A Man Convicted Against His Will Is Of The Same Opinion Still.

can you explain a bit about the curvature of spacetime or how it's curved?

Thanks for asking!! It’s a little difficult ti picture curved space, so I highly recommend this video, it’s phenomenal at helping you understand how gravity arises from space and time being warped//curved by matter.

I think the above video does a phenomenal job at explaining gravity in terms of warping space and time; definitely watch it. The heavier an object, the more it warps space-time; this means that time gets slowed down with heavier objects, since the space and time become more warped. You may have heard that time flows slower on the earth than it does further up from its surface; time flows faster for astronauts since they experience less of earth’s gravity (since they are further away).

This visualization was the best one I could find? but tbh it’s still hard for pretty much everybody, including the world’s best physicists, to visualize and wrap their head around. Let me know if you have any other questions or need a clarification!! Also, you might want to check out the relativity/general relativity tag on my blog if you want to see some of the other posts i’ve made.

So, our physics teacher has the strange idea of motivating his students by letting each of us present a physical phenomenal we find interesting to our classmates in a 5-minutes-presentation. And now I need something that is interesting for everyone - even people that usually don't care for physics -, but has interesting facts for someone who's interested in it, too (preferably with an easy experiment). You don't happen to have any ideas, do you?

First of all, your professor is awesome for taking the time to do this. Of the top of my mind, the best one I have is Chladni figures.

Basically take a flat metal plate, fix it at the center and spray some fine sand particles on it.

Using a violin bow, gently excite any edge of the plate to magically witness these beautiful normal mode patterns ( known as Chladni patterns/figures ) forming on the plate.

Also notice that by pinching the plate at different points, the pattern obtained changes.

There is a whole lot of physics that goes behind such a simple phenomenon and I dare say we understand it completely. There are lots of questions on these figures that we have no answer for!

Hope this helps with your presentation. Have a good one!
