The Valley
in the valley, it’s hot as the sun shines
in the valley, the river is flowing
I do not think this is a sign
all the plants are growing
down in the valley, the animals roam
eating the grass day and night,
many living things call this valley home
because the sun shines and gives its light
int he valley there are all the seasons
winter is snowy, icy, chilly, and cold
spring and fall have warmth and reason
summer is hot, lousy, and uncontrolled
in the valley, the trees are covered with snow
the river turns to ice and does not flow

Is it possible to transfer information faster than the speed of light?
transferring data at faster than light speeds will make communication between planets and solar systems a lot bearable than waiting 4 years for a message to get to the nearest solar system. Faster data transfer might allow for real-time communication between planets. Nothing has been observed by scientists, to travel faster than light, and maybe nothing will ever be observed to travel faster than light. There have been studies to determine if neutrinos can travel faster than light, and some of them even said neutrinos could travel faster than light[1], but the measurements were faulty and not set up the right way. in order to make something go faster than the speed of light, we need to find out if light has mass because mass is closely linked with speed and energy, if light does have mass, there could easily be a particle with less mass than light or we could make one. So does light really have any mass? E=mc² proves that energy can become mass, and light does have a lot of energy. The short answer: no, nick lucid does a good job of explaining why light has no mass in this video:
light has no mass, but can there be something with negative mass?[2] particles with negative mass can actually work with Einstein’s theory of relativity [3]. Some Particles with negative mass are called tachyons.
Tachyons
Tachyons were in Star Trek to explain faster than light travel and real-time communication over very long distances. Tachyons were first proposed by O. M. P. Bilaniuk, V. K. Deshpande, and E. C. G. Sudarshan in 1962, the term they used was “meta-particle”. If tachyons do exist, they would break the law of causality, allowing them to travel back in time[4], allowing us from the future to communicate with the past. If tachyons did travel back in time, why haven’t we seen any transmissions from the future yet? Is it because tachyons don’t exist? or for some other reason maybe? tachyons aren’t the only theorized way to send data faster than light, there are also wormholes.
Wormholes
Wormholes can work with general relativity but they are only a theory. Here is an explanation for wormholes “A wormhole could connect extremely long distances such as a billion light-years or more, short distances such as a few meters, different universes, or different points in time.” [5]. a wormhole can work like a teleporter, linking large distances. If we are to make a wormhole between 2 places it would require an immense amount of energy and the bigger it gets, the more energy it will take, so it might be practical to make a wormhole a few atoms wide to transfer signals through. There are some theories that going through a wormhole could be time travel [6] but it might not. Wormholes aren’t proven to exist and no one really knows if they are real but there is something that is proven and it might help us transfer information faster than the speed of light, quantum entanglement.
Quantum Entanglement
Quantum entanglement is proven to work and scientists can even entangle particles with experements[7]. I can’t explain how quantum entanglement works but Veritasium does a good job at explaining it here. the problem with quantum entanglement is with sending information if you force an entangled particle into a state it breaks the entanglement [8]. Unless more research happens in quantum entanglement we won’t be able to transmit data at faster than light speeds.
In the end, there is no way to transfer data faster than the speed of light at the moment. If more research goes into this topic and more experiments happen then it might be very possible. If I had to guess how we would transmit data at faster than light speeds I think it would be wormholes.

math 10 – week 15
this week in math we learned about solving a system using elimination. To solve a system using elimination you first take the 2 equations: 3x + 4y = 10, -x + 5 = -16. now you should multiply the second equation by 3 to make it -3x and the first equation is 3x so they cancel each other out to get: 4y = 10, +15y = -48(because you multiplied everything by 3 on the second equation). now add the like terms from the equations to get: 19y = -38. now you divide both sides by 19 to get y = -2. now put the -2 into the equation to have 3x + 4(-2) = 10 multiply to get: 3x – 8 = 10. bring the -8 to the other side of the equation to get: 3x = 18. divide both sides by 3 to get x = 6. and that’s how you solve the equation.
math 10 – week 14
this week in math we learned about systems in linear equations. A system in a linear equation is where 2 lines meet. You can solve this by taking the 2 equations, x + 2 = y and 3x + 4y = 1. you need to get a variable by its self on one side of the equation like y in x + 2 = y. Now, you have to put the x + 2 into the other equation in place of the y so you would get 3x + 4(x + 2) = 1 and then expand it to get 3x + 4x + 8 = 1 and add the like terms but put the numbers without a variable to the other side of the equation to get 7x = -7 and now divide to get x = -1. To get the y you need to add the x into one of the equations (the first one is easier) to get -1 + 2 = y and solve to get y = 1.
math 10 – week 13
this week in math we learned how to make 2 points ((7,5) and (6,1)) on a graph into a general equation. First, you need to find the slope of the 2 points, to do this you need to subtract the 2 x’s and 2 y’s from each other but make sure you subtract the second point by the first point. ( so 1-5 and 6-7 to get -4/-1, y goes on top) now you put the slope in front of the x and subtract the x by one of the x points ( -4/-1(x – 7)) and on the other side of the equals sign subtract y by the same point on the y-axis. ( -4/-1(x-7) = y – 5) and now the equation is in point-slope form. to turn it into general form you need to distribute the slope. ( -4x + 28 = y – 5) Move everything on one side of the equation to the other and switch the sing of it, now add the like terms and the equation is in general form.(-4x – y + 23 = 0)
