Nothing at all. Halley's Comet has had no physical effect on the world. There would still be hundreds of other comets in orbit, and we'd still be seeing bright lights in the sky.
About the only effect of Halley's Comet was that it was a fairly short-period comet that even the relatively primitive astronomers of the time could tell was regularly repeating. Someone else, a little later, would have come to the inevitable conclusion.
What else can I help you with?
What will happen if pizza never existed?
Nothing would happen. If pizza never existed, we would simply be eating something else.
In what year was the last time halleys comet was 10 miles above the earth?
Halley's Comet has never been 10 miles above Earth. It is always millions of miles from us, even when closest to us. It was last visible from Earth in 1986. It will next be visible in 2061.
What if the world never existed?
Who knows what would happen?
What would happen if chocolate never existed?
people would be really sad
What if Antarctica never existed?
If Antarctica never existed, then it never would have existed.
Why did the oston tea party happen?
There has never existed anything known as the oston tea party.
When was the hale-bopp comet and haleys comet visible together?
Never.
What would happen if the sun were a blue star?
I think that it would be to hot to live on earth and we would have never existed
What would happen if America didn't win the Spanish-American War?
The world as we know it would never have existed.
What year will the next comet hit Earth?
If the U.S. Air Force and NASA have anything to say about it, never. There are probably a hundred thousand comets out in space that we've never seen because the LAST time they approached the Sun was before man existed, or had invented writing; in either event, we have no record of it. Sooner or later, a comet will fall into the solar system on a collision course with the Earth. We know this WILL happen - we just don't know WHEN. So scientists are slowly working out ways to intercept or deflect or destroy such a comet. It probably won't happen for a thousand years or more. But the Earth is about 4 billion years old, and will probably exist for that much more. The Earth has been hit many times before. It WILL happen again. We need to start preparing now.
What things might be happen without computers?
Is the question what might happen if computers suddenly ceased to exist, or is the question what might happen had computers - computer science and technology as we currently know it - never existed at all?
Is it humanly possible to see a comet twice?
Yes, it is possible for a comet to be visible from Earth more than once if it has a return orbit. Some comets have orbital periods that bring them back around and make them visible multiple times in a human lifetime.
