What Happens if our Universe Collide with another Universe? 

How would that change the physics of our Universe? 

Is there any chance that we would survive? 

What would this collision look like from earth?

And has it ever happened before? 

This is What Happens if our universe collide with another universe and if you are looking for answers to all these amazing questions, so just stick to this article as these questions are likely to get answered here in great details.

So here is what would happen.

The any potential evidence of universal collision that we have ever discovered is in the form of cold spot in our universe. In year 2013 the European space agency's Planck satellite confirmed that this area of blue spot is 1.8 billion light years across. It is much colder than rest of space and it seems to be missing 10 thousand galaxies. At first scientists were baffled by its existence, but now some of them theorize that this part might be a scar or bruise left from colliding with another universe.

But how can we know for sure? and if this is the case how long before it happens again?

Before we go any further let me take a second to addressing something which is so puzzling. So, when we say universe we mean all the things, galaxies, black holes, time and space and anything that just exists. So, logically there would be just one universe? Well, not necessarily,  as some scientists believe in the concept of multiverse. This theory states that our universe wasn't the only one that popped into existence during the big bang. That there is infinite numbers of other universes there too. We just can not see or find a way to measure them yet.

If this theory is right then it is possible that that all these other universes could have grown at the same rate and time after the big bang. If that is the so, then they might have banged in to each other as they expanded. And that again brings us back to the cold spot. The cold spot is a region in our universe that is bit colder than anywhere else. That might not seem a big deal but rest of the universe's temperature is so consistent. Scientist have started to thinking something more than an anomaly. They think that the cold spot might be a scar left over by a collision between universes.

And a crash would have just moved a bit of energy out of that spot in our universe causing the colder temperature.

What the collision of that magnitude would look like? 

well, can't say anything for sure but there are some pretty cool ideas out there. 

According to one physicist, if another universe crashes into our universe it would look like a giant mirror in sky rushing towards us because its wall would reflect light.  If this other universe collided to our own, we could inherent a whole new set of governing laws of physics. As, gravity could weaken or disappear. Resulting in many planets escaping the gravity of their stars.

Sending them flying off in space at ridiculous speeds. Without gravity stars would cease to exist. And we would be left in perpetual dark and cold. Which would make life on earth as well as anywhere in universe nearly impossible. With no shinning stars there would be no light, and surely no planets so no oxygen. Hence, we would have no oxygen to breath.

But these are not the things to worry about as chances of our universe colliding with other ones are slim to none. For one thing, we are not so sure, that there are other universes to collide with. And if there are, then any collisions would have happened at the points when they were expanding,  380000 years after the big bang. which would means that there is little to no chance of it happening again.
