Is Anything Faster Than The Speed Of Light?

What do you think?

Some scientists say that “tachyons” might be able to do it..

The ever entertaining Veritasium examines the question, can anything travel faster than the speed of light.  People actually are in both camps, and it is almost impossible to discuss this debate without referencing the work of Einstein from earlier in the 20th century.  There are new models out now that would suggest yes, and in terms of our own space travel, we are far from getting close to this speed.

Let’s find out what possibilities they discuss in the video on page 2

    Expansion and gravity both are faster than light. Expansion after the Big Bang grew the universe to 2 3rds it size in seconds. As particles picked up mass it slowed
    Gravity propagates so given enough gravitational mass i.e. Black holes.
    Electromagnetic fields could be faster. Still needs to be proved. But that will lead to FTL if it is.

    That depends on if they use the old definition of the speed of light, (because it’s speed actually fluctuated) or on the new definition they made in the 70’s ( they were so confused as to why the speed of light could change in computer simulations) so since they couldn’t solve that problem they changed the whole definition of the speed of light and now it’s a constant… stupid scientists

    It’s the stuff between two quantum particles that make them react the same, its instantaneous regardless how far apart they are

    Because of light can escape a black hole xD its a sorta thing like that but not exactly I’ll see if I can find the vid and I’ll post it hear and yes the expansion of the universe should be faster than speed of light

    I would think the speed of light would be different depending on what kind of light (photons) ultraviolet probably difrent from infrared light

    If you were to shine a light moving at the speed of light technically special relativity would state that you could at least double it that would also fall into quantum mechanics of energy too

    Yes.. if the big bang happen.. then the expulsion of elements had to have lead any light. Light is only a measure of whatever light is. If a force is great enough why would there be a limit to speed when there isnt any other limits in space?

    I don’t know, I’ve considered that light should be a its own element without mass or physical attributes, its the only thing that exist without physical existence until coming upon matter, it would have a mass of 0 . . . . . . (random thinking) nothing can be faster as its own weight doesn’t inhibit its movement, so no nothing can be faster without damaging itself in some way

  9. Garrett Gentile said:

    They actually discovered certain particles that move faster then light.

    And its believed that gravity moves faster then light. Its a instantaneous affect. There for gravity must travel through space/time or travel faster then light. Either way its geting to a destination faster then light particles

    Because objects get heavier, shorter, and time slows down as they approach the speed of light (relativity). At the speed of light an object would be infinitely massive, have zero length, and time would stop moving. It would take an infinite force to get an object from just below the speed of light to the speed of light. That’s why it’s impossible.

    Not true light does have mass though minuscule in size it is made up of particles with a very small density light moves so fast because the particles that make it up are not attracted to one another which in a vacuum is what causes “drag”

  12. John Blanton said:

    Supplement “expulsion of atoms” with “expansion of space”. The theory is that space itself is what expanded. Pure energy was the fill of the “void” at this time. Subatomic particles formed after the bulk of the rapid expansion had taken place. No particles broke any law. The super force did not separate into the known 4 we have now until after rapid expansion had occured and things started to “cool”. The only part where violation becomes a possibility, according to the theory, is the at singularity. All laws break down at this point.

  13. John Blanton said:

    It’s a loophole. What would emit the light (while traveling, itslef) at the speed of light? Answer, an object with mass (e.g. a bulb). What does relativity tell us objects with mass can not do?; Travel at the speed of light…
    But no, relativity does not state that the speed of light would be doubled. Einstein’s theorized and calculated that the speed of light is constant, regardless of the velocity of the source of emittion.

  14. Ryan Herrington said:

    But laws and relativity are simply a perspective.. at certain junctures in space there are no laws, physics break down an things are truely unknown.. there is infinitely small as there is big.. and the same applies to speed. Things stand still as they forever increase in speed. Just because we judge light at a certain speed.. doesnt mean it doesnt move faster an has already proven to move slower.. this universe has many things that affect each other.. an i would assume light on its own may be the fastest thing in the universe on a constant level.. but with incredible energy something could out pace light.. we just have to figure how to break the light barrier.. which technically a worm hole could do just that.. but as far as an object it would be from a huge explosion from the likes of the big bang. An ever supernova a really super super nova could potentially produce the power to eject matter faster than light.. my theory anyways.

  15. Marcelo Hernandez said:

    Everything expelled during the big bang eventually slowed down on its own with or without being stopped by anything, light bounces and continues without being stopped it just constantly continues, so nothing could be faster as it never loses momentum

    If we were to travel faster than light, then would we not travel into complete darkness?
    At that point we would not be able to see what was in front of us, or what was on our peripherals, until we slowed down and the light “caught up” to us, ( unless wormholes are lighted by some other dimensional force).

    If we were to look back at the light we have passed up, what would we see?…a single point of light?..or a wall of light stretching horizontally and vertically?..to infinity in both directions?..or a single flat line of light stretching to infinity??
    One could imagine that we would be in a vast, dark “space”. In front of us, nothing, ( unless traveling through a lighted wormhole…wait, what??..other dimensional faster-than-light lighting sources??).
    Slowing down or stopping would bring “the light” we have accelerated away from rushing back upon us.
    Then what? Time dilation?
    So then travel the exact opposite direction at exactly the same faster-than-light rate for exactly the same duration and then stop…what then?..zeroed out time dilation?? Time travel solution?
