How long does an infectioned mosquito have to bite you before it transmits a disease such as malaria or dengue? Is it as soon as it bites you or until it's full. Thank you!

Everything I can find says red aurora is due to low concentrations of oxygen at higher altitude, whereas green aurora is due to higher concentrations at lower altitude. That's quite an unsatisfying explanation though.

What exactly is the mechanism for exciting different wavelengths at different altitudes?

Across disparate mountain ranges, the tallest peaks are all in the 14,000s in height. From rainier in the cascades at 14410, to Whitney in the Sierra Nevadas, and all the 14ers in Colorado - why does there seem to be an elevation limit?

If chromosome fusion occurs as a single event in one generation, and organisms with different numbers of chromosomes generally don't produce viable offspring, then who would this organism with newly fused chromosomes produce offspring with?

For example, in the human genome when chromosome 2 formed from the fusion of two other chromosomes, who did this newly fused unique organism mate with?

Is it simply that they usually don't produce viable offspring but in some rare cases they do? If so, then maybe this fusion happened more than once and it took many attempts at offspring before it caught on and a viable offspring was produced?

For example: TON 618 is 18.2 billion light years away from Earth, requiring 18.2 billion years for the light to travel to our eyes. The universe is only 13.7 billion years old. But, we can still see it. Even if TON 618 was created at the very inception of the universe, that still leaves 4.5 billion years of light travel unaccounted for. What am I missing?

An article talks about a weakened version of the flu virus in a vaccine.

How is the virus weakened?

Removing some parts of the virus? Or stressing the virus? Or something else?

The idea and question is really about the feasibility of creating a solar highway and who knows maybe more. Essentially what we would do is capture large asteroids and put them on a continuous loop that would go around earth and then back to mars for example. We set up 20 of them or whatever and then to travel to mars you don’t have to fly all the way there you just fly up and latch on to the asteroid that’s coming by every month or two. They could be dug out and essentially be giant ships. The question part is this even mathematically possible to have an object get in this kind of orbit? Is it possible to go up and catch it without many issues? Is it too hard to slow down on approach? Thanks!

Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary Science

Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...".

Asking Questions:

Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists.

Answering Questions:

Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience.

If you would like to become a member of the AskScience panel, please refer to the information provided here.

Past AskAnythingWednesday posts can be found here. Ask away!

I guess this is also a question about all hurricanes but considering the amount of oil spilled here- does this mean that oil from past leaks and spills will be sprayed everywhere?

And also is there a chance of underwater sea cables for internet being torn up?

How deeply will the hurricane affect the ocean? Or is it only going to damage the topmost layer of water?

As of right now, it looks as if Milton will pass right over the peninsula of Florida, but what will happen to it when it reaches the Atlantic Ocean? Since hurricanes typically build strength when they’re over the Atlantic Ocean and then head towards the interior of the US, with this one headed into the ocean instead, what will it do? Will it just get stronger and stronger as it crosses the Atlantic until it obliterates all of Europe? Will it curve back and hit the east coast? Or will it just fizzle out over the ocean? Everywhere I’ve looked talks about what Milton will do to Florida, but nowhere seems to talk about what will happen to it after it passes over Florida.

There are various forms of energy, including heat energy, chemical energy, electrical energy and light energy etc.

How do we distinguish them on an quantum scale? Are there any arrangements of particles which result in various forms of energy?

We have determined that galaxies are held together by gravity that is much stronger than the sum of their mass would suggest. We use dark matter to explain this. Is this model accounting for the energy within the galaxy? Since energy and mass are the same thing sort of (e = mc2,) this energy should exert gravity too. Yes, energy would have a much much weaker gravitational pull than mass, but think of how much energy is in a whole galaxy. Think of all of the angular momentum and motion of all the millions of stars and black holes in the whole system. Would the net of all of this gravity help hold the galaxy together, with the barycenter at Sagittarius A*?

Not trying to debunk dark matter or anything, just trying to learn about physics!

Really curious if on average what mountain would erode faster. This assumes same material and average conditions for there environment.

I've seen hurricanes regain strength in the Gulf but never form and get so strong. Just curious if this is unusual.

Ovens, microwave, fire, there are plenty of ways to make something nice and hot but not cold (besides refrigerator). Could we invent a cold oven or cold fire?

I know that usually particles will be stripped from a comet approaching a star and the tail will be pushed away from the star by the stellar wind. But I also remember learning somewhere that when a comet gets especially close to a star, gasses and liquids will be heated and expelled specifically from the side of the comet facing the star in great enough volumes that they will overcome the pressure of the solar wind, resulting in a tail that faces towards the star instead. Is this latter theory possible?

Are scientists actively studying rabies somehow, anywhere? How? Do they infect animals with it and study them? ... Study how?

Sorry if my question is non specific, but I will try to specify here. If a black hole has a singularity with truly infinite gravity, and gravity gets weaker with distance, then isn't it impossible to divide/subtract a number from infinity, without that number being zero or inifnity, but we know we can't do that anyways, so whats the deal, shouldn't the gravitational energy that is supposedly infinite, continue radiating into space, destroying space time in it's wake? Or are singularities truly not infinite gravity? Sorry if this sounds stupid, I am simply trying to understand this as the average joe.

I know it will eventually make its way to the ocean, but in the mean time, does it move along the course of the various rivers like an egg in a snake – a swollen, flooded area all the way down?
