What can I do if one of the terminal pins on a LED is broken to 0.4cm, and I can't buy another new one? How can I make the terminal pin longer? Because I can twist wire around it anymore- it is too short. Would soldering works in this case? :confused: :confused: :confused:

I live in Toronto. The winter is getting shorter and shorter. Snow is less and less. We used to have a lot of snow and a very long winter. But this winter(or maybe the last winter), I realized that I didn't see as much snowman on the sidewalk as I did few years ago. It might because of the snow smelts too quick or the snow is actually to icy to make snowman and I can't even grab a snowball sometimes.

But where do those absorbed photon go? Would the Universe eventually be full of light? And Why can't you fill up and pop a box with light?

For example, if you put a book on the table, then would it be harder and harder to lift the book when you are increasing the weight under the table, on the floor? Since more mass means more gravity between two objects

Then how come for regular popsicle (like juice, or the one you buy), the whole thing is sweet? It has suger too. Do they just keep spinning it while freezing?

Does light undestroyable? and it will just keep reflecting to different place? Or will it be absorbed by something? Or will light just dim out on its own?

How about the first native people and the inuit people, which are living in nothern part of Canada or even the north pole? They are not white, but they are really living in a very cold environment.

Then.. What is 1D object?

If you (on Earth) and the other person (in Pluto) are holding one extremely long steel stick. If you move the stick forward, would the person in Pluto be able to feel it right away? If that person can feel the movement right away, it means that your energy is faster than light and it means that Einstein's theory(Light is the fastest) is wrong. What do you think would happen? Just forget about that planets are moving or some other planets are in their way because my point is that they are lightyears apart from each other.

Currently, the furthest "edge" of space we can see is about 15 billion lightyears away from the Earth. That's because we estimated that the universe began in about 15 billion years ago, after the the "big bang". It means that the the furthest stars, which are located 15 billion lightyears away from the Earth are actually the image of the beginning of the universe. No one really knows where the universe ends. Because the image of the beginning of the whole Universe might not be appeared yet. Scientists believe that the Universe is expanding. I think that it might only because more and more "light" of the far star are coming to us after billion and billion years of travel. Please excuse me for any technical error. I learned those from an article.
