Facts about Universe

Astronomers think space might be infinite, with "stuff" (energy, galaxies, etc.) distributed pretty much the same as it is in the observable universe. If it is, that has some seriously weird implications for what lies out there. Beyond the Hubble Volume you won't just find more, different planets.May 6, 2011

The universe was already far too big to understand. But scientists just found that it's actually much bigger than we'd previously thought. The observable universe is made up of at least two trillion galaxies, according to a new study.Oct 14, 2016

With at least 200 billion galaxies out there (and possibly even more), we're very likely talking about a Universe filled with around 1024 planets, or, for those of you who like it written out, around 1,000,000,000,000,000,000,000,000 planets in our observable Universe.Jan 5, 2013

Our Solar System consists of our star, the Sun, and its orbiting planets (including Earth), along with numerous moons, asteroids, comet material, rocks, and dust. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy.

Here are the few differences between cosmos and universe : 1. Cosmos” is a whole harmonious and orderly system that is governed by natural law while “universe” is everything that exists including time and space, matter, and the laws that govern them. 2.

Cosmos is the opposite of Chaos, which was the first state of the universe. Nowadays they are used like synonyms; they refer to the same thing, but seen from different "point of views". ... "Cosmos is a Greek word for the order of the universe. It is, in a way, the opposite of Chaos.Apr 12, 2011

The short answer is that this is a nonsense question, the Universe isn't expanding into anything, it's just expanding. The definition of the Universe is that it contains everything. If something was outside the Universe, it would also be part of the Universe too.Nov 28, 2013

Gravity is the weakest force as its coupling constant is small in value. Gravity cannot be felt by us in daily life because of the huge universe surrounding us. Electromagnetic force is undoubtedly stronger as it deals with microscopic particles (electrons, protons). Gravity is always attractive in nature.Jan 31, 2011

Largest Planet. Located in the constellation Hercules, planet TRES4 is 70% larger than Jupiter in diameter, but has only 80% of Jupiter's mass. Because of how close it orbits to its sun, it is thought that the intense heat expand the gasses that make up this planet, resulting in an almost 'marshmallow-like' density.Mar 5, 2011

Venus is the hottest planet even though Mercury is the closest planet to the Sun. The reason that Venus is hotter than Mercury is because it has an atmosphere made of carbon dioxide; it also has clouds of acid inside its atmosphere. This is called greenhouse effect.
