What's the most significant advance made in physics in the last 10 years?

The confirmation (March 2013) of the existence of the Higgs Boson (Higgs mechanism) the prediction for which Peter Higgs and Francois Englert won the 2013 Nobel Prize for Physics.Actually the advance may be the completing and bringing to operational status the

How do compasses work?

Compasses work by aligning their needles in the direction of the present magnetic field. In other words, the needles are tiny magnets. For a typical needle compass(

What timeline would you predict for major developments in Quantum physics over the next 100 years?

As it is known to physicists,quantum mechanics or quantum physics is the general theory and the classical physics is its limit as h-----> o, where h is Plank constant with a value =6.63X10^-34 Joule .sec..Nowdays physics on the level  of understandind

Will humans ever be able to find out what is on the other side of a black hole/singularity?

There isn't another side of a black hole. A black hole is a place where gravity is so strong that all matter is compressed to the smallest size possible - probably something called the ‘Planck Length'. That's it! In real black holes there aren't other sides, or gateways - only an unimaginably

Do mobile phone radiations affect babies?

As far as I can tell, there is no evidence of method of harm; microwave radiation from phones is not ionizing.I'd recommend looking into studies and make sure those studies actually use the scientific method, not just the buzzword of

What is the use of the battery in the photoelectric cell? And can the cell work without the battery?

The battery is used for storage of energy to provide electricity in case of darkness. So the cell can work without battery, but only in light.

What would happen if you put your cell phone in the microwave?

My son and I have tried calling a mobile phone (as we call them over here) whilst it was in his microwave. It rang so the reception was not too bad.The point is that the Faraday cage that the microwave oven forms is designed for

What is the proof that mass is having an effect on space (and not space having an effect on mass)?

If we accept the general relativity view, spacetime does have an effect on the motion of the mass (or energy).  Mass tells spacetime how to curve.  The curvature of spacetime tells mass how to move.  There is no "limit" to the extent of either

How to pass a physics exam

Start studying early.You will not be able to grasp the concept of physics the night before the exam.Study daily.Listen to the classes carefully and clear your doubts.Seek help of teachers or friends.Read your book once and note the important points.Write formulas in a rough book.Read it again and again.Learn equations and definitions by

What programming languages do physicists use?

The other two answers mention FORTRAN. I suspect this is what used to be taught, because it certainly isn't covered now.I used C++ and was taught by a guy who wrote C++ programs for managing data at CERN.Later I used Python, with which the class completed a projects for handling

What kind of waves do phones transmit and is it harmful?

Yes mobile wave is harm becauseRadio waves from mobile phones harm cells and damage DNA, according to a four-year European study.The Reflex study, conducted by 12 groups across Europe, found that cells exposed to high-frequency radio waves from mobiles had significantly

Are consciousness and energy the same thing?

Energy has a specific meaning that is well understood by physicists. And for people outside of physics, it's very difficult to understand just how much we know about the basic forces making up our world.All we need to account for everything we see in our everyday lives are a handful of particles - electrons, protons, and

What are some mind blowing science hacks that most people don't know about?

If you want to see the single slit diffraction pattern, use a Faber Castell Connector Pens.Put them into the following assembly. And move them towards a light source (CFL/LED) bulb, with your eyes on the interconnecting body area. Press it inwards to decrease the slit width, and voila Experience Physics!

What gives a singularity point its energy?

The theory of everything in physics does not account for the presence of consciousness in the universe and it does not explain the origin of energy. Following modified theory of big bang explains these two aspects and therefore can be called the theory of everything.In the beginning there was unified field of consciousness (Spirit)

What is the best way to learn physics?

Look at this formula F=ma, even if you're a layman you would know that F stands for force, m for mass and a for acceleration. That's the basic but what does it really means, when you read or even think a little further you would know that it means Force applied on any object with mass

Why do we use a triangular wave generator in a cell phone jammer?

Cell phone operates normally and can identify itself i.e. send receive data and calls when both its up-link and down-link channels are 'working' - i.e. through both the channels, connectivity to base station exists and can be sustained. Cell phone jammer tries (and almost always succeeds without giving a hint) to block one

Where did Earth get its gravity from?

From its mass. The earth weighs 5.98x10^24 Kg, IIRC, and has a radius[1] of 6378495m. so gravity = [math] 5.98e24 * 6.67408e-11 / 6378495^2 = 9.81 m/s^2[/math][1]/. Yes I know! oblate spheroid... but what the hell!

What's the property of light that doesn't change when it travels from one medium to another medium?

Hmmm... I might get balled out for this, but.....The 4 ‘properties' of ‘light' (photons), are . . . .Velocity, Amplitude, Frequency and Wavelength . SO....‘Velocity' can/does change, through different ‘mediums', whichdepends on the ‘mediums' refractive index.‘Amplitude' can change, relative to attenuation due to the degreeof transparency of the ‘medium'.During ‘transmission'

Do photons have mass?

