“I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I’ll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be.__________________________________________________ “Creo en la evidencia. Creo en la observación, la medición, y el razonamiento, confirmado por observadores independientes. Creeré cualquier cosa, no importa qué tan salvaje y ridícula sea, si hay evidencia de ello. Sin embargo, lo más salvaje y lo más ridículo es algo que tendrá que ser la más firme y la más sólida evidencia.
ninguna gran mente ha existido sin un toque de locura…

Three-Dimensional Mid-Air Acoustic Manipulation
Tech demo of setup able to levitate, control and maneuver small light objects in a 3D space using ultrasound waves, defying gravity - video embedded below:
The essence of levitation technology is the countervailing of gravity. It is known that an ultrasound standing wave is capable of suspending small particles at its sound pressure nodes and, so far, this method has been used to levitate lightweight particles, small creatures, and water droplets.
The acoustic axis of the ultrasound beam in these previous studies was parallel to the gravitational force, and the levitated objects were manipulated along the fixed axis (i.e. one-dimensionally) by controlling the phases or frequencies of bolted Langevin-type transducers. In the present study, we considered extended acoustic manipulation whereby millimetre-sized particles were levitated and moved three-dimensionally by localised ultrasonic standing waves, which were generated by ultrasonic phased arrays. Our manipulation system has two original features. One is the direction of the ultrasound beam, which is arbitrary because the force acting toward its centre is also utilised. The other is the manipulation principle by which a localised standing wave is generated at an arbitrary position and moved three-dimensionally by opposed and ultrasonic phased arrays. We experimentally confirmed that various materials could be manipulated by our proposed method.
NASA released some images from the Wide-field Infrared Survey Explorer (WISE) the other day and have identified around 2.5 Million active super massive black holes (quasars) so far with the telescope scanning the entire sky. They also have1,000 candidates for the brightest galaxies discovered, these are about 100 trillion times brighter than our sun and they are dubbed “hot-DOGS” because they are dust obscured galaxies. About 2/3 of these findings are new because of dust blocking the view, and the new findings have a depth of about 10 billion light years.
