  • Misconceptions About the Universe

    Can we see things travelling faster than light? Check out Audible: http://bit.ly/AudibleVe Music by Amarante "One Last Thing" http://bit.ly/VeAmarante Awesome animations by http://youtube.com/minutephysics Thanks to Prof. Geraint Lewis for input on earlier drafts of this video. The expanding universe is a complicated place. During inflation the universe expanded faster than light, but that's something that actually happens all the time, it's happening right now. This doesn't violate Einstein's theory of relativity since nothing is moving through space faster than light, it's just that space itself is expanding such that far away objects are receding rapidly from each other. Common sense would dictate that objects moving away from us faster than light should be invisible, but they aren't. ...

  • A Certain Train Is Traveling At a Constant Rate

    For this problem we are going to set up a proportion, then cross multiply to find out how many hours the train will travel in y miles (Distance: s miles)/(Miles: t hours)= (y miles)/(?hours)  (s miles)/(t hours)=(y miles)/(?hours)  (s)(?)= ty  ?= ty/s. So our answer is C.

  • Interstellar Travel: Approaching Light Speed

    Is interstellar travel doomed to remain in the realm of science fiction? Sticking to near future space propulsion only, how close can we get to the speed of light? This video looks at the current spacecraft speed records with Apollo 10 holding the record for the fastest manned spacecraft, New Horizons probe for the fastest Earth escape velocity and the Helios probes for the fastest heliocentric velocity. But Solar Probe Plus will beat that when it launches in 2018. While Voyager 1 doesn't set any speed records, it was the first spacecraft to leave the solar system, so therefore the fastest solar system escape velocity by default. For beating these speeds, this video explores what is possible in the near future only, so no antimatter, Alcubierre drives (warp), ramjets, etc... The EM drive...

Can we see things travelling faster than light? Check out Audible: http://bit.ly/AudibleVe Music by Amarante "One Last Thing" http://bit.ly/VeAmarante Awesome animations by http://youtube.com/minutephysics Thanks to Prof. Geraint Lewis for input on earlier drafts of this video. The expanding universe is a complicated place. During inflation the universe expanded faster than light, but that's something that actually happens all the time, it's happening right now. This doesn't violate Einstein's theory of relativity since nothing is moving through space faster than light, it's just that space itself is expanding such that far away objects are receding rapidly from each other. Common sense would dictate that objects moving away from us faster than light should be invisible, but they aren't. This is because light can travel from regions of space which are superluminal relative to us into regions that are subluminal. So our observable universe is bigger than our Hubble sphere - it's limited by the particle horizon, the distance light could travel to us since the beginning of time as we know it.

For this problem we are going to set up a proportion, then cross multiply to find out how many hours the train will travel in y miles (Distance: s miles)/(Miles: t hours)= (y miles)/(?hours)  (s miles)/(t hours)=(y miles)/(?hours)  (s)(?)= ty  ?= ty/s. So our answer is C.

Is interstellar travel doomed to remain in the realm of science fiction? Sticking to near future space propulsion only, how close can we get to the speed of light? This video looks at the current spacecraft speed records with Apollo 10 holding the record for the fastest manned spacecraft, New Horizons probe for the fastest Earth escape velocity and the Helios probes for the fastest heliocentric velocity. But Solar Probe Plus will beat that when it launches in 2018. While Voyager 1 doesn't set any speed records, it was the first spacecraft to leave the solar system, so therefore the fastest solar system escape velocity by default. For beating these speeds, this video explores what is possible in the near future only, so no antimatter, Alcubierre drives (warp), ramjets, etc... The EM drive is left out until it's proven with actual reproducible results in space. Project Daedalus and the updated Project Icarus represent sound concepts for fusion spacecraft. IKAROS was the first successful demonstration of solar sail technology but hopefully the planetary society is not far behind with their LightSail cubsat (not covered in this video). But what appears to have the most potential to reach the nearest star to our own, Proxima Centauri and it's newly discovered planet Proxima b is Breakthrough Starshot. Thousands of super lightweight laser sail nanocraft will be launched into space then the light beamer, a ground based laser array will propel these spacecraft to 20% light speed within minutes. *All sources used in researching this video are listed in the end credits* Music: "Inspired" Kevin MacLeod (incompetech.com) Licensed under Creative Commons: By Attribution 3.0 License http://creativecommons.org/licenses/by/3.0/

These 3 things go "faster" than the speed of light. How's that even possible? Subscribe: http://www.youtube.com/channel/UCj1gf...Want more info?↓ More about the experiment: Marissa Giustina’s research: http://arxiv.org/abs/1511.03190 Advanced scientific note about Doppler: If there is a light moving away from you at constant velocity in static flat (Minkowski) space-time, no matter how red it is, you will never conclude it is going faster than light. But, here I am discussing the conclusions one might come to if you mistakenly use Doppler in the context of the curved space-time of the universe (where there is expansion). Interpreting the huge redshift as a result of the doppler effect, could make one think that galaxies we see are moving away at speeds approaching light speed. And since what we are actually seeing is light from those galaxies from billions of years ago, and given that the universe is expanding, you might be tempted to say that they have since "accelerated" to faster than the speed of light. You might go further and say that there are more distant galaxies that we can't see which are moving away even faster. So you might conclude there are galaxies moving faster than light in the universe. But the redshift isn't from doppler and this "acceleration" of the expanding universe isn't actually causing a true increase in velocity. Sometimes astronomers do say there is a faster than light "recession speed" by pretending the expansion of the universe is causing distant galaxies to move away from each other at a corresponding velocity, but that's misleading. In general relativity, you can actually have an increase in space between objects without causing a corresponding increase in the relatives velocities of those objects.

