Bend Your Mind With Special Relativity

Ever dreamed of traveling nearly as fast as light? Zipping across the universe to check out the sights seems like it could be fun. But, not so fast. There are a few things you should know before you jump into your rocket. At near the speed of light, the day-to-day physics we know on Earth need a few modifications. And if you’re thinking Albert Einstein will be entering this equation, you’re right!

We live our daily lives using what scientists call Newtonian physics, as in Isaac Newton, the guy who had the proverbial apple fall on his head. Imagine that you are on a sidewalk, watching your friend walk toward the front of a bus as it drives away. The bus is moving at 30 mph. Your friend walks at 3 mph. To you, your friend is moving at 33 mph — you simply add the two speeds together. (The 30 mph the bus is moving plus 3 mph that your friend is moving inside the bus.) This is a simple example of Newtonian physics.

However, imagine that your friend on the bus turns on a flashlight, and you both measure the speed of its light. You would both measure it to be moving at 670 million mph (or 1 billion kilometers per hour) — this is the speed of light. Even though the flashlight is with your friend on the moving bus, you still both measure the speed of light to be exactly the same. Suddenly you see how Einstein’s physics is different from Newton’s.

This prediction was a key part of Einstein’s special theory of relativity: The speed of light is the same for any observer, no matter their relative speed. This leads to many seemingly weird effects.  

Before talking about those surprising effects, it’s good to take a moment to talk about point of view. For the rest of this discussion, we’ll assume that you’re at rest — sitting in one spot in space, not moving. And your friend is on a rocket ship that you measure to be traveling at 90% the speed of light. Neither of you is changing speed or direction. Scientists give this a fancy name — an “inertial frame of reference.”

With the stage set, now we can talk about a couple of super-weird effects of traveling near the speed of light. Relativity messes with simple things like distance and time, doing stuff that might blow your mind!

Let’s say you have a stick that is 36 inches long (91 centimeters). Your friend on the rocket doesn’t know the stick’s length, so they measure it by comparing it to a ruler they have as they zoom past you. They find your stick is just 16 inches (40 centimeters) long — less than half the length you measured! This effect is called length contraction. And if they were moving even faster, your friend would measure your stick to be even shorter. The cool thing about relativity is that both of those measurements are right! We see these effects in particle physics with fast-moving particles.

If your friend was traveling to our nearest neighbor star, Proxima Centauri, how far would they think it was? From Earth, we measure Proxima Centauri to be 4.2 light-years away (where one light-year is the distance light travels in a year, or about 5.8 trillion miles). However, your friend, who is traveling at 90% the speed of light in the rocket, would measure the distance between Earth and Proxima Centauri to be just over 1.8 light-years.

That’s just length … let’s talk about time!

Now let’s say you and your friend on the rocket have identical synchronized clocks. When your friend reaches Proxima Centauri, they send you a signal, telling you how long their trip took them. Their clock says the trip took just over two years. Remember, they measure the distance to be 1.8 light-years. However, you would see that your clock, which stayed at rest with you, says the trip took 4.7 years — more than twice as long!

This effect is called time dilation — time on moving clocks appears to tick slower.

None of this accounts for your friend accelerating their rocket or stopping at Proxima Centauri. All of this math gets more complicated if you and your friend were speeding up, slowing down, or changing directions. For instance, if your friend slowed down to stop at Proxima Centauri, they would have aged less than you on their trip!

Now you’re ready for a few tips on near-light-speed travel! Watch the video below for more.

Now, if you need to relax a bit after this whirlwind, near-light-speed trip, you can grab our coloring pages of scenes from the video. And if you enjoyed the trip, download a postcard to send to a friend. Finally, if you want to explore more of the wonders of the universe, follow NASA Universe on Facebook and Twitter.

good emotional skills to know 4 college but also in general

this is stuff that i’ve found helpful and am in the process of working on. they may not be achievable for you without help and may not work for your specific circumstance, but this is a list of suggestions that you might be able to think about. i am also not a mental health professional so please do feel free to contradict me!!

self soothing.  having a toolbox to take care of yourself by yourself. bc sometimes nobody else is available and you just gotta put some lotion on, listen to a tune, and go to bed early. 

checking in. checking in with yourself to see if you’re okay. knowing how to alter your strategies when your strategies aren’t working. knowing when your strategies aren’t working. this is just taking some time every day to reflect on what goals you didn’t meet and why and what you can do to fix that.

