Create Multiple Custom Email Address with one Gmail Account

Did you know that you can create multiple email addresses with one Gmail address . Yes it is possible and not most of us are aware of the few tricks involved to achieve this. You may ask why would you need multiple email addresses for your Gmail address? Let me explain it to you.

The point here is to make multiple email address from your primary Gmail address and create unique email addresses for registering with different websites and services. In fact you can have many different email addresses for your primary Gmail address, but all the mails send to these secondary email addresses will be received in your primary Gmail addresses inbox.

This way you can create a filter for each of the custom email address associated with your Gmail account and easily organize emails from different services and websites. If in any case a website starts sending spam into your inbox , you can easily set the specific filter in your Gmail account to delete all the mails instantly when received in your inbox.

Now lets find out how we can create multiple email addresses from your Gmail address. There are two methods for creating multiple email addresses for your Gmail address.

Method 1: Using “+” annotation in your Gmail address

If you want to create multiple email addresses from your Gmail address then you can use the “+” symbol to add another word to your Gmail address. For example,

Suppose your Gmail address is and you want to create a custom email address for signing with . To create this custom email address , all you need to do is just add the keyword “amazon “ before or after your username in your email address like this “” or“” and sign up with it on Now all the emails from both these emails will be sent to your primary Gmail address .
*The + method is incredibly dangerous - this sends the email to both gmail accounts [batman+brucewayne@gmail] will go to both [batman@gmail] and [brucewayne@gmail] if you do not own both accounts someone else may get your email!
It is as simple as that and you can use this simple trick to create an unlimited number of custom email addresses and all of the mails would be send to your primary Gmail address .

Method 2: Using dots in your Gmail address 

Coming to the second method, its an less known fact about Gmail. Gmail does not care about how many dots you have in your email address. In fact it doesn’t recognize any dots within a Gmail address, which means you can place any number of dots within your Gmail address before the @ tag and Gmail will ignore the dots and still send the mail to your original mail address sans the dots. For example ,

Lets take your email address to be . If you add a dot anywhere within the words “brucewayne” , Gmail will always ignore the dots. Example you can create multiple emails address like the below :
  • and a lot more .

All these above Gmail address will still point towards your primary Gmail address at . Depending upon your requirement you can have many uses of these tricks , even you can use these tricks to update your Gmail address . Go ahead and try create as many custom email address as you would like for your Gmail address . and do let us know how this was useful to you .

Interstellar 星際效應

What Interstellar Got Right and Wrong About Science

Even a movie largely based on real science is bound to bend the rules a bit

If you’re one of the estimated 3 gajillion people who have seen or will see Chris Nolan’s blockbuster movie Interstellar, one thing is already clear to you: this is not a documentary. That means it’s fiction, specifically science fiction, which is how you get the sci and the fi in the sci-fi pairing. So if you go into the movie looking for a lot of scientific ‘gotcha’ moments, let’s stipulate up front that you’re going to find some.

That said, part of Interstellar’s considerable appeal is that it does go heavy on the science part of things. Nolan enlisted Caltech cosmologist Kip Thorne as the film’s technical adviser, and Thorne kept a whip hand on the production, ensuring that the storyline hewed as closely as possible to the head-crackingly complex physics that govern the universe.

So where did Interstellar play it absolutely straight and where did it take the occasional narrative liberty? 
Here are a few of the key plot points and the verdict from the scientists (warning, there may be spoilers ahead):

  • A worm hole could open in space, providing a short cut from one side of the universe to the other.
    Verdict: Mostly true

Worm holes are a pretty well-accepted part of modern cosmology and it’s Thorne’s theorems that have helped make them that way. The idea is that if you think of space-time less as a void than as a sort of fabric—which it is—it could, under the right circumstances fold over on itself. Punching the necessary holes in that fabric so that you could make your universe-transiting trip would be a bit more difficult. That would require what’s known as negative energy—an energetic state less than zero—to create the portal and keep it open, says Princeton cosmologist J. Richard Gott. There have been attempts to create such conditions in the lab, which is a long way from a real wormhole but at least helps prove the theory.

One bit of license the Interstellar story did take concerns how the wormhole came to be. It takes a massive object to generate a gravity field sufficient to fold space-time in half, and the one in the movie would have to be the equivalent of 100 million of our suns, says Gott. Depending on where in the universe you placed an object with that kind of mass, it could make a real mess of the surrounding worlds—but it doesn’t in the movie.

  • Getting too close to the gravity well of a massive object like a black hole causes time to move more slowly for you than it would for people on Earth.
    Verdict: True

For this one, stay with space-time as a fabric—a stretched one, like a trampoline. Now place a 500-lb. cannon ball on it. That’s your black hole with its massive gravity field. The vertical threads in the weave of the fabric are space, the horizontal ones are time, and the cannon ball can’t distort one without distorting the other, too. That means that everything—including how soon your next birthday comes—will be stretched out. Really, it’s as simple as that—unless you want to spend some time with the equations that prove the point, which, trust us, you don’t.

  • It would be possible to communicate to Earth from within a black hole.
    Verdict: Maybe

The accepted truth about a black hole is that its gravitational grip is so powerful that not even light can escape—which is how it got its name. But even physics may have loopholes, and one of them is something known as Hawking radiation, discovered by, well, guess who. When a particle falls into a black hole, the fact that it’s falling creates another form of negative energy. But nature hates when its books are unbalanced—a negative without a corresponding positive is like a debit without a credit. So the black hole emits a particle to keep everything revenue- neutral. Zillions of those particles create a form of outflowing energy—and energy can be encoded to carry information, which is how all forms of wireless communication work. That’s hardly the same as being able to radio down to Houston from within a black hole’s maw, but it takes you a big step closer.

  • It would be possible to survive the leap into the black hole from which you hope to do your communicating in the first place.
    Verdict: False—except…

Cosmologists vie for the best term to describe what would happen to you if you crossed over a black hole’s so-called event horizon, or its light-gobbling threshold. The winner, in a linguistic landslide: spaghettification—which does not sound good. But that nasty end may not happen immediately. “Most people would agree that a person who jumps into a black hole is doomed,” says Columbia University cosmologist and best-selling author Brian Greene, “but if the black hole is big enough, you wouldn’t get spaghettified right away.” That’s small comfort, but for a good screenwriter, it’s all the wiggle room you need.

  • And finally: Anne Hathaway could move through time and space and help save all of humanity and her hair would still look fabulous.
    Verdict: Who cares? We wouldn’t have it any other way.
