This is a pretty general question, but could it be possble to capture and use an electrons inertia? Or does the Heisenberg uncertainty principle make this just flat out impossible
Thanks for the replies, but Daddy brings up a good point. How do we really know how the universe is expanding, like Nabeshin said,
What undeniable evidence changed our minds in 1997? How do we, "know that our universe is both expanding and accelerating," now? If it is "entirely possible" to...
Thank you for the relpies, sorry for the late response. But havn't we also learned that the universe has contracted before? I think it was just small fluctuations. If this is true then what exactly caused it to do this?
Could it be possible that the universe is just in its expanding state...
For those of you accepting singularity,
When the big bang occurred there was a massive amount of energy exerted.
Did this energy exert a positive acceleration on everything, meaning that it will continue to expand forever? Or did it have a negative acceleration, like throwing a ball up in...
There is new battery tech. called STAIR that can hold 10 times the charge as a battery today, but I am not sure if this is what you are looking for.

Time would tick normally at one second per second just like here on earth, it would only change if you reached near the speed of light, but in that case time would tick slower.
Thanks guys for the help, sorry for such a late response, I've been at the lake and studying for finals the past week. yogi, I'm just going to ask the straight up question, what is the excess radius? I have tried to look into but just can't find out what it is! It would seem like there is a...
I am currently getting ready to end my sophomore year at my high school and have basically come to the decision that i wanted to study astrophysics. Although i still have "time" it seems as though i will run out of it before it is too late, so I am wondering what suggestions people have that i...
By "other problems" do you mean other equations or complications? My guess is probably both, and do you know if there is an example or if you can give me one of a highly symmetric situation? Thanks for the help
Ok, so I now have the equation, thank you guys very much for that by the way, but now can anyone tell me how to apply it? It would seem simple enough as it is looks to serve like a function almost, but for every constant there are numerous other constants involved. What I am asking here is if I...
Alright, so what it is basically saying is that space-time curvature = the Ricci tensor - half the metric tensor * scalar curvature..the only problem I am having is that the Ricci tensor, metric tensor and scalar curvature all break down like the einstein tensor and those break downs break down...
I've been wondering if there is a relationship between the mass of an object and how much it "curves" space-time. I can't seem to find an equation or connection, I have looked at four-momentum but am not certain what it actually calculates. Maybe I just don't know it and there is yet an equation...
This brings up another controversial matter though, because according to Einstein energy and mass are equivalent, so saying that photons have no mass would in turn say that they have no energy, and vise versa, in saying they have energy says they have mass, so either Einstein was "wrong" or...
