Speed of light divided by speed of sound? How many machs would equal the speed of light?
I'm curious because I just read the US military has a remote plane that flew at mach 20,,and it could go to LA from NY in 12 minutes.Also traveling the speed of light...

Simply....
The speed of light?).
The speed of sound at STP is around 750mph(?).
Using 3 x 10^8 m/sec as the speed of light and 340 m/sec as the speed of sound, light travels a calc handy, so I'll wing it here.

Astronomers measure something that is called "redshift" with symbol "z".
Z=1.4 means speed of light. All close galaxies have "z" lower than 1.4 it means they moving away from us at speeds lower than speed of light.
But all far galaxies have redshift far...

No energy their speed....
Space itself however, can expand or contract as fast as it "wants" .
If nothing than why we see galaxies with so big than speed of light.
Einstein said "nothing can go faster than speed of light".

If there's a speed of sound and a speed of light is there a speed of smell?

How can the universe expand faster than the speed of light? I thought nothing can break the speed of light.

But SR applies only locally in GR expands faster than light (it expands at a rate, not a "speed"), space is not a "massive" object.
Nothing can exceed the speed of light in special relativity.

The speed of light is the speed with which light travels.
Of by definition.

I'm having trouble understanding what the speed limit means because as far as i understand it works like this: as you speed up time slows down on board. Thus if you measure speed by distance moved / time than doesnt this allow you to override the speed...

As you accelerate close to the speed of light, the distance to your destination shrinks at light speed ....

I have debated the Speed of Light with many scientists and still remain convinced that the scientific community has made a grave error in either calculating the speed of light or determining that it is the absolute fastest speed in the universe.

There's something that people don't explain when traveling at the speed of light.
Speed of Light = 180,000 miles/second.
Now imagine your traveling light speed in a straight line.
