Science Explained: What is the Hottest Possible Temperature?

Science Explained: What is the Hottest Possible Temperature?

Talking about the coolest possible temperature seems relatively simple. The coldest of the cold is absolute zero. As you may know, movement causes friction, which causes heat. As such, absolute zero is, in essence, when all movement stops. The temperature is reached at -459.67 degrees Fahrenheit (-273.15 degrees Celsius). We’ve come pretty close to reaching this temperature. Most recently, scientists at the Massachusetts Institute of technology (MIT) cooled molecules to just 500 billionths of a degree above absolute zero.
But what about the hottest possible temperature? Is there an absolute hot?
absolute zero
MIT cooled sodium potassium (NaK) molecules to a temperature of 500 nanokelvin. Here, the NaK molecule is represented with frozen spheres of ice merged together: the smaller sphere on the left represents a sodium atom, and the larger sphere on the right is a potassium atom.

Well, things aren’t really that simple. Stopping all movement is one thing, but how do we measure maximum movement? How do we take energy up to infinity? Theoretically, it is possible. But theory isn’t necessarily what we observe in our physical reality.
As such, it seems that the highest possible known temperature is 142 nonillion kelvins (1032K.). This is the highest temperature that we know of according to the standard model of particle physics, which is the physics that underlies and governs our universe. Beyond this, physics starts to breakdown. This is known as Planck Temperature.
If you are wondering, the number looks a little like this: 142,000,000,000,000,000,000,000,000,000,000 (that’s a really big number). Ultimately, this can only come about when particles achieve what is known as thermal equilibrium. In order for it to be the hottest temperature, physicists assert that the universe would have to reach thermal equilibrium, with a temperature that is so hot, all the objects are at the same temperature.
The closest that scientists think we ever came to this temperature is, unsurprisingly, just after the Big Bang. At the earliest moments of our universe, spacetime expanded so fast (a period known as the inflationary period) that particles were unable to interact, which means that there could be no exchange of heat. At this juncture, scientists assert that, for all intents and purposes, the cosmos had no temperature.
No heat exchange. No temperature.

But this quickly ended. Scientists assert that, just a fraction of a fraction of a fraction of a second after our universe began, spacetime started to vibrate, which caused the universe to come to about 10,000,000,000,000,000,000,000,000,000 (1027) Kelvins.
And our universe has been growing and cooling since this moment. So. It is believed that this moment, which occurred just after the start of our universe, is the hottest moment in the universe, the time at which the hottest temperature that will ever be reached was.
Just for comparison, the hottest temperature that we have ever actually encountered is in the Large Hadron Collider. When they smash gold particles together, for a split second, the temperature reaches 7.2 trillion degrees Fahrenheit. That’s hotter than a supernova explosion.

Explainer: The nico-teen brain

Explainer: The nico-teen brain The adolescent brain is especially vulnerable to the addictive effects of nicotine BY  TERESA SHIPLEY FELDHAUSEN 7:00AM, AUGUST 19, 2015 Nicotine (black triangle towards center left) tricks the nerve cell (neuron) into sending a message to release more dopamine (yellow dots). Those molecules enter the space (synapse) between one nerve cell and the next. When they get picked up by neighboring cells, this gives users a feel-good high. It also creates the risk of addiction and other health problems.  EMail Print Twitter Facebook Reddit Google+ NATIONAL INSTITUTE ON DRUG ABUSE, ADAPTED BY J. HIRSHFELD Nicotine is the addictive chemical in tobacco smoke and e-cigarette vapors. And doctors say the teenage brain is no place for it to end up. Nicotine can reach the brain within seven seconds of puffing on a cigar, hookah, cigarette or electronic cigarette.

fix idm integration on chrome

Chrome Browser IntegrationI do not see IDM extension in Chrome extensions list. How can I install it? 
How to configure IDM extension for Chrome?Please note that all IDM extensions that can be found in Google Store are fake and should not be used. You need to install IDM extension manually from IDM installation folder. Read in step 2 how to do it.

1. Please update IDM to the latest version by using "IDM Help->Check for updates..." menu item

2. I don't see "IDM Integration module" extension in the list of extensions in Chrome. How can I install it?

Press on Chrome menu (arrow 1 on the image), select "Settings" menu item (arrow 2 on the image) and then select "Extensions" tab (arrow 3 on the image). After this open IDM installation folder ("C:\Program Files (x86)\Internet Download Manager" by default, arrow 4 on the image) and drag and drop "IDMGCExt.crx" (arrow 5 on the image) file into "Extensions" page opened in…
