They are so small they can go straight through. Heres why:
Atoms are spinning so fast that they look solid. Picture a fan, the blades - when still -have large spaces between them. Your hand could easily pass through. But if the blades were spinning, your hand would be cut off.
This is similar with atoms, where the electrons are spinning so fast that it feels solid. Neutrinos are so small that they can pass through these gaps, when our hands are to big to fit through and matter appears to be solid.
Thus at the macro level it is solid, but at a subatomic level you are walking through air.
What else can I help you with?
When light hits the earth's surface does it continue through?
Nope. Light particles (photons)are nowhere near energetic enough to do that. On the other hand, tiny super-high-energy particles called, "Neutrinos" from outside the Earth are right now passing through you, me, and the entire Earth. There are not many materials dense enough to stop Neutrinos!
How many neutrinos from supernova SN 1987A were detected on Earth?
There are somewhere around 65 billion neutrinos per second passing through every square centimeter perpendicular to the Sun. By far the majority of those also come out the other side... baryonic matter is essentially transparent to neutrinos.
Do solar neutrino carry energy?
Yes, solar neutrinos do carry energy. Neutrinos are extremely light, neutral particles that are produced in nuclear reactions within the Sun's core. The energy carried by solar neutrinos can affect processes such as nuclear reactions on Earth.
Is radiation stopped by anything?
It depends on the type of radiation. Alpha can be stopped with a few inches of air, or even a sheet of paper. Beta can be stopped with a sheet of metal. Gamma and neutron takes lead and/or concrete, sometimes several feet. Neutrinos can hardly be stopped by anything - they travel through the Earth with ease.
How do measurements of neutrinos from the sun pose a problem for modern astronomy?
At present, no problems. 15 years ago, scientists had no explanation for the small number of solar neutrinos detected at our Earth. Either we didn't understand neutrino formation in our Sun, our detectors were wrong, or neutrinos had the capacity to decay. The latter seemed to be the least likely possibility, so scientists argued for many years which of the first two was correct. In 1998 it was discovered that neutrinos do, indeed, decay into other neutrinos. The reason we weren't seeing as many neutrinos as we expected was because the ones we were expecting to see had decayed into other types. So the solar neutrino problem is no longer a problem.
Are neutrinos dangerous to the earth?
Neutrinos are not harmful to Earth or its inhabitants. They interact extremely weakly with matter and pass through our planet as well as us without causing any harm. Millions of neutrinos pass through us every second without us even noticing.
Can neutrinoes pass through all matirials in the Earth?
Neutrinos can pass through most materials in the Earth, including rock and metal, with almost no interactions due to their extremely weak interaction with matter. However, some materials, like lead or water, may absorb or scatter neutrinos to a small extent. Overall, neutrinos are able to travel through vast amounts of matter without being significantly absorbed or deflected.
What about the neutrino coming from space?
Neutrinos are high energy particles. Earth is bombarded with more than million neutrinos every day that pass right through the earth, and everything on it. So they are very hard to detect, but special techniques have been developed for this too.
What are the particles that enter Earth's atmosphere?
THIS IS NOT SPELLED WRONG Neutrinos.
What Are Particles That Enter Earth's Atmosphere Called?
THIS IS NOT SPELLED WRONG Neutrinos.
When light hits the earth's surface does it continue through?
Nope. Light particles (photons)are nowhere near energetic enough to do that. On the other hand, tiny super-high-energy particles called, "Neutrinos" from outside the Earth are right now passing through you, me, and the entire Earth. There are not many materials dense enough to stop Neutrinos!
Can neutrinos change into other types of neutrinos?
Yes; the scienific terminology for this phenomenon is "neutrino oscillation". Neutrinos exist in three different flavours - electron, muon and tao neutrinos, listed in order of increasing mass (each also has an antiparticle). Although it is not know why this is the case, it was originally discovered that neutrinos oscillate when examining the neutrinos emitted by the sun; although primarily electron neutrinos are emitted as a result of the fusion process within the sun, the quantities of the different flavours of neutrinos detected on Earth from the sun are in roughly equal proportions.
How many days would it take to travel round the earth without stopping?
16,000 days if you were an idiot
How many neutrinos from supernova SN 1987A were detected on Earth?
There are somewhere around 65 billion neutrinos per second passing through every square centimeter perpendicular to the Sun. By far the majority of those also come out the other side... baryonic matter is essentially transparent to neutrinos.
Is it possible that neutrino showers will be the cause of earth's end?
I very much doubt it.We are bombarded by neutrinos from the Sun every second.It has been estimated that more than 50 trillion neutrinos pass through the human body every second. - that's one good shower.
How small is a neutrino?
Pretty small. Although the exact mass of these particles (there are three "flavors" of neutrinos) is unknown, the maximum possible mass of the heaviest possible neutrino is about a millionth of the mass of an electron.
Do solar neutrino carry energy?
Yes, solar neutrinos do carry energy. Neutrinos are extremely light, neutral particles that are produced in nuclear reactions within the Sun's core. The energy carried by solar neutrinos can affect processes such as nuclear reactions on Earth.
