• Interstellar Travel: Approaching Light Speed

    Is interstellar travel doomed to remain in the realm of science fiction? Sticking to near future space propulsion only, how close can we get to the speed of light? This video looks at the current spacecraft speed records with Apollo 10 holding the record for the fastest manned spacecraft, New Horizons probe for the fastest Earth escape velocity and the Helios probes for the fastest heliocentric velocity. But Solar Probe Plus will beat that when it launches in 2018. While Voyager 1 doesn't set any speed records, it was the first spacecraft to leave the solar system, so therefore the fastest solar system escape velocity by default. For beating these speeds, this video explores what is possible in the near future only, so no antimatter, Alcubierre drives (warp), ramjets, etc... The EM drive...

But there is another way that humanity isn't taking seriously and that is connectome aka sending human consciousness into space on a laser beam and it can help us reach alpha centauri in just four years.

    Can we see things travelling faster than light? Check out Audible: http://bit.ly/AudibleVe Music by Amarante "One Last Thing" http://bit.ly/VeAmarante Awesome animations by http://youtube.com/minutephysics Thanks to Prof. Geraint Lewis for input on earlier drafts of this video. The expanding universe is a complicated place. During inflation the universe expanded faster than light, but that's something that actually happens all the time, it's happening right now. This doesn't violate Einstein's theory of relativity since nothing is moving through space faster than light, it's just that space itself is expanding such that far away objects are receding rapidly from each other. Common sense would dictate that objects moving away from us faster than light should be invisible, but they aren't. ...

The EM drive is left out until it's proven with actual reproducible results in space. Project Daedalus and the updated Project Icarus represent sound concepts for fusion spacecraft. IKAROS was the first successful demonstration of solar sail technology but hopefully the planetary society is not far behind with their LightSail cubsat (not covered in this video). But what appears to have the most potential to reach the nearest star to our own, Proxima Centauri and it's newly discovered planet Proxima b is Breakthrough Starshot. Thousands of super lightweight laser sail nanocraft will be launched into space then the light beamer, a ground based laser array will propel these spacecraft to 20% light speed within minutes. *All sources used in researching this video are listed in the end credits* Music: "Inspired" Kevin MacLeod (incompetech.com) Licensed under Creative Commons: By Attribution 3.0 License http://creativecommons.org/licenses/by/3.0/

Can we see things travelling faster than light? Check out Audible: http://bit.ly/AudibleVe Music by Amarante "One Last Thing" http://bit.ly/VeAmarante Awesome animations by http://youtube.com/minutephysics Thanks to Prof. Geraint Lewis for input on earlier drafts of this video. The expanding universe is a complicated place. During inflation the universe expanded faster than light, but that's something that actually happens all the time, it's happening right now. This doesn't violate Einstein's theory of relativity since nothing is moving through space faster than light, it's just that space itself is expanding such that far away objects are receding rapidly from each other. Common sense would dictate that objects moving away from us faster than light should be invisible, but they aren't. This is because light can travel from regions of space which are superluminal relative to us into regions that are subluminal. So our observable universe is bigger than our Hubble sphere - it's limited by the particle horizon, the distance light could travel to us since the beginning of time as we know it.

These 3 things go "faster" than the speed of light. How's that even possible? Subscribe: http://www.youtube.com/channel/UCj1gf...Want more info?↓ More about the experiment: Marissa Giustina’s research: http://arxiv.org/abs/1511.03190 Advanced scientific note about Doppler: If there is a light moving away from you at constant velocity in static flat (Minkowski) space-time, no matter how red it is, you will never conclude it is going faster than light. But, here I am discussing the conclusions one might come to if you mistakenly use Doppler in the context of the curved space-time of the universe (where there is expansion). Interpreting the huge redshift as a result of the doppler effect, could make one think that galaxies we see are moving away at speeds approaching light speed. And since what we are actually seeing is light from those galaxies from billions of years ago, and given that the universe is expanding, you might be tempted to say that they have since "accelerated" to faster than the speed of light. You might go further and say that there are more distant galaxies that we can't see which are moving away even faster. So you might conclude there are galaxies moving faster than light in the universe. But the redshift isn't from doppler and this "acceleration" of the expanding universe isn't actually causing a true increase in velocity. Sometimes astronomers do say there is a faster than light "recession speed" by pretending the expansion of the universe is causing distant galaxies to move away from each other at a corresponding velocity, but that's misleading. In general relativity, you can actually have an increase in space between objects without causing a corresponding increase in the relatives velocities of those objects.

Is Time Travel Possible? Subscribe: https://goo.gl/GmtyPv Everyone has thought about time travel at least once in their life. Maybe you’ve wanted to go back in time and try to change something from your past. There’s even a lot of science fiction movies out there that involve time travel, or were inspired by time travel in some way or another. But is it really possible to travel back or forward in time? And if it really is possible, what would we have to do in order to make time travel a reality? The very thought about time travel and what it would take to make it a reality is mind-boggling. It is something that scientists, especially astrophysicists, have long thought about. The most fantastic thing? It's probably possible. We should probably start off with the bad news about time travel. We probably can’t travel back in time and watch the Egyptians build the pyramids. However, there are a number of theories that have suggested that it is possible to take a leap forward in time. But going back in time is far more complicated. That’s not saying it’s impossible though. The great 20th century scientist Albert Einstein developed a theory called Special Relativity. While most people think of time as a constant, Einstein showed that time is an illusion; it is relative in that it can vary for different observers depending on your speed through space. The ideas of Special Relativity are very hard to imagine because they aren't about what we experience in everyday life, but other scientists have confirmed this theory. The theory says that space and time are really aspects of the same thing which is called ‘space-time’. There is a speed limit of 300,000 kilometers per second (or 186,000 miles per second) for anything that travels through space-time, and light always travels this speed limit through empty space. So more about this illusion of time, ‘Special Relativity’ says that a surprising thing happens when you move through space-time, especially when your speed relative to other objects is close to the speed of light. Time goes slower for you than for the people you left behind. You won't notice this effect until you return to those stationary people. So as an experiment, let’s say you were 15 years old and you left Earth in a spacecraft traveling at about close to the speed of light, and you celebrated only five birthdays during your space voyage. When you got home at the age of 20, you would find that all your classmates who were the same age as you when you left were 65 years old, retired, and hanging out with their grandchildren! The reason for this is because as time passed more slowly for you, you would have experienced only five years of life, while your classmates will have experienced a full 50 years.

Think your foster kittens can't road trip with you? Think again! As long as their care and temperature remain constant, they can go wherever you go. In this video, I'll show how I travel with kittens, including what to pack and how to feed the babies on a long drive.
