Einstein-Rosen Bridge
Einstein-Rosen Bridge aka. Wormholes are theoretically developed feature of Space-Time it was theorized on the basis of Einstein's General Relativity solutions. Wormholes is just a hypothetical feature and there are no evidences of its existences. But surely General Relativity predicts it mathematically, and there are chances of its existence but it has been found that it can exist only at the Planck Scale (Energy Scale).
What are Wormholes? How does it look like?
Wormholes are basically is passage through two different space-time that could create shortcuts for long journeys across the universe. To picturize this Try folding an A-4 size paper and make a hole at the center with the help of a pencil. Now unfold it and see the point of holes. For instance name the first hole A and the second hole B. If you are living in A and want to meet you friend who is living in B, you will have to walk quite a distance. But if you were to create this Wormhole (i.e fold the paper again) you would have reached B. i.e The point A and B will interest. And those two points are linked with a help of a wormhole. Its just like a long tube but allows you to travel much faster than the usual route. Science Fiction writers are fascinated with this theory and they almost frequently use them in their stories. In fact you can actually link this to the great novel Alice in the Wonderland written by Lewis Carroll ; The Rabbit Hole that Alice can actually be thought as a wormhole which led to another universe (Multiverse).
Multiverse Theory
Multiverse theory is also an hypothetical set that compresses infinite or maybe possible set of universes similar to a huge hamburger stuffed with infinite or maybe finite cheese layers. These type of universes are also called the parallel universe. And strangely according the quantum theory there might be a possibility in which Elvis might be still living and rocking out, or maybe time much be running backwards i.e Entropy( Degree of Disorderness) might decrease with time. Constants might differ in different universe due to that there might not be life forms in some universes. Strangely in our Universe the constants are perfectly tuned in a way that life could form that doesn't mean we are lucky its just an accident that happened and if it didn't we wouldn't have been able to evolve and ask questions about the universe.
I know that these theories are strange and hypothetical but it has the mathematical proof behind it , as far as that holds experimental researches and theoretical development on that particular theory will continue. In fact the most strange theory ever known to mankind is the Quantum Theory in which strange things happen. For example: Wave-Particle Duality; Light being an electromagnetic wave acts both as wave and particle. This particular theory is certainly strange and different from what we perceive in our world. How could something act both at the same time. Check out Dual-split experiment for more information on Wave-Particle Duality.
These bizarre things happen almost every time in the quantum world and it seems strange to us because we are part of the macroscopic world. Surely if we could shrink ourselves with a cosmic quantum crusher (Made-up name) we could turn into a size of an electron and experience all this by ourselves.
In fact even-though Quantum theory seems strange it has be tested over and over again and has not been proved wrong even once. All the technologies which we use in our world: From the TV's / Computers to Microchips everything works under the workings of Quantum Mechanics.
Mathematics is the only language which helps physicists to understand the universe. Without the help of math, it would be impossible for any scientist to deduce the nature. Math is logic. Even-though these theories might seem bizarre it will certainly might become a fact one day. Just like how Nicolas Copernicus theory (The Earth and the other planets are orbiting the sun and not the other way around) is an obvious fact now.
"Pure Mathematics is, in its way, the poetry of logical ideas." - Albert Einstein
"Everything is becoming science fiction. From the margins of an almost invisible literature has sprung the intact reality of the 20th century." - J.G. Ballard
