No. Einstein believed in a infinite universe.

That is impossible. A universe, whether infinite or finite is still vastly bigger than a galaxy.
The brief layman's answer: Einstein was troubled because his own theories of relativity did not support the idea of a constant universe, the universe that he preferred to believe existed. His equations showed that a steady state universe would eventually give in to the forces of gravity. He developed the cosmological constant, basically a 'fudge factor', so that his theories could support a steady-state universe. Shortly after, Hubble's redshift observations provided evidence that the universe is expanding, and Einstein called the cosmological constant the worst blunder of his life. Ironically, interest in the cosmological constant is returning, as a possible way of explaining the acceleratingexpansion of the universe.
universe is actually finite but we've not yet fond its edges, as we know that millions of planets, stars and so many kind of other bodies combined and form our galaxy, similarly millions of galaxies combined and form this huge and complex structure of our universe like unbreakable chains of molecules forming the complex structure of our body.
Scientists currently believe that no, the universe is not infinite. It is of a finite size however, this finite size is constantly expanding but not expanding AWAY from anything, just expanding
The energy of the universe is finite. It can neither be created nor destroyed. It can only change form. It is related to the concept of conservation of mass by Einstein's famous formula E=mc2 - in other words, the combined mass and energy of the universe is constant.
Einstein was essentially a Deist. He believed in a supreme intelligence of design behind the Universe, and on a question of subatomic physics, he once responded that "God does not play dice with the universe" (though he was later proven wrong in that regard). On the "personal God" level, however, he was a nonbeliever.
that portion of the universe that we can see in principle, given the finite age of the universe
The static UNIVERSE model (not a theory) holds that our Universe has been in gravitational balance for all eternity. If general relativity correctly described gravitational interaction of matter -- and Einstein DEFINITELY believed in his model -- then the Universe would have to collapse into a singularity, a fact Einstein recognized almost immediately. He thus made this collapse disappear with a wave of his hand, saying the Universe contained a force (he called it the Cosmological Constant) that perfectly balanced against a collapse by gravity. Jesuit priest George LeMaitre showed that our Universe did not need Einstein's CC if it were expanding -- an idea Einstein ridiculed. When Edwin Hubble showed that our Universe IS, indeed, expanding; Einstein admitted his CC was his "greatest blunder."
The first scientific paper on an expanding Universe with a finite age was done by Jesuit priest Georges LeMaitre. Einstein later commented on his idea: "Your math is correct, but your physics is abominable." Edwin Hubble soon showed that LeMaitre was right and Einstein was wrong.
The name Universe refers to all that there is in existence, therefore nothing can be outside it.

The number of smells is extremely large and probably incalculable. There is a finite amount of matter in the universe, thus a finite amount of olfactory sensations.
They don't.There is no certainty that the universe is finite or infinite, and indeed it may be impossible to tell. The edge of the observable universe is around 46 billion lightyears away; beyond that, it might end after a metre or it might truly go on forever. Answer2:Scintists as a community don't know. The Universe is finite with a radius around 158 Tera tera meters or 16 Billion light years away. The Universe is finite and has finite power P=3645E49 watts.
Einstein wanted to know about how the universe works.
Einstein never made any such calculation. Even today the total size of our Universe is speculative at best. Einstein speculated it was infinite in both size and age.
