Please remember that my physics is very limited. ↑ I didn't get most of that.
Makes perfect sense. What about the point cosmic dust pointed out?
How can I show that the below two factors balance each other out? Can anyone elaborate on that a little further?
I did use that argument. If these two factors balance each other then we was fully wrong :)
He was arguing that these two factors don't necessarily balance each other.
I'm looking for ways to explain to him why he's wrong (or right). If anyone can show me some calculations or convincing...
I agree. I'm not able to solve it because I studied Architecture. My science education is limited. That's why I posted here to get some answers from you smart people. The poll was added for fun.
My brother and I were discussing fuel consumption which lead to this thought experiment.
Let's say you have two identically shaped spaceships of different masses traveling in outer space where they are not effected by any forces. No wind drag, no friction, no gravity, etc.
Let's assume...
No. Space-time is everywhere and everything. Gravity curves the fabric of the universe and everything in it. When gravity "curves" space-time it does so in a higher dimension. Our 3 dimensional perception of the univierse doesn't change.
Microwaves are radio waves. In the case of microwave ovens, the commonly used radio wave frequency is roughly 2,500 megahertz (2.5 gigahertz). Radio waves in this frequency range have an interesting property: they are absorbed by water, fats and sugars. When they are absorbed they are converted...
We were having tea with the family and my brother and I started wondering if holding the cup will help in cooling the tea.
Lets say you have two identical cups filled with the same amount of the same temperature tea.
You let one just sit and the other you grab with both hands . . . which...
According to Einsteins theory of relativity. Objects gain mass as the approach the speed of light. The closer you get the more the mass increases and the harder it gets to increase the speed.
I never thought about that. A 1 dimensional line can be infinite if we curve it into a circle, something two dimensional. Same way the universe can be infinite in the curved spacetime in higher dimension.
