Red Bull Divide and Conquer

Check out this video for the Red Bull Divide and Conquer race.  Looks pretty intense.  The mountain biking looks sick!

A short trip to our closest neighbor

space-shuttle-launch3aI read this thing this morning that was talking about how they found evidence of planets around our closest neighbor galaxy Alpha Centauri.  I didn’t do an assload of research on what I’m about to say, nor am I going to go into all of the logistics of why or why not this is even possible.  The article also claimed it was approximately 5-6 light years away.  To make things easier let’s just say it’s 5 light years away.  None-the-less, I wondered to myself, “How fast does our space shuttle go?”  Some unvarified source on the internet said 17,000 – 18,000 mph.  Which to me sounds like a decent number to work with.  I’ll give the human race the benifit of a doubt and just assume that we will be working with 18,000 mph.  So from that point I wondered to myself,  “How long would it take us to fly to our closest neighbor?”  This is what I came up with:

18,000 mph x 24 hours in a day =  432,000 miles per day

432,000 mpd x 365 days = 157,680,000 miles per year

Let’s just say a lifetime is 70 years.  If that’s the case we could travel this far in a lifetime:

157,680,000 mpy x 70 years = 11,037,600,000 (That’s billion) miles in one lifetime.

That’s pretty impressive.  so just around 11 billion miles in 70 years.  Shit why don’t we at least send an unmanned craft over to Alpha Centauri and see what the hell is up.  However we need to think about how long it will take to get there at our current top speed.  Once again, I have to say the plain and simple truth is the logistics of us maintaining that speed for a lifetime, or even for the person to stay alive for a life time in space is a whole other issue.  Let’s just go with the best case/perfect world senario.  So back to the numbers.

The speed of light: 670,616,629 mph x 24 hours = 16,094,799,096 (That’s billion) mile per day.

16,094,799,096 mpd x 365 days = 5,874,601,670,040 (That’s trillion) miles per year

As I said earlier let’s just say it’s 5 light years to Alpha Centauri.

5,874,601,670,040 mpy x 5 light years = 29,373,008,350,200 (Still trillion) miles

Now let’s see how many lifetimes it would take to get there:

29,373,008,350,200 miles (5 light years) / 11,037,600,000 miles (one lifetime’s distance of travel) = 2661 lifetimes.

And for a little perspective.  If we left today, someone would get there roughly around the year 188,283 AD.
