The universe is so, extremely giant, it's pretty much impossible to actually imagine how big it really is. The best thing to do is to start with something small and work up from there; so let's start with the Earth. Earth may seem a giant place to us humans, but no where near in size to the universe. But, at approximate, the Earth is about 8,000 miles wide. If you drove a transglobal tunnel down through the middle of the Earth (which is not possible, but just imagine it) at a non - stop speed of 60mph, then you'd pop out the other side in about 5.5 days. Which isn't that long with what will come up. Now, lets try the distance to the Earth to our Moon. Every month, the Moon will get further and closer away from us. But, on average, the distance from Earth to Moon is 240,000 miles. Travelling at a speed of 60mph, you'd get to the Moon in about 168 days, which is quite long. Now, lets try something even longer; the Earth to the Sun. This distance is about 92 million miles, and would take you about 176 years to get there by 60mph. Now, to cross our galaxy, the Milky Way. By going at 60mph, you'd have to travel 621 million billion miles to cross the Milky Way. It would take 1 million billion (or, to be more precise, 1,181,401,000,000,000) years to accomplish. So, this tells us that a space car would be pretty cool, but 60mph is a pathetic speed for travelling across space. So, we'll think of something super - duper fast; light. The speed of light can travel a mind - blowing 186,000 miles in 1 second, at approximate. We're talking about a speed so fast it could travel 6 trillion miles if it kept on moving at it's normal speed for 1 year. This is known as a 'Light year'. But, even with our super fast speed of light travel, it'd take it about 100,000 years at approximate to cross the Milky Way. And, to move onto our universe. With out most powerful telescopes, we can measure that the universe is 15 billion Light years in every direction. So, at the speed of light, it'd still take at least 30 billion years to cross the universe.
For a conclusion, it's pretty much impossible to measure out the proper size of the universe.
It never ever ends. It goes on and on and on ........
It is theorized to be infinite but there is no way to know with our technology because we can only see a certain distance using different types of technology.
The expansion of every part of our Universe was as big as our Universe -- which, if not infinitely large, is pretty big.
The universe formed from big bang!!!
The Universe was formed by the Big Bang
The Big Bang Theory tells what happen at the begning of the universe. How the Earth comes into the universe
No. Universe A expands from a 'Big Bang' stops expanding, and contracts until there is a 'Big Crunch'. Then there is a new big bang and the beginning of Universe B, a middle, and another big crunch, a big bang with Universe C and so on. At the time of any 'big crunch', all matter and energy from that universe ceases to exist. It cannot manifest itself until after the next 'big bang', and then has no relation to anything in its previous manifestation.
There was no Universe (or time) before the Big Bang.
According to the big bang theory the universe began about?
Our universe is expanding
Scientists believe the "first event" in the Universe was the Big Bang. The Big Bang Theory attempts to explain how the universe was originally created.
The universe came into existence with the Big Bang, so asking how big it was before that is meaningless.
It happened in the center of the universe, for which it is still expanding on the universe.
The big bang was the BEGINNING of the universe so there was no temperature before it :P
Big Bang is believe to be origin of the universe without willing for creation. By believing in Big Bang, it mean believe it just happen by nature. It is not universe is create by Big Bang but Universe or Galaxy or Planet earth are consequence from Big Bang.
The universe is so big and it will never be completely populated because it includes areas that are unlivable. The Earth is part of the whole universe.
It wasn't. The Big Bang was the beginning of the universe; the universe didn't exist before then.
The condensed universe itself, at the big bang.
Big bang, and God creating the Universe.
the pulsating universe theory is when the universe expands (the big bang) then contracts (the big crunch) and so on (it's pulsating). according to this theory right now the universe is expanding, but then it will contract
the universe is bigger than the galaxy because our galaxy (the milky way) is in the universe.
Well I do now one theory about the universe. It's the big bang theory. The big bang theory is a theory about how the universe was created.Scientist think that a big explosion created the universe.Scientist found lots of evidence that the big bang theory was true.
The big bang theory proposes that the universe came from the point that was singularity , it states that after the bang the universe started expanding thus it explains everything that how was universe how and why it is expanding ,what happened after the big bang
Our concept of the "big bang" has no explanation about how or why, but our hypothesis is that there was NOTHING before the Big Bang created the universe.
The size of the universe expanded after the big bang and is still expanding today. The temperature of the universe has lowered and has been distributed throughout the universe.
Not much, really. Our Universe MIGHT be significantly larger than what we can see -- that portion of our Universe we call the "observable Universe" -- or it might be infinite. No conclusion can be made about the size of our Universe based on the fact of the Big Bang.
The Big Bang Age of the Universe is around 13.5 to 14 Billion Years.For those who do not believe in the Big Bang, I estimate the Universe to be around 16.4 Billion Years.
