Admin Contrary to the suggestion of the question, a space ship would not stop when it runs out of fuel. Even though there are objects in space like gas, dust and particles, they are in such low concentrations and so spread out that it is highly unlikely that a space ship would come into contact with … Read more What could a space ship do if it stopped because it ran out of fuel?
To answer this question, we first have to think about how we actually define what a planet is. In space we have different ways of characterizing the astronomical bodies, and of differentiating them from one another.Is there a way to define what a planet it?In science, numbers play the largest role because they are exact … Read more Is Pluto a planet?
Although it is true that the universe is expanding at a rapid rate, this expansion of the universe does not affect our galaxy in the ways you might think.How galaxies are affected by universe expansionOur galaxy is made up of astronomical bodies, all of which orbit other objects and have a set path that has … Read more How long before the expansion of the universe causes our earth to drift away from the sun?
To begin with, there is no amount of water that you can throw at the sun to ‘put it out’. Throwing water on the sun would actually make the sun burn even more.Isn’t the sun like a giant fire?The sun’s process is nuclear fusion, not chemical combustion which means that it is not a regular … Read more How large would a bucket have to be to put out the sun?
Actually, the wind is not the only factor that causes ocean currents. It is true that the wind plays a role, but it is only a small one compared to some of the other variables involved. On top of this, the factors that we are about to explain, including wind, act in different ways on … Read more How does the wind create all the ocean currents?
What is a photon?A photon is a particle of light. Or, more specifically, it is a particle that represents light. A photon will carry energy.Can a photon travel at the speed of light?Since a photon is a particle of light, this means that it does not need to accelerate to light speed, as it is … Read more How does a photon accelerate to light speed so quickly?
To answer the second part of this question first: black holes do not suck everything in. Some objects can actually orbit black holes just like the earth orbits the sun: safely. This is possible because black holes have their own gravity just like our sun does, or like stars do in general. In fact, stars … Read more How can there be anything left in the universe? Don’t black holes suck everything in?
The basicsThe heart does not actually work on its own to pump blood all the way around the body, this is because there would be a high amount of pressure at the area of the heart and a significantly lower pressure at the extremities. So, imagine blood being pumped away from your heart to the … Read more How can the heart be strong enough to pump blood up your legs against gravity?
The simple answer is no, gravity does not extend out forever. Although there is a theory that states that it does.Newton’s Law of Universal GravitationNewton’s law states that the force of gravity on one mass due to another mass will depend mainly on their separation. This separation is represented as r where the dependence is … Read more Does the influence of gravity extend out forever?
This is an example of a question that has been influenced by science fiction literature and movies that seem to warp the truth on things like this for entertainment. But also, the science itself can be confusing. This answer will debunk the incorrect beliefs that we hold and also explain why they are wrong.So, do … Read more Does every black hole contain a singularity?
