Homework Statement A student exerts a 30 N[E] force to push a 5 kg brick along a floor that exerts a 20 N[W] friction force. Consider all forces. a. Calculate the acceleration. b. If the force is exerted for 5 seconds, calculate the velocity at the end of the five seconds. c. Calculate the...

Sorry for that. I thought since a theory is basically just an idea, it wouldn't matter. I didn't say it was a fact. I just mentioned it, because it relates to the original post. Feel free to delete it or something.

It was a Documentry uploaded on YouTube on space-time, now slices, and time dilation. I watched it many many months ago. I defiantly wouldn't remember how to find it. Sorry

Honestly my favorite film of the year. I've seen in four times already, and each viewing gets better and better. The soundtrack is by far what makes the movie so spectacular, especially during the wave scene and docking scene.

If there was only one star in the whole universe, and you were placed billions of light years away from it; there would still be gravity. It's defiantly going to be smaller than a micro amount; however, it would still pull no matter where you were in the universe. It would most likely would take...

If the universe lived before; were we there? If the universe lives in the future; will we be there? Just some interesting questions to ponder :)

We do not know the duration of a typical universes lifetime, because the only universe we can observe is our own, and we can't even observe all of it. Our universe right now is to be an estimated 13.8 billion years old; however, that could be only a small chunk of how long they survive for. It...

I read a neat theory on how our universe is like a balloon; however it can save itself from popping by retracting back in. The theory went on how the universe expands from a small scale (big bangs) and contracts from a large scale (end of a universe). So, in theory, there could have been a...

This month Mercury, Venus, Mars, Jupiter, and Saturn will all be visible! http://www.space.com/27898-brightest-planets-december-night-sky.html?adbid=10152482686621466&adbpl=fb&adbpr=17610706465&cmpid=514630_20141203_36578307

We visualize space-time in a two dimensional (flat) image, because it's easier to understand that way. If you stack an infinite amount of those two dimensional space-time fabrics above and below one another, like stacking plates; then you have what would be the the space-time we have around us.

It could be honestly anything. Beyond the event horizon of a black hole; we have no understanding of what happens. The laws of physics are completely torn apart. The singularity could possibly be a one-dimensional point with an empty set. But then again, if it's empty, then there would be no...

No matter what they are trying to get from this, I am still hyped. If the schedule works as planned and they launch the mission by the mid-2030's, then I would only be pushing my late 30's to early 40's. A perfect age for me to join this project ;)

Hey everybody! My name is William, but I prefer to be called Will. I was born, raised, and currently live in the province of Saskatchewan, Canada. I joined this forum, because I have recently discovered I have a huge passion for the physical sciences. The passion is more directed towards...
