Discussion Overview

The discussion revolves around the question of whether there exists an element that cannot pass through light. Participants explore the implications of such an element, its potential applications, and the nature of light and materials. The conversation touches on concepts from physics and chemistry, but remains largely speculative and informal.

Discussion Character

  • Debate/contested
  • Exploratory
  • Conceptual clarification

Main Points Raised

  • One participant questions the clarity of the original question, stating that no material can be said to not pass through light.
  • Another participant argues that if such an element exists, it could have significant real-world applications, suggesting that physics should explore the impossible.
  • There are suggestions to clarify the types of light before discussing the hypothetical element.
  • Some participants express skepticism about the existence of such an element, with one stating that the inquiry is pointless.
  • A participant mentions that while paper does not pass through a laser beam, this does not imply the existence of an element that cannot pass through light.
  • There is a discussion about the properties of materials, with one participant suggesting that all solid and liquid elements reflect light, depending on the wavelength.
  • Another participant proposes the idea of an element that could deflect light or laser beams, prompting a discussion about mirrors and their classification.
  • One participant expresses interest in the burning process of paper when exposed to a high-powered laser beam, seeking a detailed explanation.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the existence of an element that cannot pass through light. Multiple competing views are presented, with some asserting that such an element cannot exist, while others speculate about its potential implications.

Contextual Notes

The discussion lacks clarity on the definitions of light and the properties of materials, leading to confusion. There are unresolved assumptions about the nature of light and its interaction with different elements.

Hi guys.

Just wondering.
What element that can't pass through light?

By the way I finished computer science so I don't know much about physics.

Thanks in advanced.
 
Science news on Phys.org
That question could certainly use some clarification; it makes no sense as written. There is no material substance that can't pass through light.
 
@danger

Thanks for your answer but I think there is.
It's just like saying Hey! Albert Einstein your theory is not possible.
Then time pass by Albert Einstein prove it, that it's possible.

As a physicist it's your duty to define and discover the impossible.
If you think there is none then prove it in mathematical equation.
If you think there is then again prove it in mathematical equation.

Again physics is not my specialty so I don't have enough time for this.
If there an element that can't pass through light then there are tremendous application for this,
for real world problems.

Please don't fail me guys, you guys are physicists and telling me there is none? that's broke my heart.
Again please prove it first in mathematics.
 
The question still needs clarification.
 
@mikeph
The question is very simple.
Let say I have a flash light.
Then what element in chemistry maybe or phycist? I'm not sure, that can't pass through light.

Or should you guys define the different types of light first?
May be this is a good starting point?

Before we proceed to that unknown element?
that can't pass through light?
 
What makes you think there is such an element?

And if a bullfrog had wings, it wouldn't bump its a$$ so much. Your "point" is still pointless. What you are seeking doesn't exist.

Aw!. My heart was broken when I found that there's no Santa also . You will get over it eventually.

On the other hand, if we are talking of a high power laser beam and we take a piece of paper and move it slowly in front of the beam.We could say the paper element will not pass trough the light.
Does that make you feel any better.We all know that physics is all about stuff that makes us feel nice inside ,not describing the physical world.
 
@bp_psy

That's interesting dude.
What type of laser beam is that?
Can you post the link here or youtube videos?

Very interesting...!

When the bullfrog can bump the $$$.
Then a lot of frogs will be happy including you.

As you can see no paper passes trough the beam.

I should create that element.
Once we found out that unknown element then some of the major technologies will make them obsolete.

@bp_psy

I'm not interested in burning paper.
I think I should rephrase my phrase.
An element that will deflect light or laser beam.

What, like a mirror?

@bandersnatch
Mirror is not an element.

Think about the Chemistry elements?
 
  • #17
I'm interested on how the paper is burn when it touches the high powered laser beam?
This process is very interesting.
Can someone explain to me this in detail.
Thanks in advanced.

By choosing the wavelength properly, every solid and liquid element reflects light. Probably every gaseous one also, but that probably depends on the pressure etc.

I don't often say this, but this is a stupid question. Perhaps you just don't speak English well and the question that is in your head is good, but as written, this is not a well thought out question.

This entire thread is nonsense, so I'm closing it for now. We will probably delete it later.