there’s nothing you “should” be doing. if you get caught up thinking “i should be doing x” that’s false! stop that! “should” be doing better implies that you have some obligation to do whatever it is that you “should” be doing. you don’t owe anybody except yourself. analyze why you think you should be doing that thing and change that into…. “i want to be doing x because…” or “doing x will make me happier, because…”. overall, more productive and less self-shamey. 

disconnecting from the crowd. eating in a crowded dining hall can be stressful! knowing how to be alone in a crowd and stay calm is helpful

being okay with being alone.  tbh college is kind of… being alone a lot, in my experience. even though you’re surrounded by people, a lot of time is spent alone. making friends is hard. your friends have different schedules. you’re busy. shit sucks. we make the best of it.

knowing yourself. this relates to a lot of what i’ve already said but like. knowing your emotional state and knowing what helps trick the monkey brain is helpful. stop repressing your feelings, friends.

talking to strangers. ordering from a menu! paying library fines. going to office hours. asking for a cashier at the register if there isn’t one. ya this is hard. ya you gotta expose yourself. sometimes i just try playing a persona. like this isn’t me ordering a sandwich. this is a cool me who knows how to talk to people who is ordering a sandwich.

you don’t have to be friends with your roommates. you just have to live together in a way that doesn’t make you two hate each other. ideally, you two will coexist in a way that doesn’t interfere with the other’s daily life.

give and taking. on the topic of roommates, sometimes your roommate can be a shitty person, but sometimes you are the shitty person! give a little but if they’re negatively impacting your life, communicate.

communicating during disagreements. explain what your emotions are instead of blaming them. “i feel hurt when you…” or “i feel frustrated when” or “i feel unappreciated when.” if things get heated, ask if you both can take a ten minute break and then come back. and don’t bring up disagreements when the other party is preoccupied or going somewhere. you can legitimately schedule a discussion.

it’s okay to apologize. learning to swallow your pride gets easier each time.

knowing that people work differently than you. some people are not gonna click with you and it’s gonna seem like they have this whole brain process up there that is totally unlike yours. and yeah! that’s how it is. and that’s chill if they aren’t hurting anyone else. work with them and be flexible!! 

comforting people. you will probably/definitely see someone cry! hell if i know how to comfort people. someone please help. but some things i’ve learned are: 1) different people need different things. different people need different things! 2) people need different things at different times. 3) you can ask them what they want and it won’t be weird. 4) apparently a lot of people like hugs? but ask. and it’s okay to not want a hug. 5) just show that you care in some way if you don’t know what they need. i used to think that if somebody needed to tell me what they needed it was a sign that i just didn’t know them well enough and we weren’t compatible or i wasn’t being a good friend. that’s fake! friendship isn’t based off of fitting naturally in every way and making an effort to be good for them is important.

knowing it’s okay to not be liked by everyone. it’s okay if strangers think you’re dumb because you said something dumb in public. you know you’re not dumb. it’s okay if not everybody you meet likes you. it’s okay if you do something cringey. everybody has their own shit to deal with and you will not shatter their world.  grow and move on!

forgiving yourself. i’m trying this new thing where when i feel embarrassed about something i say. out loud. “i forgive myself.” and then i just try to grow from that and move on without getting caught in a spiral of shame.

knowing what you need vs what you want and what is better at the time. what you need: a shower. what you want: to not do that. solution: take a shower! or maybe what you actually need is to go to sleep? but guess what. you probably know what is good for you. the hard part is actually doing it.

realize that building habits is less work than discipline. emotional effort is expended every time you have to make yourself do something. just make it part of your routine and you’ll just think it’s normal to do all the good things! like, for example, i’m trying to make it a habit to eat structured meals instead of a “eat when i’m hungry” thing because i know that makes me skip meals, which is bad!

you won’t be able to do everything. forgive yourself for that. write down  things that are top priority and focus on them. everything else is not important right now and you shouldn’t beat yourself up for not being able to do them.

your health is important. i’m not saying health will solve all your problems. it won’t! but health will cause a lot of your problems to go away. because let’s face it. not sleeping causes a lot of problems. 

it’s okay to ask for help. we say this a lot but it’s hard to internalize it. here’s a thought: there’s so much shame and hesitation about asking for help so by doing that you’re actually being proactive (which is respectable) and mature, and therefore… not weak or stupid. ask for help even before you need it! most people love to help others. and especially take advantage of people who are OFFERING help. for example: counselors at school or TAs. it’s literally their job. they want to do it. and if you don’t want to talk to anybody in real life, my inbox is always open.