On the quantum mechanical level, atoms have dual personalities, just like photons of light." What is the Inflation Theory? http://wmap.gsfc.nasa.gov/universe/bb_cosmo_infl.html "The Inflation Theory proposes a period of extremely rapid (exponential) expansion of the universe during its first few moments.

PROPAGATION OF ELECTROMAGNETIC WAVES:In communication using radio waves, an antenna at the transmitter radiates the Electromagnetic waves EM waves, which travel through the space and reach the receiving antenna at the other end. As the EM wave travels away from the transmitter, the strength of the wave keeps on decreasing. Several factors influence the propagation of EM waves and the path they follow. At this point, it is also important to understand the composition of the earth’s atmosphere as it plays a vital role in the propagation of EM waves. A brief discussion on some useful layers of the atmosphere is given in Table. Ground wave: To radiate signals with high efficiency, the antennas should have a size comparable to the wavelength of the signal at least /4. At longer wavelengths i.e., at lower frequencies, the antennas have large physical size and they are located on or very near to the ground. In standard AM broadcast, ground based vertical towers are generally used as transmitting antennas. For such antennas, ground has a strong influence on the propagation of the signal. The mode of propagation is called surface wave propagation and the wave glides over the surface of the earth. A wave induces current in the ground over which it passes and it is attenuated as a result of absorption of energy by the earth. The attenuation of surface waves increases very rapidly with increase in frequency. The maximum range of coverage depends on the transmitted power and frequency less than a few MHz. Sky waves:In the frequency range from a few MHz up to 30 to 40 MHz, long distance communication can be achieved by ionospheric reflection of radio waves back towards the earth. This mode of propagation is called sky wave propagation and is used by short wave broadcast services. The ionosphere is so called because of the presence of a large number of ions or charged particles. It extends from a height of ~65 Km to about 400 Km above the earth’s surface. Ionisation occurs due to the absorption of the ultraviolet and other high-energy radiation coming from the sun by air molecules. The ionosphere is further subdivided into several layers, the details of which are given in Table. The degree of ionisation varies with the height. The density of atmosphere decreases with height. At great heights the solar radiation is intense but there are few molecules to be ionised. Close to the earth, even though the molecular concentration is very high, the radiation intensity is low so that the ionisation is again low. However, at some intermediate heights, there occurs a peak of ionisation density. The ionospheric layer acts as a reflector for a certain range of frequencies 3 to 30 MHz.Electromagnetic waves of frequencies higher than 30 MHz penetrate the ionosphere and escape. These phenomena are shown in the Figure. The phenomenon of bending of EM waves so that they are diverted towards the earth is similar to total internal reflection in optics.

http://facebook.com/ScienceReason ... Albert Einstein's Theory of Relativity (Chapter 3): Space-Time And The Speed Of Light The concept of spacetime combines space and time to a single abstract "space", for which a unified coordinate system is chosen. Typically three spatial dimensions (length, width, height), and one temporal dimension (time) are required. Dimensions are independent components of a coordinate grid needed to locate a point in a certain defined "space" --- Please subscribe to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceMagazine • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- SPACETIME In physics, spacetime (or space-time) is any mathematical model that combines space and time into a single continuum. Spacetime is usually interpreted with space being three-dimensional and time playing the role of a fourth dimension that is of a different sort from the spatial dimensions. According to certain Euclidean space perceptions, the universe has three dimensions of space and one dimension of time. By combining space and time into a single manifold, physicists have significantly simplified a large number of physical theories, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels. In classical mechanics, the use of Euclidean space instead of spacetime is appropriate, as time is treated as universal and constant, being independent of the state of motion of an observer. In relativistic contexts, however, time cannot be separated from the three dimensions of space, because the observed rate at which time passes for an object depends on the object's velocity relative to the observer and also on the strength of intense gravitational fields, which can slow the passage of time. • http://en.wikipedia.org/wiki/Spacetime --- GENERAL RELATIVITY Special relativity is a theory of the structure of spacetime. It was introduced in Albert Einstein's 1905 paper "On the Electrodynamics of Moving Bodies" (for the contributions of many other physicists see History of special relativity). Special relativity is based on two postulates which are contradictory in classical mechanics: 1. The laws of physics are the same for all observers in uniform motion relative to one another (principle of relativity), 2. The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the source of the light. The resultant theory agrees with experiment better than classical mechanics, e.g. in the Michelson-Morley experiment that supports postulate 2, but also has many surprising consequences. Some of these are: * Relativity of simultaneity: Two events, simultaneous for one observer, may not be simultaneous for another observer if the observers are in relative motion. * Time dilation: Moving clocks are measured to tick more slowly than an observer's "stationary" clock. * Length contraction: Objects are measured to be shortened in the direction that they are moving with respect to the observer. * Mass-energy equivalence: E = mc2, energy and mass are equivalent and transmutable. * Maximum speed is finite: No physical object or message or field line can travel faster than light. The defining feature of special relativity is the replacement of the Galilean transformations of classical mechanics by the Lorentz transformations. (See Maxwell's equations of electromagnetism and introduction to special relativity). • http://en.wikipedia.org/wiki/Theory_of_relativity .
