Time Travel: It’s Been Done Before!

Could we really travel through time? The short answer is yes! That’s right. We all have the ability to leap forward through time, even if we don’t realize it. If you wanted to jump to the future, you can simply go to sleep and wake up a few hours later right? Of course that’s cheating the question. We want to be able to go back and redo those silly mistakes we made many years ago. who doesn’t wish they could go back and talk to their 15-year-old self? Tell them not to make the mistakes you did (or they will). Or perhaps you’d rather travel 500 years into the future and see those flying cars we were promised by the year 2000. Fortunately, time travel is theoretically possible.

In fact there is no law in physics that prevents time travel. That’s right, according to all the laws of physics we know, it’s perfectly plausible to travel through time at will. But as the saying goes, with great power comes great responsibility. Time travel is an extremely dangerous endeavor with devastating consequences, and is also riddled with paradoxes.

For example, what if I travelled back in time and prevented World War II? Sounds like a brilliant idea right? Countless lives would be saved, I’d be hailed as a hero! Not necessarily. Although I’d be saving lives, I’d also be destroying others. What about all the technology that we rely on today that was developed during the war, such as jet engines and nuclear power. In fact the world map could be completely different. We could actually be worse off than simply leaving history as it was.

Another famous time travel paradox is the grandfather paradox, which basically states that if we were to say for instance, I travel back to a time before my parents were born and prevent my grandfather from meeting my grandmother. My parents couldn’t have met and thus, I would never have been born. So how could I have gone back in time to prevent my grandparents from meeting in the first place.

So we can see that time travel could be a bad idea, but let’s say we really want to go back in time, how would we do it? Well first we need to understand how time works.

Time is something we are all very familiar with, we all know what it is, but yet we can’t see it, touch it, we can’t seem to interact with it in any way, we can only observe it. Isaac Newton thought that time was constant and never deviated, which would of course make time travel impossible. Even Einstein believed it was impossible, yet it is his equations that make it possible. Einstein theorized that space and time are inexplicably linked in what he refers to as “space-time”. So in theory, if I was to warp space with something extremely powerful like a black hole, I would also be warping time. While this appears to be true and scientists continue to explore its possibilities, the real possibility for time travel, seems to be in his other theory; Relativity. In fact time travel using relativity isn’t just a theory, it’s actually been done, several times! Now you probably think I’m crazy but the secret seems to be in going extremely fast.

According to Einstein’s theory of general relativity, no object with mass may travel faster than the speed of light, which is an astonishing 299,792,458 metres per second in a vacuum (that’s no air). That’s an incredible 1,080 million kilometres an hour! So according to General Relativity, we can only travel at 99.99% the speed of light. But lets say for instance that I’m sitting at the back of a plane travelling at the speed of light and I walk to the front of the plane from the back at a rate of 10 kilometres an hour. I’ll leave the equations out of this, but that would mean that my speed plus the speed of the plane would mean that I’m travelling at 1,080 million and ten kilometres an hour, which is 10km/h faster than light, right? Wrong. According the theory of relativity, time would actually slow down for me to prevent me from travelling faster than light. Sounds weird doesn’t it.

Of course this scenario would never happen in real life, as I have already said we can’t travel at or faster than the speed of light. In fact you would need more than an infinite supply of fuel to travel faster than light, which is obviously impossible.

So then what is relativity? Einsteins theory of relativity basically states that if I’m driving down the road at 50km/h and drive past someone standing on the side of the road, to them I would appear to be travelling at 50km/h, I’m sure you already know this. However to me in the car, they too would travel past me at 50km/h. But then if someone where to drive beside me in another car travelling at 50km/h, to them I would appear to be completely stationary. Hard to believe? It’s the same thing that makes it look the car driving beside you on the highway sometimes seems to be floating just outside your window. I’ll leave the complicated equations out of this for now, but you can use simple addition and subtraction to confirm this theory. If you’re travelling in the same direction as the object you’re observing, in this case the other car, you subtract your speed from theirs. So 50km/h minus 50km/h is equal to 0km/h. so they would appear to be stationary. If we’re traveling in the opposite direction we add our speed to theirs. So 50km/h plus another 50km/h is equal to 100km/h. So if we drove past the other car at the same speed in the opposite direction, they would appear to be travelling at 100km/h.

