Messages From The Stars Speed Up



Subspace communication, subspace radio, or hyperchannel, was the primary form of electromagnetic communication used throughout the Federation. By transmission of a subspace radio signal, which traveled through subspace rather than normal space, subspace communication permitted the sending of data and messages across interstellar distances faster than the speed of light. This made it much more practical than conventional radio. In fact, starships rarely even monitored frequencies that traveled at the speed of light. (TNG: "The Ensigns of Command", okudagram; VOY: "The 37's")




messages from the stars speed up



The speed of subspace messages varied greatly depending upon the technology involved. For instance, in the 2260s, a subspace message from the Romulan Neutral Zone took three weeks to reach Starfleet Headquarters, whereas a century later, at the same distance, subspace communications were essentially in real time. (TOS: "Balance of Terror", Star Trek Nemesis). A message traveling subspace over a distance of 2.7 million light years would have taken fifty-one years and ten months to reach Federation space in 2364. (TNG: "Where No One Has Gone Before")


Orders and reports were not the only communications to and from starships. Personal messages were also sent. The crew of Enterprise, for example, received personal messages from friends and family members back on Earth. Captain Jonathan Archer himself received recordings of water polo tournaments in what Trip Tucker described as the "subspace mailbag". (ENT: "Vox Sola")


By the 23rd century, subspace communication was in wide use throughout the Federation. (Star Trek: The Original Series) During this time, a starship's communications officer was required to create subspace logs detailing all messages sent and received. (TOS: "The Man Trap")


The message was broadcast into space a single time via frequency modulated radio waves at a ceremony to mark the remodeling of the Arecibo Telescope in Puerto Rico on 16 November 1974.[1][2] The message was aimed at the current location of M13, about 25,000 light years from Earth, because M13 was a large and relatively close collection of stars that was available in the sky at the time and place of the ceremony.[3] When correctly translated into graphics, characters, and spaces, the 1,679 bits of data contained within the message form the image shown here.[4]


The content of the Arecibo message was designed by Frank Drake, then at Cornell University and creator of the Drake equation, who wrote the message with help from Carl Sagan and others.[1] The message was meant more as a demonstration of human technological achievement than a serious attempt to enter into a conversation with possible extraterrestrials.[1] As globular cluster M13, at which the message was aimed, is more than 25,000 light-years from Earth, the message, traveling at the speed of light, will take at least 25,000 years to arrive there. By that time, the core of M13 will no longer be in precisely the same location because of the orbit of the star cluster around the galactic center.[1] Even so, the proper motion of M13 is small, so the message will still arrive near the center of the cluster.[5]


You can probably guess that starred items are important, but you may not know that you can use stars to flag important messages in Thunderbird and then call them up again later. Thunderbird's star feature can help you speed up your workflow and keep you organized by placing important messages a click away.


The Starred messages folder remains empty until you put something in it. You can do that by adding a star to an important message you'd like to flag. Stars are more than visual indicators that help you find your favorite messages easily. Mozilla designed the user interface so that stars are clickable icons that perform useful tasks.


The user interface makes it easy to star a message. Click one of the white stars next to a message, and Thunderbird turns it yellow. The message becomes a starred message. Click the star again to turn it white and "unstar" the message; the star icon functions like a toggle that enables you to star and unstar a message at will. Sorting email messages can help you save time by grouping them by category. Click the "Subject" column header, and Thunderbird sorts messages by subject. You can also click the star header to sort messages by star color. When you click the star header, yellow starred messages come to the top of the list and white messages that are not starred go to the bottom.


The speed up may not be as significant if sending compressed rendered graphics over the internet is not the bottleneck slowing the response. This may be the case when the model is very large (more than 10 million computational cells). For very large models running on many compute nodes, some experimentation will be necessary to determine if connecting a STAR-CCM+ client from a local machine to a very large job on the cluster provides significant speed up in the user interface.


Thanks to this decoupling, rendering of OffscreenCanvas is fully detached from the DOM and therefore offers some speed improvements over the regular canvas as there is no synchronization between the two. What is more, though, is that it can be used in a Web Worker, even though there is no DOM available. This enables all kinds of interesting use cases.


In this episode of the Marketers Take Flight podcast, I dive into the power of ChatGPT, a cutting-edge language model that can help AEC marketers speed up their content creation efforts. I discuss 10 different ways to use ChatGPT to help with content creation, including generating thought leadership content, writing social media posts and captions, developing content for landing pages and website pages, and creating personalized email messages. Additionally, I share five ways to use ChatGPT for proposals, such as generating bio summaries and writing technical descriptions.


Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away. (Or about 268,770 AU.) When we talk about the distances to the stars, we no longer use the AU, or Astronomical Unit; commonly, the light year is used. A light year is the distance light travels in one year - it is equal to 9.461 x 1012 km. Alpha Centauri A & B are roughly 4.35 light years away from us. Proxima Centauri is slightly closer at 4.25 light years.


One of the most accurate methods astronomers use to measure distances to stars is called parallax. If you hold your finger in front of your face and close one eye and look with the other, then switch eyes, you'll see your finger seem to "shift " with respect to more distant objects behind it. This is because your eyes are separated from each other by a few inches - so each eye sees the finger in front of you from a slightly different angle. The amount your finger seems to shift is called its "parallax".


Stars are not actually stationary objects! The Galaxy is rotating, and the stars are in orbit around its center. Not every star moves at the same rate - how fast they orbit can depend on where the star is located within the Galaxy. Our Sun, being fairly far from the Galactic Center, takes over 200 million years to circle the Galaxy once. Some of the stars near us are moving faster than us, and some slower. As Phil Plaitt, from Bad Astronomy says, "...like cars on a highway, stars continually pass each other as they orbit the Galaxy. They change positions, slowly, but measurably."


The Voyager 1 spacecraft is on an interstellar mission. It is traveling away from the Sun at a rate of 17.3 km/s. If Voyager were to travel to Proxima Centauri, at this rate, it would take over 73,000 years to arrive. If we could travel at the speed of light, an impossibility due to Special Relativity, it would still take 4.22 years to arrive!


Select from the list the CAN device and a channel on the device you want to receive CAN messages from. This field lists all the devices installed on the system. It displays the vendor name, the device name, and the channel ID. The default is the first available device on your system.


Mail that arrived after the crash, including mail from Cornell users to other cornell.edu addresses, eventually went through but was held on Cornell mail hubs and fed back to the postoffices after the system was restored. For a few days, "Your mail has not yet been delivered" messages were almost as common as spam. "This is merely a warning. There is no need for these messages to be sent again," CIT announced. "The messages are in queue and will be delivered."


Despite being the most massive spiral galaxies in the universe, super spirals are actually underweight in stars compared to what would be expected for the amount of dark matter they contain. This suggests that the sheer amount of dark matter inhibits star formation. There are two possible causes: 1) Any additional gas that is pulled into the galaxy crashes together and heats up, preventing it from cooling down and forming stars, or 2) The fast spin of the galaxy makes it harder for gas clouds to collapse against the influence of centrifugal force. 041b061a72
