Who's Ready To Tax The Grey Matter?

Whenever we talk about aliens etc the limiting factor is always c. The usual suspects never accept that c is the speed limit and cite future invention etc. Anyway here is another very good explanation of why c is the limit. Enjoy:

Far too highbrow for me.

That's because the usual suspects enjoy swapping thoughts, ideas, information and theories.

The science and maths doubtless hold true here and now but much fun is to be gained from considering the 'what ifs?'

It's harmless, and doesn't need a fun-sponge finger-wagging and correcting our wrong-think.

I never needed convincing but I welcome new ways of explaining things that gives you a real light bulb moment. The use of pythagoras is inspired, the genius mathematician himself would have been delighted that his theorem was used to explain something that at the time he probably had no inkling of.

The possibility that we might discover alternative methods of travel by utilising for example wormholes or gravatational waves, has been suggested here, but I don't think I've ever seen anyone claim that we will at some time in the future be capable of exceeding the speed of light.   Grannies and eggs spring to mind with your post, TTT.

In the Stargate universe they use stable wormholes to travel from planet to planet.

You go through the gate and come out of another one at your destination.

All the aliens are humanoid and speak English.

Stargate Atlantis is set on Atlantis, in the Pegasus Galaxy.

come off it Naomi, you and others say that we can't say c will never be exceeded because we don't know what the future holds. We do know.

[jackthehat]

See?

Fun-sponge....

I think I've posted this elsewhere.

We don't know what the future holds, TTT.  Only you know that - apparently.

13:55 there you go I knew you wouldn't let me down Naomi!

[naomi24]

There you go.  You knew that too!  Amazing!

I don't think anyone here bothers to check out the links. Much more fun bickering.

I have  orbiting the fringes of my acquaintances ( my ex's nephew) a nuclear/ particle physicist( never did ascertain which) he works at CERN,  seems to have  every expectation that while we may not travel those vast distances it may be possible to communicate  I think it involved wormholes, and string theory.  I just kept providing beer and snacks  while trying to keep up.  

I would also like to add that while he is phenomenally intelligent he never puts any one down, or is in any way patronising he is a genuinely lovely person who obviously scores high on emotional intelligence as well as the traditional measures. Just saying....

[douglas9401]

As I recall the main problems with utilising String Theory for communication were keeping it taut and stopping the cans rusting.

Floatheadphysics is a good channel to follow.

Reeves(aka 'Squeeze') thinks that grey matter is worth hitting hard when it comes taxing IP and creativity - for those who decide to remain on these shores. It well maybe that she's creating an economic 'backflow' for those immigrant boats with the number of entrpreneurs and creatives now wanting to escape these shores.... Dennis Healey, your dream is coming true!

[douglas9401]

After one viewing, OG, I agree.

We believe the expansion of space is greater than the speed of light in a vacuum, so there is no reason to think that it can't be possible to apparently move faster than light while actually still complying with our theories on the light speed limit. We've just not stumbled across a practical solution yet. Maybe we wont: but maybe...
