems to have grown to the limits of the bottle.âÂ
The bottle garden has created its own miniature ecosystem. Despite being cut off from the outside world, because it is still absorbing light it can photosynthesize the process by which plants convert sunlight into the energy they need to grow.â
So how does it work exactly?
âBottle gardens work because their sealed space creates an entirely self-sufficient ecosystem in which plants can survive by using photosynthesis to recycle nutrients.
The only external input needed to keep the plant going is light, since this provides it with the energy it needs to create its own food and continue to grow.
Light shining on the leaves of the plant is absorbed by proteins containing chlorophylls (a green pigment).
Some of that light energy is stored in the form of adenosine triphosphate (ATP), a molecule that stores energy. The rest is used to remove electrons from the water being absorbed from the soil through the plantâs roots.
These electrons then become âfreeâ - and are used in chemical reactions that convert carbon dioxide into carbohydrates, releasing oxygen.
This photosynthesis process is the opposite of the cellular respiration that occurs in other organisms, including humans, where carbohydrates containing energy react with oxygen to produce carbon dioxide, water, and release chemical energy.
But the eco-system also uses cellular respiration to break down decaying material shed by the plant. In this part of the process, bacteria inside the soil of the bottle garden absorbs the plantâs waste oxygen and releasing carbon dioxide which the growing plant can reuse.
And, of course, at night, when there is no sunlight to drive photosynthesis, the plant will also use cellular respiration to keep itself alive by breaking down the stored nutrients.
Because the bottle garden is a closed environment, that means its water cycle is also a self-contained process.
The water in the bottle gets taken up by plantsâ roots, is released into the air during transpiration, condenses down into the potting mixture, where the cycle begins again.â

Acoustic Levitation
Using sound waves to levitate individual droplets of solutions containing pharmaceutical drugs and drying them in mid-air. Why do this? This is useful because most of the drugs on the market are either amorphous or crystalline and the crystalline form doesnât get absorbed by the body. So levitating the solution allows the drug to be made into an amorphous state (by evaporation) because if it were to touch any surface it would simply crystallize. They call this âcontainerless processingâ.
The frequencies used are just above the audible range at about 22 kilohertz and when the two speakers are aligned they create two sets of sound waves, perfectly interfering with each other creating a phenomenon known as a standing wave. This allows the objects to levitate in areas within the waves known as nodes as the acoustic pressure is enough to cancel the force of gravity.

A lab has created negative temperatures? HOW IS THAT POSSIBLE?!
Record Temperature Set: Colder than Absolute Zero: âThe inverted Boltzmann distribution is the hallmark of negative absolute temperature, and this is what we have achieved,â said researcher Ulrich Schneider, a physicist at the University of Munich in Germany. âYet the gas is not colder than zero kelvin, but hotter. It is even hotter than at any positive temperature â the temperature scale simply does not end at infinity, but jumps to negative values instead.â

First âHeartlessâ Man: You Donât Really Need A Heart, Or A Pulse
Two doctors Billy Cohn and Bud Frazier from the Texas Heart Institute successfully replaced a dying manâs heart with a deviceâproving that it is possible for your body to be kept alive without a heart, or a pulse. In the short film âHeart Stop Beatingâ by Jeremiah Zagar of Focus Forward Films, Zagar documents the process of the doctorsâfrom cutting out the whole heart of 50 calves and replacing it with centrifugal pumps, to finally implanting it into their patient Craig Lewis. The turbine-like device, that are simple whirling rotors, developed by the doctors does not beat like a heart, rather provides a âcontinuous flowâ like a garden hose. After the doctors experimented on one of the calves, Abigail, Doctor Cohn told NPR: âIf you listened to her chest with a stethoscope, you wouldnât hear a heartbeat. If you examined her arteries, thereâs no pulse. If you hooked her up to an EKG, sheâd be flat-lined.â Craig Lewis was a 55-year-old, dying from amyloidosis, which causes a build-up of abnormal proteins. The proteins clog the organs so much that they stop working, according to NPR. But after the operation, with the âmachineâ as his heartâs replacement, Lewisâ blood continued to spin and move through his body. However, when doctors put a stethoscope to his chest, no heartbeat or pulse can be heard (only a âhummingâ sound)âwhich âby all criteria that we conventionally use to analyze patientsâ, Doctor Cohn said, he is dead. This is proof that âhuman physiology can be supported without a pulseâ.

Body suit may soon enable the paralyzed to walk: An international research team announces it has taken a key step toward achieving its goal of a âprosthetic exoskeletonâ that a quadriplegic could command by brain power. They demonstrated that they could bypass the bodyâs complex network of nerve endings and supply the sensation of touch directly to the brains of monkeys. Doing so with humans is their next objective.

How Futurama Gets Science Right (Sort Of)
Bender, the hard-drinking, kleptomaniac, aspiring folk singer robot, sure hates to work about as much as he loves himself. In the episode âBenderama,â Bender avoid doing âtwo thingsâ â folding two sweaters â by simply doing one thing: making two smaller copies of himself using a new invention by the Professor. To make the smaller clones, however, Bender has to ingest an equal amount of matter from which to build the mini-Benders. Complications ensue when the mini-Benders make their own copies in an infinite series that threaten all of Earthâs resources. This scenario is actually based on a doomsday scenario dubbed âgray gooâ first proposed by author and nanotechnology expert K. Eric Drexler. In his book âEngines of Creation: The Coming Era of Nanotechnology,â Drexler examines a scenario in which automated nanotechnology created self-replicating machines that would eventually use up all of Earthâs resources.
