What would we see at the speed of light?

What optical effects appear when we accelerate? Could we reach the speed of light? And what would we see when we try to go faster? All these answers in 15 minutes!

The images of this video were simulated with the following effects taken into account:

- Doppler effect (with emission lines spectrum for the background nebula, and blackbody spectrum for the stars)

- Magnification (change of brightness for point-like stars due to aberration and lensing)

- Aberration (change of the perceived direction of light)

Anyway .. who is here just before the night sleep .

I watch tons of physics videos, but I’ve never seen anything like this before. Exact reason I’m a Patreon. This channel is truly something else.

[ginocastro]

Simply out of this world quite literally!! WOW! I'm dizzy just by listening to all the explanations!

1:20 reminds me of "Speed never killed anyone. Suddenly becoming stationary is what gets you."

Man.. life really is stranger than fiction. Absolutely mind blowing.

I'm not much of a commenter, but what a great video. This guy explains some of the most complex stuff in our universe in a realistic, intuitive way while somehow not sacrificing important details. Never seen someone tackle so many tough subjects and explain them all to the level this guy does, one of my favorite channels of all time

[artdonovandesign]

This video ( and this channel) is the result of astonishing dedication and effort.

The scientific intelligence and the ability to effectively communicate the complexities of these subjects are UNMATCHED on YouTube.

Many congratulation, ScienceClic!

'The length of the journey to our destination is shorter than expected'. Finally, a proper explanation of near light speed travel! So few people understand that one can theoretically travel accross the universe in a single lifetime without travelling faster than light.

I love the rain analogy, never really understood why light behaves that way until you'd explained that way. Thanks!

The animation quality in these videos has increased dramatically, this channel deserves a lot more recognition.

[DonPrecedens]

This is the best video about lightspeed and its properties I've watched so far.

Reminded me of a Steven Wright joke. "If I was driving my car at the speed of light and I turned on the headlights, what happens?"

[WMalven]

That graphic showing the rocket moving on the time axis and the second path diverging is the best illustration of the time dilation I've seen. Simple and exceptionally easy to understand.

One of the small details you do that I love is you'll often give a little 4-5 second pause before moving on to the next fact so it can just simmer for a moment in our brains, and it also allows the iconic ScienceClic music to come through a little extra

Terrell-Penrose rotation is the perfect explanation of why I think some portrait paintings/pictures are always looking at me 👀😂

[erasamus]

how did the algorithm take so long to suggest this channel??!
edit: instant Sub

[SpoxGaming]

One of the most, if not the most, detailed and comprehensive videos I've seen on the topic of speed of light. Truly astonished by the effort put into this and the explanation of all the phenomenae that take place. Thank you for this piece of art, you are the hero we need, but do not deserve.

Edit: grammar mistake.

[CaesarPower]

I have stopped this video so many times trying to Google information to make sure I understand it before proceeding with the next info. Amazing video. Thank you

[dianeparsons]

Now this video is a rare gem. Absolutely brilliant, going to look at more now!!!!
