1. nothing is impossible....

my new theories on science..............

time travel is possible now! hurra

my next door neighbor is an alien from andromada galaxy, came previous day on earth!!

human dont need food anymore! hurra

human can modify genes to live an infinite life!! hurra

2.

and one serious question!!! can sound travel with speed of light if proper type of medium provided

NO!

Learn some science!

5. @metoer

thats logic brother: sound travels fastest in solids, and least in air...... so if scientists can go for Hardon Collider to create new matter than why can they not build something to make speed of sound equal to light or greater.

and provide me reason , be not my master by saying NO

No, if you knew any science, you would know that sound requires a medium of particles. And since no particle can travel as fast as the speed of light, no sound could propogate at such a speed.

An by the way, this is off topic for this discussion.

7. and one thing .................... if we know the speed of light, do we also know the speed of dark!

if we measure temperature it goes to infinite, but we cant measure COLDNESS below -273K, so there are always limits.

here my point is "what is the minimum speed in the universe", we know max, and it is really not maximum at all! and i think i am logically right.

can there be "Negative Speed"

8. THIS IS OFF TOPIC FOR THIS DISCUSSION

Start a thread somewhere else in the forum. Like in the appropriate place.

As Terry Pratchett said: "No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it."

if we measure temperature it goes to infinite
I doubt that is true.

here my point is "what is the minimum speed in the universe"
Zero. (But don't forget that all speed is relative).

, we know max, and it is really not maximum at all! and i think i am logically right.
You are just wrong.

can there be "Negative Speed"
There can certainly be negative velocity; it is speed in the opposite direction. (I assume you know the difference between speed and velocity?)

10. during world war II scientists feared that SOUND BARRIER , and now scientists of NUCLEAR age fear "LIGHT BARRIER"......

11. sigh...

A statement consisting of two false assertions must, necessarily, be false.

Unless you have some ... you know ... evidence? No? OK.

13. first come to Negative speed:::: i know speed, velocity and acceleration in detail..... there is negative acceleration.

suppose there are two alevators, one attached inside other, both moving in an stationary building. one is bigger which move downwards and one is small inside. the one which is inside is also moving, but upwards!. now suppose the cable of outer alevator is broken it comes downwith speed equal to gravity, ie weightless..but the inner alevator is still moving upward! what type of speed it has....! i think it is negative speed.

now come to Light Barrier: einstein says if you move with speed of light, your mass will increase! etc. so the fear factor like sound barrier.... please search about fear of pilots during WW II. thats enough.. this is light speed of which we fear, we have to travel faster than light to survive in this galaxy/universe.

i know the minimum speed is 0, but this is oversimplification......... as the minimum temperature is Absolute Zero (not equal to zero quantitatively) so there should be speed absolute zero, scientists should work on it, it will help them to understand better light speed...... (and one thing forget about relativity , discussing motion and speed ONLY here in this thread)

Clearly not.

Negative speed relative to what? Could you show us how you calculated this?

now come to Light Barrier: einstein says if you move with speed of light, your mass will increase! etc. so the fear factor
It has nothing to do with "fear"; it is a result of the physics that it would require infinite energy to reach c. Perhaps you copuld show the calculations that show this to be wrong?

like sound barrier.... please search about fear of pilots during WW II.
Or you could provide the evidence to support your claims instead of expecting others to find it for you.

(and one thing forget about relativity , discussing motion and speed ONLY here in this thread)
But motion and speed are relative and relativity is the most accurate theory we have for working with them so you cannot just ignore it (even if you don't understand it).

15. @ strange
actually i am an economist by degree..... but i am highly interested in science specially super science like astronomy, bio, chemistry. it helps me to find me some pleasure... i am scientist not by my profession but by my enthusiasm..... i may miss some things in detail, but all these ideas of mine are absolutely from my mind not copypasted form anywhere, or learnt them from any book......

so if you are an astronomer then clearly negate me with solid proofs or tell me that you are also an enterpreneur like me who take adventures and risks evryday.

16. and one thing added .understanding physics is my actually dream, but to the limit that gives me pleasure... not to the limit that complexes everything with calculations

There is no similarity between the so-called "sound barrier" and the speed of light limit. As early as the 19th century guns were able to fire bullets at greater than sound speeds. The tip of a bullwhip breaks the "sound barrier. So in WWII, scientists already knew that it was possible for objects to travel faster than sound. It was not something considered impossible according to physics.

The sound barrier was more a matter of aerodynamics. Propellers became less efficient as you approached the speed of sound and the there were effects on the fly-ability of aircraft. Breaking the sound barrier merely required the proper engineering to over come these problems.

The speed of light is totally different, it is something that is built right into the way the universe works. It is a fundamental property of the universe. Overcoming it would take more than just improved engineering, it would take re-writing the rules of the universe itself.

18. that seems more plausible....... can we overcome throug wormholes i means negative matter (correct me i am wrong.) and kindly tell me how much science has made progress in this regard?
