It is simply incorrect to say if it can be slowed then it can be sped up. That has no scientific basis in reality. You can always slow something down by creating an obstacle for it which is what happens when light is slowed down. However, light has no mass hence why light can approach the speed of light. Other objects can't approach or exceed that speed because they have mass.

Also Brett confuses special and general relatively. In special relatively, nothing can travel faster than the speed of light. Special relativity is with respect to local laws of physics. In the case of a galaxy far away from us, it can be perceived as moving faster than the speed of light because it is far away and because space itself is expanding. The galaxy itself is not traveling faster than light but because the galaxy is far away and space itself is expanding, our perception is such that it appears to travel faster than light which is allowed under general relativity since that is a global effect with global meaning the medium through which something is traveling is creating the appearance of FTL travel.

This has zero implications with respect to light heading towards us as light heading towards us gets less and less far away and thus is a local effect and thus due to special relativity can't exceed the speed of light.


I'm sorry, but I had to chuckle at that......

That's not what the Big Bang would say.

That is exactly what the big bang says. Again the speed of light is local and relates to motion relative to the space-time. An object in motion cannot exceed the speed of light relative to space-time.

What happened in the big bang is as Modo states. The matter in the early universe did not travel faster than the speed of light relative to space-time. Instead, space-time itself expanded. That expansion is allowed to proceed faster than the speed of light because it is not relative to space-time but is space-time.

Put another way. Objects exist within this thing we call space-time. Those objects cannot travel faster than the speed of light per special relativity. However, space-time itself is not confined to this rule because space-time is not an object within space-time but is the actual global medium through which objects travel.

So what happened in the early big bang is that space-time itself expanded faster than the speed of light but the actual objects within space time did not. It is just that because those objects existed within space-time and space-time itself was expanding, it made it the objects appear to travel faster than light when in fact they did not.

It does sound weird but it takes like 220k of electron volts to get an electron to 90% the speed of light. However, it takes over 11 million electron volts to get it to 99.9% the speed of light. So the final 9.9% takes over 10.7 million electron volts compared to the first 90% only needing 220k. And as you add energy the electron gets heavier so it will never reach 100%

So, light can never achieve the speed of light? LOL.

Of course it can because it has no mass. That was the point. May be my use of the term approach but I was using it to say it can get to the speed of light because it has no mass. Other objects can't approach or get to that speed because they have mass.

Dude, I am just messin' with you, because of this:

However, light has no mass hence why light can approach the speed of light.

Come on, that's funny stuff right there................

Right and I agree the sentence sounded weird but just wanted to make sure what I was saying was understood.

You guys know brett neither understands, nor cares, what you say about the speed of light.

He will continue to broadly believe that the speed of light is not constant.

God messed with the speed of light when he created the Universe.

Speed of light is not a valid way to show the Universe is older than 6-10k years.

You might as well explain Thermodynamics to a toddler.

Toddlers don't subscribe to the laws of thermodynamics.

It's much worse than that, a toddler will listen for 10 seconds then stick his hand in his mouth and walk away, wasting no more of your time. Brett on the other hand is able to get these guys to continue wasting their time explaining things to him that may as well be instructions on how to build a light sabre. He is 100% positive everything they are saying is pure fiction.

I'm enjoying this thread, other people explaining science to Brett is one of life's simple pleasures.

Brett is positing about the fluidity of light speed.... On machines that depend on a constant .68 light speed travel over cat 5 medium and .87 light speed on coax medium to synchronize and transmit meaningful data.

Pure witchcraft. Perhaps the internet is not a thing, and god just zaps the words machine to machine.

Brett may not learn anything in here, but the rest of us can.

Yes it is the distinction in general relativity vs special relativity or global vs localized speed of light.

An Alcubierre Warp drive for example works by contracting space in front of it and expanding space behind it thus achieving apparent faster than light travel. The spacecraft is not actually exceeding the speed of light but rather it is affecting the space around it in such a way to draw the space in front of it closer to it as it travels and the space behind it away from it. So almost like it is playing tug of war with space itself.

Sometimes you say shit that blows my mind... this is one of those times.
The idea we will one day travel outside the solar system is fascinating. It’s a shame I will not be alive to see anything past possibly Mars.

**** that, I am getting cryogenically frozen so they can revive me when they figure out how to transfer consciousness as well as space travel.

The Alcubierre drive may not ever be possible anyway.....at this point there is no known way to create a warp bubble, no way to get out of it once you are in it, and if you could get out of it, it may destroy the destination you are trying to reach.

In short, probably not going to ever happen.

Sounds like a bad case of gas.
