My name is Galbard Bofeyneinton and I'm all alone in a dead planet.

The very famous twin paradox, very closely examined.

We got a duel on our hands boys. Who wins?

We'll be taking a deeper dive into the so called paradox. To get. a dpeer understanding and see what happens with time and space during the accelerated phase, at the end we will attempt to connect this to general relativity, SO COOL RIGHT?

We're in low orbit around our planet. All that's left to do is land. And land we will son.

Light 

Everything dies. Even the stars that shine for you. You are stardust after all.

Nah fr we're looking at spectral lines. But we got dis doe.

We're going to model the atmosphere.

Spectral lines results

Time to simulate the spacecraft's trajectory

I must be a centripetal force because I don't do any work. Wait, you don't know what a centripetal force is? You must be out of the loop.

A photon checks into a hotel. The front desk asks ¡°Do you need help with your luggage?¡± The photon replies, ¡°I don¡¯t have any. I¡¯m travelling light.¡±  No, jokes aside, light (electromagnetic waves) are quite important here.

If you were piloting a ship with him and asked him ¡°Are we going the right way?¡± He¡¯d reply saying ¡°Off course, we are¡±. No, jokes aside, today the topic is navigation in the middle of nowhere.

Oh the gods, what a storm. Took a whole 67 days, but I was able to make it out alive. Not the first time death comes knocking.

I think we may have been transported to the surface of Mercury, because things became unbelievably hot when you walked into the room. No, jokes aside, the planet I'm on is really hot

You came here because you doubt my orbits and want further proof that it's o.k. it's not like you doubt me you just think I might've made a mistake :)

Planetary orbits and how to solve for position given some parameters.

Big time evaluation of my wonderful model

We're going to look at radial velocity curves

I will teach you the planetary orbits, more theoretical and analytical. Hang on my child.
