what is the fastest thing oh this planet? Its not the vel. of light.........................?

Question

its some thing that one of the greatest physicians discovered!!!!!!

Answer 1

You have to be more specific. For example the speed of a signal in a cable is 200 000 km/sec that is 2/3 speed of light.

It is man made.

The fastest vehicle I guess has to be Helios 2 a solar probe at 70 km/sec

Answer 2

Gravitational forces act instantaneously throughout the entire universe. While there is some lag time before light can reach a destination. It may be possible to go faster than light, but you can't go faster than gravity. You can only emit more force than gravity.

Note Luke: That is a good read, thanks! And I think they are right. It makes sense. Something is throwing me off though:
Because light is made up of a tangible, physical substance, it slows down (refraction, etc). Gravity is a non-substantial attraction between masses. So while light can slow down because of friction, Gravity doesn't change speeds (as far as I can tell, but who am I). Which means gravity is faster than light. If it's the same speed as light gravity would proceed past light when light slows down, but is this possible to observe (this would also make gravity the fastest thing on this planet, as per the original question)(note: I think it would cease to exist past the light because it is one the sources of the attraction thereby making the speed of light seem like the faster velocity since gravity can't exist between two objects beyond their distance)?
Also note the 20% margin of error. In school, that's a C+ (or B- if using the letter system)
It seems like the only way to know for sure is to know exactly when a sun will appear in a vacuum, and race the light and gravity to the nearest solar system.

Definately a good read though, and I'm looking forward to reading the published article! Thanks again.

Answer 3

Quantum tunneling occurs at superluminal velocities (faster than light speeds) but no information is transmitted.

Quantum means very small (shorter than the planck length or smaller than 10 ^ -33cm or billions of billions of billionths of a millimeter) and tunneling is what happens when an electrion of other particle travels through an "impenitrable" barrier and turns up all of a sudden where it shouldn't, as if by 'magic'.

Also I recall thet "entangled" electrons' corresponsive behaviour is instantanious (faster than light) but I know less about that than tunneling, but again I believe Einsteins postulate that INFORMATION cannot be superluminal has not been falsified or shown to be false.

btw Master C (poster above me) the speed of gravity is the same as lightspeed, or so we think. Newton thought it instantaneous, but Einstein thought is was the same as c (lightspeed). Heres a link to recent experimental research pointing to lightspeed for gravity:

Although the results have been disputed, they are in line with relativity's predictions.

Answer 4

Well actually you are wrong. Since light is on the planet and according to the theory of relativity nothing is faster than the speed of light, light is indeed the faster thing on the planet.

Also electrical impulses like those in the mind as previously mentioned do travel at the speed of light.

Answer 5

No. you need to seem up the hypothetical tachyon debris yet there is 0 info in any respect that they exist. you assert its a super universe and it hasn't all been got here upon yet - this is real yet you need to bear in strategies that physics is in comparison to zoology the place you may seem in to a deep woodland and discover some unusual animal - if we comprehend a regulation of physics - and a super style of of them we comprehend particularly nicely - then they ought to hold everywhere. right here and on the different end of the universe. Einstein confirmed that easy become a cosmic velocity shrink together with his particular theory of relativity. To develop up an merchandise with mass as much as the cost of light might take a limiteless volume of potential - and that would not exist. Black holes would suck in easy as you assert, yet that would not propose that the sunshine ameliorations its velocity in any respect. the cost of light is variable - yet no longer interior the traditional vacuum of area, we've slowed it right down to three metres a 2d in unique aspects suggested as 'bose-einstein condensates' that are a diverse sort of rely from solids, beverages, gases or plasma. So no, no longer something can pass swifter straight away. nevertheless there is procedures around it. You point out wormholes - nicely in case you enter a wormhole and come out yet another one a million miles away one 2d later, then you definately've relatively travelled swifter than easy, good? bear in strategies huge universe - yet one set of actual rules that runs the tutor.

Answer 6

Well....Since it was one of our "greatest physicians" let me take a guess. Is it a person running out of a doctors office when the doctor says "bend over" and you hear the SNAP of the rubber gloves???

I'd say also possibly the speed of a woman running away when the doctor inserts that COLD cervix spreader thing into you except your trapped in those stirrups and can't run.

Answer 7

Bad news.

Since it is well known that nothing travels faster than bad news, research was done and a prototype drive system created. However, spaceships powered with bad news were soon found to be so profoundly unwelcome whenever they arrived anywhere that it really was not worth the trip.

[Edit]: John H.

Shadows cannot move faster than light. A shadow moves as fast as light will allow it to retreat, meaning it can move *at* the speed of light, but not faster than it.

Answer 8

Actually what I've seen is that is interference patterns that can appear on window screens and the like. Since it is only a pattern it is not dependent on light and therefore is faster

Answer 9

Darkness is the fastest thing. It takes ZERO units of time to spread.

Answer 10

A shadow can travel many times the speed of light. Call it a "thing" if you like.

However, since a shadow is defined as the absence of light, it is usually not considered a "thing".

And generally, "speed of light" is appropriate. "Velocity" is an unecessary adjective since we are discussing magnitudes.

[Edit]: Shadows can in fact seem to travel faster than light. Wag your finger in front of a lamp. On the wall on which the shadow is projected, your finger appears to move at D/d times the speed it actually moved (where D is distance of finger to wall, d is distance from lamp to finger), thus the shadow, which covered D instead of d at the same time, appears to move at D/d times the speed of light. Of course, this is an illusion, a shadow is neither energy nor matter and merely "appears" to travel faster.