So how does all this work, and more importantly, how did they actually manage to travel through time? Well as it turns out, the faster we travel, the slower time will pass. This was proven when scientists placed an atomic clock, which is an extremely accurate clock down to one billionth of a second, on the space shuttle and observed it its behavior. Before launch the clock was perfectly synced with another atomic clock here on earth, and once the shuttle had returned to earth they put the two clocks together. They then discovered the clock from the shuttle was slightly behind the clock that remained on earth. meaning time had past slower for the clock on the shuttle than the clock that remained on Earth.

So basically astronauts are in fact also time travellers. Sergei Krikalev, the current record holder for the longest time spent in space (about 804 days or 2.2 years) is actually half a second behind the rest of the world. furthermore, scientists have actually calculated that if we could orbit the Earth at 99.99% the speed of light for 7 whole years, we would actually land back on earth 500 years in the future. This effect is known as Time Dilation. What a spectacular realisation! Time travel may actually be within our reach after all. The only problem is inventing a machine or vehicle capable of travelling that fast. Unfortunately it looks like that might be just out of our reach for now. We would actually need the power of a whole star to get to that speed.

But what about travelling back in time? So far neither general or special relativity allow for travelling backwards in time and it appears as though no other laws of physics will allow travel to the past. Such travel to the past, as stated above would lead to paradoxes that could result in the collapse of an entire universe, or a completely new one to be formed. This is part of the Many World Interpretation of Quantum Theory. There are other theories to travel both forward and backwards in time such as black holes and wormholes, but I’ll discuss those in the future.

So for now it looks like we could theoretically travel to the future, but unfortunately we can’t go back and tell our younger self not to buy that car from that dodgy looking salesman, or to buy stocks in Apple and Microsoft when they first start out. So we’ll just have to settle for travelling forwards in time at the same rate we always have, and just to wait to see what the future holds

Tips on What You May Need When Travelling – Travel Bags and Accessories

Many people enjoy travelling and will always do so at any available opportunity. Some people travel often because it is part of their job requirements.

You have to choose the type of suitcase or travel/ luggage bag that will give you the greatest flexibility and allows you to travel light.

Traveling With Luggage Bags /Garment Bags for Official/ Business Trips

Most people prefer to fly if they are travelling for official or business purposes such as attending business meetings or going for conferences. In this case you may be spending a night or two away from home, then your best choice of travel bag may be a carry-on bag with wheels or a messenger bag. The messenger bags and rolling bags are available in many sizes ranging from 13″ to 21″. Each of these travel bags lets you travel light because you can fit your computer into your travel bag. The unique design of each bag allows you to comfortably store your notebook/iPad in addition to clothing and personal accessories in the same bag. Each bag has special overnight luggage section that provides enough room for the clothes you need while on your journey. Each bag is perfect for short official/business trips.

The rolling carry-on bags have smooth-rolling wheels and telescoping handle that makes the rolling case a perfect companion for the businessperson on the go.

Some people may prefer to travel with a garment bag, computer /notebook carrying case or a multipurpose handbag (for women). The garment bag is great for protecting clothes while traveling. The clothes stay neat and wrinkle free. The garment bag has multiple pockets and can hold up to 4 garments. It has four interior pockets that provide enough room for shoes and accessories like cosmetic/makeup bags, toiletry bags and curling hot iron cases. It also has one exterior pocket where you can put the book you want to read on the plane or any other thing you want to be handy while you are on the plane. This garment bag is very stylish, lightweight and durable. It has full-length center zipper that gives you easy access to the inside. It also has full exterior zipper closure that ensures that everything inside the bag is secured. When you have packed everything you want inside the bag, you can fold the garment bag into two. The bi-fold bag has two handles that makes it easy to carry. It also has a metal hanging hook that allows you to hang it on a wall. You can then use your multi-purpose handbag or computer/notebook carrying case to carry your computer/iPad.

