Boiling eggs: Relativity How long does it take to boil an egg? Most people would say it takes about six minutes. However, what most people don’t know is that six minutes isn’t the same for everyone. Time is relative. What do I mean by this? Well, in 1905, Albert Einstein realized that while you’re moving through space, you are also moving through time. Time is the fourth dimension which seems confusing at first, but thinking logically, you would never say “I’ll meet you at 3:30” or “I’ll meet you at the movie theater”. You would instead say “I’ll meet you at the movie theater at 3:30.” While you are sitting down reading this sentence, you are traveling through time at a rate of sixty

If these people wanted to test Einstein’s theory, they could send messages at the start and the end of their boiling process which, for them, would take six minutes. According to the time dilation chart (see Figure 1), when moving at 87% the speed of light, time moves twice as slowly as time on Earth. If the people on the spaceship were moving at this speed, when they sent messages before and after their six minute boiling time, twelve minutes would have passed on Earth. Now you might think “Wow 12 minutes big deal” so if this is the case, consider instead that the people on the spaceship were traveling at 99.5% of the speed of light. The time dilation chart (see Figure 1) shows that at this speed time moves ten times more slowly than it does on Earth. Using this mathematics, you can see that if these people were to do the same experiment at this speed, the people on Earth would believe that it had taken them an hour to boil the …show more content…
This theory states that the speed of light in empty space will always have the same value regardless of the motion of the source or the motion of the observer. (Hewitt 286) Now, keeping this theory in mind, imagine you were on a train that was moving at the speed of light. You think you might have a piece of the hard-boiled egg you just ate in your teeth so you get out your phone and turn on the front camera. Can you see yourself? Einstein says you can because all laws of nature are the same in all uniformly moving frames of reference. This is violated if you can tell you are moving at the speed of light. However, the speed of light is constant so it is moving from you to the mirror at its regular speed. For an outside observer, however, the light seems to be moving twice the speed of light because you are moving at the speed of light and the light is moving at the speed of light relative to you. This scenario contradicts this theory therefore; you can never travel at or beyond the speed of light. You’ll just have to eat your burnt
Two equations were used in this experiment to determine the initial temperature of the hot water. The first equation
To attempt to describe Einstein's Dreams would be like trying to explain magic. For example, imagine that a magician holds a ping-pong ball playfully, transferring it from one hand to the other. The magician invites the audience to examine a red silk kerchief that had been neatly tucked into his jacket's front pocket. He then lays the kerchief flat in his left hand and places the ping-pong ball in that kerchief-covered palm. The magician gathers the four corners of the kerchief together, flings it into the air and lets it fall to the floor. He picks up the kerchief and presents it again to the audience for examination: The ping-pong ball is nowhere to be found. Can you say that, from reading this description, you were full of awe and wonder when you discovered the ping-pong ball's disappearance? I would wager that you were not.

What is time? Is time travel possible? When nothing is changing does time still exits ? Is that really true? Are you real? Metaphysics is a branch of philosophy that is significant to us when questions and other clams bring curiosity about whether things are real or not.
Time is a difficult topic to handle in metaphysics; many problems arise. If you support A-series, which involves change, you are left to wonder the rate at which time passes. I cannot put my support behind static time; time appears to pass and in passing change occurs. The only aspect of time that appears to stay frozen are events in the past. However, events have to change from future to present and then to past before they can become static in the past. Even though there are clear objections to theories about time, I cannot support McTaggart’s bold claim that time is unreal. I can only look at time from my perspective. Ultimately there is so much change that occurs in me and around me as time passes that I cannot view time to be unreal and I am left to disregard McTaggart’s argument.
Variables --------- During the experiments, the water will be heated using different spirit burners containing different alcohols. I will be able to change different parts of the experiment. These are the. Volume of water heated:
This aspect of relativity explained the phenomena of light bending around the sun, predicted black holes as well as the Cosmic Microwave Background Radiation (CMB) -- a discovery rendering fundamental anomalies in the classic Steady-State hypothesis. For his work on relativity, the photoelectric effect and blackbody radiation, Einstein received the Nobel Prize in 1921.
A hot plate is acquired and plugged in and if left to warm up. Fill two beakers with 0.075kg of water and record the temperature using a thermometer and record it. Place one of the beakers onto the hot plate and drop one of the metal objects in. Wait for the water to boil and wait two minutes. Take the object out of the water and drop it into the other beaker. Take the temperature of the beaker and record the rise in temperature.
water has had equal amounts of time for it to heat up, again I will
After the water, has been boiling for 10 minutes, and the temperature inside the test tube has been stable for 5 minutes, record the temperature and remove the thermometer.
Lab 4: Energy Conservation: Hot Stuff!! The purpose of this experiment is to try to find the original temperature of the hot water in the heater using the 60 degrees C thermometer. Use your 60°C thermometer, and any materials available in your laboratory, to determine the temperature of the water in the coffee pot. During this experiment we calculated the original temperature of a heater after it had been cooled down, and we did this by measuring hot, cold, and warm water, with a thermometer that had tape covering 60 degrees and up.
We then put the stopwatch on and left them for half an hour. After we weighed each potato tube and recorded our results. We did the experiment twice. We did this to make sure our results were correct. Preliminary method: We did everything the same as in our other experiment except we
The last part of experiment 5, was learning about specific gravity and temperature. Specific gravity does not have any units, it is unitless. When measuring for the temperature, we used a thermometer to calculate the Celsius of the water, 10% sodium chloride, and isopropyl alcohol. The specific gravity uses a hydrometer to measure the gravity of the liquids. Using the hydrometer, to figure out the measurements we have to look at it from top to bottom. The water for specific gravity was .998 while the temperature of it was 24
The scientific definition of time is a measurement of progress that is relative to an individual’s perception of events (HowStuffWorks.com, 2010). A psychological study proves that these viewpoints are
