The Gotthard Base Tunnel in the Swiss Alps is poised to be the world’s longest railroad tunnel. At 57 kilometers (35 miles) long, the tunnel will open in December of 2016 and transport more than 200 trains a day, each at an average speed of 250 kilometers per hour (that’s 155 mph).
The tunnel was conceptualized to alleviate the burden of freight traffic on Switzerland’s alpine ecosystem. Over 28 million metric tons of material were moved in its construction, which is more than was required for the Great Pyramid!
Take a look:
Traveling beneath 2,300 meters of solid rock, the trains are connected to two tunnel control centers. In case of an emergency, ventilation systems will turn on, and passengers will be directed to one of the two emergency exits and a parallel relief tunnel.
As someone who is mildly claustrophobic (OK—majorly), I actually wouldn’t mind traveling in this tunnel. Experts have conducted six months of extensive training, and plan another six months’ worth next year.

Grieving couple comforting each other
This response to someone grieving a friend might be the best internet comment ever
When someone is hit with the sudden loss of a friend or loved one, words rarely feel like enough. Yet, more than a decade ago, a wise Redditor named GSnow shared thoughts so profound they still bring comfort to grieving hearts today.
Originally posted around 2011, the now-famous reply was rediscovered when Upvoted, an official Reddit publication, featured it again to remind everyone of its enduring truth. It began as a simple plea for help: “My friend just died. I don't know what to do.”
What followed was a piece of writing that many consider one of the internet’s best comments of all time. It remains shared across social media, grief forums, and personal messages to this day because its honesty and metaphor speak to the raw reality of loss and the slow, irregular path toward healing.
Below is GSnow’s full reply, unchanged, in all its gentle, wave-crashing beauty:
Why this advice still matters
Mental health professionals and grief counselors often describe bereavement in stages or phases, but GSnow’s “wave theory” gives an image more relatable for many. Rather than a linear process, grief surges and retreats—sometimes triggered by a song, a place, or a simple morning cup of coffee.
In recent years, this metaphor has found renewed relevance. Communities on Reddit, TikTok, and grief support groups frequently reshare it to help explain the unpredictable nature of mourning.
Many readers say this analogy helps them feel less alone, giving them permission to ride each wave of grief rather than fight it.
Finding comfort in shared wisdom
Since this comment first surfaced, countless people have posted their own stories underneath it, thanking GSnow and passing the words to others facing fresh heartbreak. It’s proof that sometimes, the internet can feel like a global support group—strangers linked by shared loss and hope.
For those searching for more support today, organizations like The Dougy Center, GriefShare, and local bereavement groups offer compassionate resources. If you or someone you know is struggling with intense grief, please reach out to mental health professionals who can help navigate these deep waters.
When grief comes crashing like the ocean, remember these words—and hang on. There is life between the waves.
