For the first time, scientists worldwide and at Penn State University have detected both gravitational waves and light shooting toward our planet from one massively powerful event in space — the birth of a new black hole created by the merger of two neutron stars.
When exposed to pulsed laser light, the gold evaporated, producing a powerful shock wave in the colloid comparable to that caused, say, by the impact of a micrometeorite.
The pulsar's rotation is thought to slow because the neutron star's powerful magnetic field acts as a giant dynamo, emitting light, radio waves and other electromagnetic radiation as the star rotates.
Pulsars, those spinning, superdense neutron stars that send powerful lighthouse beams of radio waves and light flashing through the Universe, have been lying about their ages.
Pulsars, those spinning, superdense neutron stars that send powerful «lighthouse beams» of radio waves and light flashing through the Universe, have been «lying about their ages,» leading astronomers, and possibly particle physicists, to erroneous conclusions for the past 30 years, according to researchers using the National Science Foundation's Very Large Array (VLA) radio telescope.
, you are lying on the floor of your place looking up, a small draft runs through the room, between the door and the window, and all things seem perfectly still, wind only disturbs concrete in imperceptible ways, or it may take millions of years to be noticed and, as the air runs through the space, all your plants move and all is animated and all is alive somehow, and here are the thoughts of all men in all ages and lands, they are not original with me, and that wind upon your plants is the common air that bathes the globe, and we have no ambitions of universalism, and I'm glad we don't, but the particles of air bring traces of pollen and are charged with electricity, desert sand, maybe sea water, and these particles were somewhere else before they were dragged here, and their route will not end by the door of this house, and if we tell each other stories, one can imagine that they might have been bathed by this same air, regrouped and recombined, recharged as a vehicle for sound, swirling as it moves, bringing the sound of a drum, like that Kabuki story where a fox recognizes the voice of its parents as a girl plays a drum made out of their skin, or any other event, and yet I always felt your work never tells stories, I tend to think that narrative implies a past tense, even if that past was just five seconds ago, one second ago was already the past, and human memory is irrelevant in geological time, plants and fish know not what tomorrow will bring, neither rocks nor metal do, but we all live here now, and we all need visions and we all need dreams, and as long as your metal sculptures vibrate they are always in the Present, and their past is a material truth alien to narrative, but well, maybe narrative does not imply a past tense at all and they are writing their own story while they gently move and breathe, and maybe nothing was really still before the wind came in, passing through the window as if through an irrational portal to make those plants dance, but everything was already moving and breathing in near complete silence, and if you're focused enough you can feel the pulse of a concrete wall and you can feel the tectonic movements of the earth, and you can hear the magma flowing under our feet and our bones crackling like a wild fire, and you can see the light of fireflies reflected in polished metal, and there is nothing magical about that, it is just the way things are, and sometimes we have to raise our voice because the music is too loud and let your clothes move to a powerful bass, sound waves and bright lights, powerful like the sun, blinding us if we stare for too long, but isn't it the biggest sign of love, like singing to a corn field, and all acts of kindness that are not pitiful nor utilitarian, that are truly horizontal as everything around us is impregnated with the deadliest violence, vertical and systemic, poisonous, and sometimes you just want to feel the sun burning your skin and look for life in all things declared dead, a kind of vitality that operates like corrosion, strong as the wind near the sea, transforming all things,
In one room, it consists of a black super-directional parabolic loudspeaker that projects a pure wave of sound into the white space; in the other room, a powerful searchlight projects a beam of white light into the black space.
The bigger photons / particles / waves such as thermal infrared (near infrared is classed with visible as Light, Reflective, not Heat, Thermal), are big enough and powerful enough to move the whole molecule into vibration, it's too big for electronic transitions.
Perhaps you should take a break from this and go and sit outside in the fresh air and relax in the big powerful waves of invisible longwave infrared heat direct from the Sun warming you up inside and look at the benign, restful visible light from the Sun making the sky blue as it is bounced around all over the place by the molecules of air in the atmosphere.
The molecule will first use the heat energy in expansion and on cooling will again condense and sink because heavier, and it will cool when its heat expanded volume flows to colder air which absorbs the heat, the internal kinetic energy of vibration, which if strong enough will pass that heat to another colder (which is why visible light is not a thermal energy, it is not powerful enough to move a molecule of matter into vibration, it takes the bigger heat wave, longwave infrared, aka thermal infrared called that because it is the wavelength of heat)-- that is how convective heating warms the fluid gas air in a room, by circulation, in the rise and fall of molecules as they expand and condense, not by heat energy propelling molecules to hit other molecules..
Shorter wavelengths though more energetic does not mean that they are therefore more powerful in penetrating matter, they are much weaker than the longer waves depending on the make up of the matter as more likely to get reflected and scattered because of their tiny size, and here, my point, is that the Solar energy balance graphic is wrong, because it has reversed the properties by giving Light energies the ability to penetrate and heat matter which is the actual, real, property of Thermal IR.
