General relativity Theory, spacetime and string theory question

AI Thread Summary
The discussion revolves around a high school student's request for a simplified explanation of general relativity, spacetime, and string theory due to confusion from their teacher's explanation. General relativity describes gravity as the curvature of spacetime caused by mass, while spacetime combines the three dimensions of space with the dimension of time into a single continuum. String theory proposes that fundamental particles are not point-like but rather one-dimensional "strings" that vibrate at different frequencies, potentially unifying all forces of nature. Participants suggest that the student should conduct some research to better understand these concepts before seeking further clarification. Engaging with the material independently is emphasized as essential for learning.

General relativity Theory, spacetime and string theory question.. Please Help!

Alright, I am a high school student and my teacher just introduced "the General theory of relativity, spacetime and the Super string theory" to us, but he explained those in some weird way that none of us understood quite well. Can someone please explain these to me, please?? I have a paper that is due is 24 hours. Someone please help!

1. What does the General theory of relativity says in PLAIN English?

2. What does Einstein mean by SPACETIME-- In general English please

3. What is the string theory? What does it really say?

Come on, guys. Someone answer the question and be a pal... Please.
 


Have you considered actually doing some research yourself? The point of writing a paper is for you to go learn about the subject. Even Wikipedia should get you started. Do some reading, then ask more specific questions.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
