If you travelled at the speed of light it'ld take you:

1 second to go around Earth seven and a half times.
3 years to reach the outer limits of our Solar System (The Oort cloud)
4 years to get to Proxima Centuri.
The center of the Milky Way Galaxy - 25,000 years.
The Andromeda Galaxy ( a nice spiral one) - 2,500,000 years.

Invest in wormhole technology now!

Indeed.

As long as we don't develop something like this:

Event Horizon (film)

This movie still scares the living daylights out of me even though I've seen it 3 or 4 times.  :o

1/ Assuming we had that tech,
and 2/ we had the tech to avoid hitting even just pea sized objects ['floating' in space] during our journey.

To get some idea about how far it is to the nearest star (other than the Sun, of course) I remember reading an article many years ago saying that if our entire Solar System was the size of a 5 cent piece (with the orbit of Pluto being the outside of the coin) then the nearest star (Proxima Centauri) would be about 200 feet away.

Wow.  :o

Mars in less than 15 minutes

Yes, wow. The distances are far beyond 'distances'.

I think you would experience far less time. But on the downside, you would put on a lot of weight.

As in: zero time and infinitely fat!

There's nothing out there except death

If we connect the fusion reactor directly to the drive of the DeLorean, Marty, and hook the Ultraglushamic Virtabulator - named after the great German scientist Glusheimer -  into the circuit..... at a speed of EXACTLY 888.1 miles an hour we enter the translight zone instantly and without interruption, thus overcoming the impossibility of time travel!! We can do it, Marty - we can get back to the future in front of the past and long before the future exists!!!  You need to come with me NOW, Marty... after I adjust this Solvaculium Switch .... now where is that small screw driver......

As I travelled, looking back over my shoulder at myself, I knew that I had to be very close to the speed of light.  Travelling at or close to lum1 has some very strange effects, and being able to see oneself is just one of the minor ones. Would I freeze; would my self following me also freeze, and we be locked into staring into each other's eyes for eternity? Maybe that's what hell is; forever locked into looking back at yourself and forward at yourself all at the same time – and making eye contact as well!

Things happened fast then - a great white light erupted in front of me - I looked back over my shoulder in the blink of an eye, to see my self looking at me in amazement, and, somehow, with a sense of longing, perhaps for a future gone before which will now never happen.  His mouth was open as if he wanted to say something.

'I yelled: "Sorry, buddy, but I've got to leave you behind. I'm sorry, Wilson -  I'm sorry!".

I did some easy calculations once.

Even travelling at only 10% of the speed of light -
if your spaceship hit a grain of dust only weighing one microgram -
it would explode with the power of 4 sticks of dynamite on the hull.

Long story short -
it's impossible to survive such speeds.

What if it was in one of President Musk's rockets?

Then it would probably have a “rapid unscheduled disassembly”.

;D

I'm sure one day, Australia will bring America back down to earth

Sounds like complex calculations to me.

Apparently the rate of acceleration needed to reach the speed of light is too great for us to survive. The G-forces would kill us .

Then again, what if we create 'dust deflectors' and 'G-Force eliminators' ?

Easy - 1/2 m v squared.


Dust particles are not magnetically or electrically charged so they can't be deflected.

Don't forget gas clouds that are hotter than the sun. Craft will fry! Humans are a few light years away from leaving the Solar system at least.

Any planet can be encoded at detection by telescope. This is 3D printed and placed in geo-orbital Musk co-ordinated CCP at 3mcg twice daily (or hypersonic Oreshnik take-away).

The Universe doesn't exist. It's just visual effects that as they evolve over decades, produce more and more better quality pixels and dots posing as galaxies 14 billion light years away.
People are starting to catch on, that the Universe has been created on their TV sets in pace with AI technologies, that NASA is now trying to throw Conspiracists off the scent by distorting realities of the Universe by calling it Gravitational Lensing. They couldn't come up with what's at the centre of a Galaxy. If it was just Light, it might empower Religion to claim it is God! So they just left it as nothing and called them Black Holes after reading about a hole in Calcutta long ago. People and Conspiracists aren't stupid you know. They're asking the big questions. So much so, AI NASA &Co have cleverly masked it as Dark Matter (like an unwritten script for sequels to come) and even produced a computer generated picture from a telescope of a universally massive Question Mark ❓
To prove to people it's a big 'dunno' ❓ until the next episode of "WE LIVE IN A CGI MULTI VERSE OF DIGITAL COMMUNICATIONS THAT CAN TRAVEL AT THE SPEED OF LIGHT THROUGH CYBER SPACE'

Rumour has it that the next AI created 'next big discovery' is of Voyager 1 going into a Worm's Hole, never to be seen or heard of again until the remake of Star Trek: the Motion Picture

So. To answer the Question: IF YOU TRAVELLED AT THE SPEED OF LIGHT...

Well, Light does speed up and slow down pending on what it's up against like gravity, gas, particles and so much more! Gravitational lensing shows light that has slowed and been bent. Cosmic voids allow things to move very fast, like expansionism. So the Speed of Light is never a constant. As is the expansion of the universe not a constant. In some parts, it retracts.

...you would see ABSOLUTELY NOTHING if you travelled at the speed of light.

This, I can ABSOLUTELY GUARANTEE you, to be true.
