If the "big bang" theory is true, why does Venus spin backwards?

All planets would spin the same way if the big bang really happened.

http://www.nasa.gov/audience/forstudents/k-4/home/...

Update:

Well it just makes sense that every planet would spin the same way. If everything has an equal and opposite reaction, then all things that were started by one "bang" would have the same reaction and therefore have similar characteritics. i.e. rotate the same direction, not totally out of sinc with all else.

Update 2:

Calling me an idiot is hardly an answer.

Update 3:

The two drops of water though not travelling at the same speed were traveling the same direction... i.e. away from the "cause" of their movement. And the rest of your answer is complete speculation, therefore no answer at all.

Update 4:

Venus spinning backwards is a fact, not speculation. If we want to speculate as to why..., one could also speculate that God spun that one planet backwards to confuse those that want to "speculate" otherwise... Wouldn't that be just as good as any other speculation since no one truly knows?

Update 5:

Again even Wikipedia is speculating. In the last sentence of the Widipedia comment it says, "could have"... Key words that are used many times and normally overlooked by most. "Could have" is speculation... a guess. It's just as reasonable to say "couldn't have."

Update 6:

How does anyone KNOW the universe is 14 Billion yrs. old. Again speculation, a guess. And not even a good one at that. There is no scientific answer to this ? so give it up... Only God knows!

Update 7:

Apparently the last post is supposed to "prove" that the universe is in fact nearly 14 billion years old, but again there is no facts that absolutely prove anything on the site. They can only speculate that what they are saying is true, but the truth is no one knows for sure. And they have the gall to call me naive...?

    lol... the big bang theory....

    what a joke!

    Ok, so you didn't like that, huh. Well tell me something... If you put a broken glass in a paper bag and shook it up for a while, what are the chances that glass is going to come out of there in one piece? NONE!! The universe was not created by a big "bang", as you say. It is hardly logical, in fact, I dare say it is ridiculous! It is easier to believe that there is a God and He created the universe, rather than to believe it all came together by random chance.

    I don't get it, I mean I don't get your question.

    The Solar System is about 4.5 billion years old. The Big Bang was about 13.7 billion years ago. So between the two you have 9.2 billion years.

    A lot of things can happen in 9.2 billion years.

    The way the solar system came to be, you had a cloud, which ended up as a disk, rotating in a certain direction around a certain axis. Then the disk coalesced into a star, and planets. There were lots of shocks, and some of these were so great, that Venus ended up rotating the other way (and Uranus has its axis tilted 90 degrees, and the Earth's is tilted 23 degrees, actually all the planets' axes are tilted a bit, because of those collisions).

    Your question is a bit like saying, "oh I found two droplets of water not traveling at the same speed, so they cannot have come from a wave crashing on a jetty".

    Why could they? The planets all coalesced from the same cloud of dirt approximately 5 billion years in the past. That replaced into not the massive bang; planet formation isn't any massive secret through fact we are able to watch the entire technique around different stars. the massive bang is what created a lot older nebulae that collapsed into stars that then died, exploded, and released out clouds of distinctive factors for planets and 2nd and 0.33 era stars (jointly with our own) to form from. Now, asking why some planets in our image voltaic gadget have funky spins in the event that all of them formed up from the same dirt cloud is a valid question and that i think of this is what you meant. all of them spin around the sunlight interior the same course yet Uranus is on this is area and Venus is unquestionably spinning backwards very slowly. There are some theories approximately tidal locking however the main ordinary explanation for Venus is that this is spinning backwards through fact something hit it very, very stressful. The planets did not coalesce suddenly. as quickly as that they had quite often formed there could have been smaller protoplanets nonetheless flying around, and prefer the spins struck poolballs each and every each and every now and then acquire issues have been given jostled around. by the way that's in all probability the place Earth's moon got here from. We have been given hit by using something approximately as great as Mars different than somewhat of screwing up our spin (nicely, perchance slightly, we do not likely be attentive to why we've seasons the two) it merged with Earth at a especially good clip and gouged out a extensive quantity of fabric that grew to grow to be the moon. This replaced into not a nicely-liked concept until human beings introduced back moon rocks and scientists have been waiting to accomplish a planetary paternity try; the moon's composition is purely too close for it to be thoroughly unrelated. The early image voltaic gadget does not have been a secure place.

    The universe is about 14 billion years old. No orbit is circular, no sphere is perfect, probably no axis is at absolutely 90 degrees to the orbital plane.

    All kinds of things can happen in 14 billion years. And the big bang hardly demands that every single planet spin in the direction of it's orbit. Sorry.

    To quote Dawkins:

    I love how people take a theory (X) that explains nothing and find one thing that they don't understand about the world and immediately replace theories that explain a LOT with their X theory.

    Apparently you have had enough answers to your original question, so I will address another of your questions that you posted in the "Details" section. You say:

    "How does anyone KNOW the universe is 14 Billion yrs. old. Again speculation, a guess. And not even a good one at that. There is no scientific answer to this ? so give it up... Only God knows!"

    Unfortunately, such a statement on your part does nothing but demonstrate your inexcusable naivety and unwillingness to research a matter before you speculate on it. The universe is, in fact, precisely 13.7 billion years old, and all the hard, scientific evidence you want can be found on this page and on the pages to which it links:

    Have a nice day.

    Some sort of meteor/comet/asteroid impact could affect the rotation of the planet if the object was big enough and fast enough.

    Wikipedia has this:

    If viewed from above the Sun's north pole, all of the planets are orbiting in an anticlockwise direction; but while most planets also rotate anticlockwise, Venus rotates clockwise in "retrograde" rotation. The question of how Venus came to have a slow, retrograde rotation was a major puzzle for scientists when the planet's rotation period was first measured. When it formed from the solar nebula, Venus would have had a much faster, prograde rotation, but calculations show that over billions of years, tidal effects on its dense atmosphere could have slowed down its initial rotation to the value seen today.

    I've noticed that you've discredited an answer based on speculation, but in such a case as the formation of the solar system/universe, most answers you'll find are based on speculation. There's no way for us to ever know for sure, as we weren't there to experience it, and there's little available evidence to support anything. All we really can do is take what knowledge is already known about basic planetary formation and whatever bits of evidence we can find and try to create a coherent theory out of it. Speculation is harder to avoid than you think in such a field.

  • 1 decade ago

    No one knows for sure, but they think that a very large asteroid many years ago crashed into it sending it spinning backwards. Since it's going against it's gravity and original spin, it spins very slowly and a day on Venus is longer than a year. There are many theories about it, but that's the most popular theory. It did in fact start by spinning normally.

  • 1 decade ago

    Your question is a logical fallacy. I recommend during further research in General Relativity and Hawkins theory's. You will see very little correlation between the "big bang" and the formation of our solar system.

    You obviously have a feeling that the big bang is not right and you are trying to show that by your question. But how can you disprove the big bang if you don't understand it. You must learn all you can, then you will be much better and proving it wrong.

    And how do you figure that? I'm really curious as to why you'd think that each planet would have to rotate the same direction to coincide with the big bang theory, lol.

    *sits back and grabs popcorn*

    This should be interesting.
