Thanks for the input.

Is there any way to perform the double slit experiment and see the interference pattern without using a laser? If so, what type of light do you need?

There are so many different types of learning disabilities, so there is no straightforward answer to your question: how would someone classify people with learning disabilities? Someone with Asperger's syndrome would typically have problems interacting with others. Social Anxiety or any...

Thanks everyone.

oooh. I see. Thanks. And when we look at a TV or computer screen is it something with our eyes or the processing of info. in our brains that prevents us from noticing the lines? Or both?

What causes the horizontal lines that move down a computer or TV screen when you video tape it?

Your alarm clock probably went off before the timer in your dream reached zero. When the alarm clock sounded, you were partly aware of the sound, but you were still dreaming, so you interpreted the sound as the "zero" time on the computer game. Your unconscious mind may have made the...

Thanks. That clears it up. But why don't photons have kinetic energy?

Does inertia just mean that it takes energy to move a mass?

Does inertia apply to EVERYTHING in the universe? Even subatomic particles? Or is there a certain mass limit where something no longer has the property of inertia?

The size of a black hole is usually defined as the diameter or radius of the event horizon. You can picture the event horizon as an imaginary sphere around the black hole where anything inside of it can never escape, anything on the borderline can escape only if it is traveling at the speed of...

I think MeJennifer means that if the object we were talking about was something like a galaxy, and the space between us and the galaxy was expanding, it would stretch the wavelenth of light along with it. I read about that in a Scientific American article. I'm not sure how the photons are able...

I enjoyed the reading very much. I understand the math a bit better now.

Thanks, rothenstein. Your thread was enlightening. Robphy, thank you for the formula. I will need to do some research to fully understand it however.

Would it be possible to calculate the time dilation of an object if you only knew how redshifted or blueshifted the light coming from the object was? For example, if you knew the wavelength was redshifted by a factor of 4, or by a certain number of meters, could you determine the time dilation...