There are some unanswered questions or complex concepts in modern physics. In general, these issues are divided into two categories:The questions that modern physics does not have answers for, and the physicists believe that it is due to the inability of theories.The reason of these unanswered problem is point

What time is taken by light to reach the Moon's surface from the Sun?

There is not much of a difference between the solar light reaching earth and reaching the moon. The only difference is that during the New Moon the solar light takes 20 seconds less while during the Full Moon it takes

How many times would I go around the Earth in a year at the speed of light?

7.5 times a second, times 60 seconds a minute, times 60 minutes an hour, times 24 hours a day, times 365,25 days a year.236 682 000 times.

Would a spaceship traveling the speed of light look like a beam of light?

Nothing with mass can ever travel at the speed of light but a spaceship can travel very close to it 0.999c is perfectly possible. At 0.999c, no it will not look like a beam, it will look like a flattened spaceship. Its width and height will be normal but its length will be shrinked over 22 times.

How does sound travel through water?

The same way sound travels through air, by compression waves. The differences lie in how fast the sound travels and how quickly it diminishes, which are based on the density of the medium. This is also why sound doesn't travel in space. There is no medium to transmit for the compression waves to travel through.

How viable is the idea of designing a spaceship for global faster-than-light travel by manipulating local space around the spaceship to make distance traveled locally shorter?

This is Alcubierre's idea, and it doesn't work, because there is an energy condition on matter which cannot be realistically violated which guarantees that you can't outrun light locally. It is the same condition that makes it that black holes

What is emissivity?

Emissivity is the

What is faster, the speed of light or the speed of darkness?

The speed of dark was proven to be greater than the speed of light by the troll mathematical physicist Big Al Onestone.His Theory of Special, General and Totally Indiscriminate Relativism states that if the speed of light were 600mph, the speed of dark would be at least 601mph. Otherwise, it wouldn't be able to get

Why would it be impossible to travel at the speed of light through a vacuum, I mean, it's not like there is any friction stopping the craft, so why would infinite fuel be needed?

Because the answer is.....drum roll please... the universe is way it is...Thats the answer. Friction isnt the cause of your blockade to speed of light. It is the universe itself. Or i should say space-time fabric itself.Our existence is defined according to our interaction with space ans time. At rest we dont travel through space but we travel

If, at the speed of light time stops, how do photons have motion that is measurable?

Different frames of reference.Time stops in the frame of reference of a photon - a massless particle travelling at the speed of light (as seen by other massive observers.)For observers that have mass, the photon is travelling at the speed of light - although the observervers will experience that photon to have different wavelengths (or energy).

What is the maximum speed we can travel in vacuum?

Easy: 299,792,458m/s - the speed of light.In a vacuum, the only thing stopping you from going faster is the amount of fuel you can carry! Of course - when you get close to the speed of light, relativity kicks in - and you cant

How long would it take to travel to the super earth Kepler-452b?

Using current technology of rockets and spacecrafts the trip is impossible, no matter what is on the drawing boards.  The trip itself is not impossible for humans; just using current space technology makes it that way.  The only other thing that makes it impossible, is physics silly solution to real teleportation; the Star Trek methodology of scanning/decoding

Can this come close to the speed of light?

If that is what you wish to do, why are you stacking up 1 million escalators ?After all, the topmost escalator moves at 10^9 Km/h and the machine that is running this escalator will supply the whole power i.e. F*10^9 Watts. So first of all, there is no use of stacking up the

Will a vacuum affect how the speed of light travels?

Light can change speed, even in a vacuum, a new paper reports. The discovery could change the way we think about one of the constants of the universe.

If photons are supposed to be the emission of light, do 'virtual' photons emit light?

I've been asked to answer this question, but I can't because I don't believe in virtual photons. I don't see how anyone in their right mind can believe in a reality that includes

Does sound reflect like light?

Yes it does, and it's a phenomenon you have experienced many times: we call a reflected sound an echo.As with light, for a surface to reflect sound it needs to be smooth enough in relation to the wavelength of the sound which in practice means the

Why does light bend around heavy objects?

GRAVITY!Every thing attracts other things in universe. Even it is mass or energy. Light is made up of subatomic particles called photons. Check my post for reason of your answer.Post by Moksha Kumar on The mysterious universe

Is it possible that light also bends space time fabric like gravity?

This question itself is questionable. Space-Time Continuum is being debated since the era of Einstein & Poincare and even presently it is an enigma. In May, this year, the fifth conference on the Nature and Ontology of STC was organized in Albena, BULGARIA and the theme was Nature of STC - real or imaginary?

What is the fundamental reason of the speed of light being constant in all frames of reference?

The most simple answer to this might not be very satisfactory, but as I see it this is one of these question with the answer
