Discussion Overview

The discussion revolves around the feasibility and implications of creating a device capable of perceiving the entire spectrum of light. Participants explore the technological possibilities, potential advantages, and limitations of such a device.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants question the feasibility of a single device that can see the entire spectrum of light, suggesting instead that multiple devices could be used in conjunction to achieve a similar effect.
  • One participant raises concerns about the trade-offs between resolution and bandwidth, indicating that a comprehensive view may require sacrificing one for the other.
  • A participant introduces a theoretical limit related to the energy of the universe, proposing a relationship involving frequency and energy, although the specifics of this relationship are questioned by another participant.
  • There is a clarification regarding the notation used in the discussion, with one participant expressing confusion over the mathematical representation of frequency in relation to energy.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of a single device versus multiple devices, and there is no consensus on the implications of the proposed theoretical limits. The discussion remains unresolved regarding the practicality and design of such a device.

Contextual Notes

Participants have not fully defined the parameters of "seeing all" in terms of the spectrum, and there are unresolved mathematical expressions related to energy and frequency.

first thing, do you think such a device can be technologically feasible?
do you think we need it?

i think if we can build such a device why not?! i think the advantages of it are more than the disadvantages.

See all what?

All the spectrum of the light.
 
You can't build a single device that sees the entire spectrum, but you can build a bunch of separate devices that see parts of it and link them together. Same effect.
 
At some point you would have to sacrifice resolution for bandwidth for the final "viewing"; or you would only be able to view sections of the spectrum at any time.

As an upper limit, I suggest the frequency √ = E/h; where E is the total energy of the universe.

We will need an infinitely long antenna for the low end.
:wink:
 
square root of what equals E/h?

I just thought the radic looks more like the nu that I know and love.
I meant frequency = E/h