Some other travelers may prefer to travel with an overnight bag. The overnight bag has zippered main closure with three zippered side pockets and two Velcro end pockets. It has adjustable shoulder strap and carrying handle. It also has a black linen inside lining that makes it great for wiping out and keeping clean.

Travel Accessories- Snoozer – Travel Neck Pillow / Blanket in Velura

Beside the travel/ luggage bags that you need to pack everything you need for your journey, you may consider other travel accessories such as a luxurious Velura covered neck rest that not only carries a soft, easy care Velura 40″ x 60″ blanket inside, but also has an inflatable pillow that allows you to enjoy a warm and comfortable trip. The PVC inflatable pillow is easy to inflate and deflate and the blanket is so soft that it easily folds back into the pillow cover. This snoozer-travel neck pillow/blanket in Velura is a compact, easy to carry travel item that you can use to provide comfort for yourself on any journey. This travel accessory is ideal for business or recreational travelers.

What You May Need When going on Family Vacation

Many families choose to travel by road when on a family vacation; Travelling together in a car is part of the close family experience that every family cherishes and long for every year. Preparing for this long travelling experience for the families can be a sweet challenge for parents, especially when the journey involves very young kids. The thought of how to keep them engaged and entertained all through the long journey can also be daunting.

It is no brainer to say that you need suitcases to pack the family’s clothing and needs while on vacation, The challenge is what type of suitcases do you need. Do you need a suitcase for everyone in the family or do you need to put everyone’s clothing in a common suitcase? Depending on the number in the family and the ages of the kids, you may have a common suitcase for clothing and another for other accessories. Alternatively, each kid can pack his/her accessories in his/her backpack, while you have a common suitcase for everyone. In another arrangement, you can let everyone in the family use a garment bag to pack both his/her clothing and accessories. This is one of the “sweet-bitter” choices parents have to make.

Use A Thermal Cooler Bag to Pack Enough Cold Drinks For Everyone While On The Journey

Depending on the length of the journey you might want to travel with enough cold drinks packed in a thermal cooler bag. The thermal lining of the cooler bags prevents the drinks from absorbing heat as such the drinks will remain cold for a very long time. The idea is for you not to stop to buy cold drinks each time any member of the family wants something cold to drink. Having sufficient cold drinks handy when you need them gives you enough driving time and also lets you stop only when you need to break the journey for any other thing other than just buying some cold drinks.

Make Your Kids Comfortable With Kids’ Travel Accessories

Besides having enough drinks handy for anyone who needs it during the journey, it can also be a challenge to keep the kids comfortable during a very long journey. You can keep your kids comfortable all through the journey by allowing them to use kids’ travel accessories such as travel buddies. Kids’ travel buddies are ultra soft neck pillows that allow kids to snuggle with their buddy while “visiting the land of dreams!” These buddies that are available in different animal characters are perfect for strollers, cars and any other place kids drop off to sleep.

Scosche backSTAGE pro II Vehicle Mount for Tablet PC

Apart from providing cold drinks for your kids when they need them and making them (kids) comfortable while they sleep during the journey, keeping the kids engaged during the course of the journey is another challenge. Some parents allow the children to read their books during the journey, and play their video games when they are tired of reading. These are good ways to keep your kids engaged. Another way is to have them watch videos/movies on iPad while you drive. In this instance, backSTAGE pro II is very suitable. Use the backSTAGE pro II to securely and rugged mount your iPad 2 to the back of any headrest so that your children can enjoy hands free viewing of movies, apps, games while you drive. This device is ideal to keep your family entertained with ease when you are on a long journey. The backstage pro II has a charger that plugs directly into the headrest mount and provides a continuous charge to your iPad 2. It has wireless IR headphones for private listening and a USB port that supports flash drive use for viewing images.

These are some of the things you need to consider when preparing for a business trip or family vacation, to ensure that you have the most comfortable journey whether you travel by air or travel by road with your family on a vacation.
