I know this is crazy but is this even possible? Because if we knew exactly how strong the pull is you could possibly find out how to avoid them.

Is it possible to put two solar power satellites in space to capture more sunlight ? Maybe you can install a battery to the satellite then store the energy for 100 years then plug the battery up to a power plant?

Is it possible that we are already inside a black hole and the dark matter all around us is the "Mush" that remains after the singularity?

Is it possible to adjust a rocket ship while in space? If so we could study the Kupier belt and see exactly. How long it is so we can know exactly how high to adjust the ship before entering the belt and avoid hitting asteroids to reach the outer parts of space instead of going right through the belt and risking a crash.

Such as gravitational, centrifugal, etc? I'm sure you can and scientists already have, I'm just having trouble finding information and would greatly appreciate if anyone could give me some credible references?

Hi everyone, I have a very unique question I thought can be answered by science! I watched a movie called the Truman Show and in the movie he wants to go to Fiji and he is on a reality tv show that keeps him in this bubble. Now I was wondering if it is scientifically possible to fake a plane ride so he thinks he is going from that place he lives to Fiji. Or is it impossible to simulate it because you can look out the window and see everything and you can really notice where you are and stuff. I would assume you would fly the plane above the clouds and while above in the clouds the set designers change the area up and then the plane comes back down and lands in th…

i have an led tv , before some time when i was sitting in front of it [and it was off] i saw a colour spectrum on its screen formed by light coming through a near by window ? how this can happen ?

Hello all, the double split experiment, Am I correct that the test showed a lighter and a darker area of splitting of light?. What color light was used for the double slit experiment? Did you know that the double slit experiment can be done with your eyes and no other apparatus? Floaters, after several eye observation's and focal tests, in search of the photon's habit's , trying to discover new things, I came across to what you refer to as floaters of the eye. I have looked at eye worms, and this is not the same thing as I have seen. Do you have an explanation of what a floater actually is? I do know that myodesopsia are deposits…

How does the experience of time differ for observers moving at different velocities (that approaching c)

Meaning of KE=1/2m v^2? Hi. Lay person. I was wondering about a physical meaning to the speed-energy relation. I started from the equivalence between gravity and inertial acceleration. So I hypothesize that there is the same underlying phenomenon at work; given that matter-energy warps space and that warping is gravity, I would speculate that maybe a change in velocity also entails a warping of space. In particular I thought that if a change in velocity were associated to a warping of space in two dimensions (ie. orthogonal to the direction of the force) it would explain the quadratic relation between speed and the energy required to achieve it. This (very…

is there any relation ship b/w heat and velocity ?

Greetings everyone! I have a seemingly simple question that has been bugging me for a few days. Obviously, the Diet Coke and Mentos reaction has become quite popular on YouTube, as well as in classrooms. Usually the demonstration accompanies a discussion about the nucleation points on the Mentos that cause the CO2 in the soda to be rapidly released. In order for teachers to save money when repeatedly doing this demo, would it be possible to create artificial Mentos? By this I mean make an object (not sure if any shape would work) that had the same microscopic cavities as the candies, but was made out of a material that didn't wear down when exposed to moisture (making i…

The sun shines through the window and casts a shadow of a black pipe vertically onto the ground. The resulting shadow has different colors on different sides. Relative to the sun on the left side, the edge is orange-ish in color, and the right edge is blue-ish in color. At certain places, the edges have no orange-ish nor blue-ish colorations, particularly the part of the shadow closer to me. Furthermore, at different angles of shadow cast from the sun, the colored edges changes in sharpness, going from blurry to a sharp "clean" that seems even brighter than the actual, adjacent light on the ground. I might have an idea why the edges change in sharpness, but I am …

In this formula: ============================================= The total power radiated by a ground dipole is where f is the frequency I is the RMS current in the loop L is the length of the transmission line c is the speed of light h is the height above ground of the ionosphere D layer σ is the ground conductivity ============================================ The smaller the factor σ ---> the larger the power. ------> Does it mean reducing conductivity (or increasing resistivity) increases power ? Is that correct ? [ From http://en.wikipedia.org/wiki/Ground_antenna ]

There must be Many Thousands of Spent Highly Radioactive Nuclear fuel rods Buried or stored Somewhere . What if they could be used to produce Literally Free Electricity. They I Believe remain radioactive for many many years,so if this energy could be used instead of thrown away that can only be a good thing. The Point REVERSE VALVE TECHNOLOGY Valves are virtually Obsolete now but the technology was sound. Valves by nature give off Radiation as a matter of course, If a radioactive source was emmited towards a valve would it not force the valve to produce electricity. Obviously i am not talking about the standard household valve so constantly found in old radios a…

Ok so say you are a mass moving fate than the speed of light (ignore the fact that your mass would become greater than infinity) and you are moving away from the earth and the moon and you are watching the two spin backwards would you really be able to see the two spin or would you block your own light in the past relative to the light

So I've been reading up a bit on Raleigh scattering and I'm a little confused. What is the primary method of Raleigh scattering? Is it that the EM waves pass through slightly different densities of air molecules, causing the more susceptible frequencies (blue light, in the case of visible light in our atmosphere) to refract and scatter? Or is it that light waves excite the air molecules, causing them to vibrate at a similar frequency to the wave, and give off energy similar to the scattered light? I'm sorry if I'm completely off base here-- I learned a basic overview of light scattering in college, but didn't go into much depth and I'm curious now. Also, as a side note-…

Is it true that there is an infinite number of colors but this doesn't mean that the human eye can distinguish an infinite number of colors? Just as there are infinitely many numbers between 380 and 740 - including all of the fractions, of course - so there are infinitely many wavelengths between 380 and 740 nanometers - the visible spectrum of light. That doesn't even count the different tints and shades obtained by mixing in white, black, etc. So, it can be argued that there is an infinite number of colors, if you look at it that way. http://www.pburch.net/dyeing/dyeblog/C128544578/E1447734446/

A kangaroo hoping from A to B is an unpractical way of doing things why do waves do this?

We have physical building blocks to all matter, these combine in particular ways to make something bigger, after we do this a few times we will have object on our scale of reality that posses a set of properties. These sets of properties and there relationships then account for everything that can be sensed (and in some exotic cases not), also scientifically these properties and particular relationships can be demonstrated; such as sending and receiving radio wave, but dont necessarily need to be understood; such as the creation of mass? we can measure them over some time scale, observe the behavior of the property and even use proven methods to modify them in a predictab…

Recently I have made two test to see how much hydrogen is made with hot and with cold water and I have seen that when you put an electrolyser into hot water, the quantity of hydrogen obtained and the speed of electrolysis is higher that when you do the same test in cold water. What is the main explanation to this?

can we produce heat by rubbing same poles of magnet like north and north ?

why do light passes through transparent material but not opaque even both are solids ?

How I can reverse the time of universe???

before some time when some renovation work was going on my house i noted that when carpenter was making the wooden bar plane and shiny by using his blade , every peel of wood was curled , can any body tell me why that was happened why they wasn't flat ?
