Why not talk about... portals?

(Not related to Valve's Portal).

I'm not a physicist, and I have a lot to learn yet. But, isn't this "wormhole" idea a little too much absurd?

Why not think in wireless communication instead? What if matter could be converted to specific waves and then transferred perfectly to any "receiver" (And then converted back)? It's a concept much different from "wormholes". It would work much like radio. Is this idea widespread? (I have no idea), or everyone always think in "wormholes"? (I guess it would not work exactly like in the Valve's game, considering the "conversion time". So, it would end up being more like a "teleport" instead of a portal.)

That's essentially how the transporters in Star Trek work. Their biggest shortcoming is being limited to the speed of light, so they would be no good for long distance travel.

You're right, it reminds a lot Star Trek. How long is that "long distance"? If it was from a country to another, I guess it would be good enough already :).

and physicists such as Heisenberg prooved that transmitting a person via radiowaves would be impossible because of the uncertaincy principle.

And that is why Star Trek's transporters use a Heisenberg Compensator

Haha.. I'm reading about those transporters to get to the "Heisenberg Compensator" part.

Converting matter into energy, transmitting it, and reconstructing the matter using that energy is something that will never be able to work for the following reasons.

• The first issue is the sheer amount of energy to convert. For instance, I weigh 68kg, so my conversion would result in E=mc^2 = 6.1e18 joules (6.1 quintillion). To give you a means of comparison, you could power the entire human race on planet earth for approximately 3.5 days if you were to use me as fuel.
• Conversion is never 100% efficient. Realistically, we could assume 98%? Well, how would you like 2% of your body missing after transport?
• You can't transmit 6.1e18 joules of energy over long distances, and even if you could, transmission through the air follows the inverse square rule, where the amount of energy left decreases exponentially over distance.

If you think of portals as intersections of 3D space through the 4th dimension, they make perfect sense. But who knows how to manipulate space in the 4th dimension, and how much power something like that would require?

Interesting Star Trek fact: Filming a landing sequence did not fit into their budget, so they had to invent "beaming" in order to make up for it.
