Some of the particles coming from the sun to earth are faster then light, are they travelling back in time?

Question

are these particles from another physics?

Answer 1

Light != time

Answer 2

No, it simply means that in a particular medium they travel faster than light. I assume you are speaking of particles created in the center of the sun reaching the earth before the light created by the same event does. I've never heard of this before but it seems possible since it takes light quite a long time to reach the surface from the core.
Looking at particles as travelling backwards in time is a way of looking at an anit particle and its partical equivalent as the same particle and has nothing to do with velocities.

Answer 3

None of the particles coming from the sun are travelling faster than the speed of light. Where did you hear that?

Answer 4

to the best of my knowledge there arent any particles from the sun that reach the earth before light does, however in certain mediums some particles can travel faster than light, this causes what they call cerenkov radiation.

Answer 5

I don't believe any particles from the sun are traveling faster than the speed of light. The solar wind only travels at 400km/s and 750km/s (these may be a little off) depending on what region you are talking about (equatorial or polar). This is by far much slower than the speed of light 300000km/s. Neutrinos from the sun might travel near the speed of light but not at it and not faster.

Answer 6

So far, tachyons (particles moving faster than the speed of light) are merely theoretical. Scientists are considering the possibility of their existence, but there's no solid evidence yet. According to Einstein, nothing can move at superluminal speeds. So as of now, science does not know of any particles that do travel faster than the speed of light.

Answer 7

At this 2d, we are receding from the furthest galaxies some distance previous the shrink of observability, swifter than the cost of sunshine. interior the early universe, area prolonged many hundreds of circumstances swifter than easy whilst it went by way of an extremely short inflationary section. area in our accelerating observable universe is destined additionally boost swifter than easy, such that each and all and sundry different galaxies, different than those gravitationally certain interior the Milky way / Andromeda gadget, will ultimately disappear outdoors the shrink of observability, in simple terms as those furthest galaxies did because of the fact of inflation. Einstein's particular relativity facilitates area to boost swifter than easy, yet no longer for a physique with mass to shuttle by way of area swifter than the cost of sunshine in a vacuum.

Answer 8

What evidence is there for Tachyons coming from the sun? This is the first I have heard about it !

Answer 9

NO.

They are from science fiction novels.
