The concept of ‘relativistic mass’ has been around almost as long as relativity has. But is it a reasonable way to make sense of things?

For many years, some cosmologists embraced the idea of an eternal, steady state universe. But science triumphed over philosophical prejudice.
Up until 2002, we thought that the heaviest stable element was bismuth: #83 on the periodic table. That’s absolutely no longer the case.
The laws of physics obey certain symmetries and defy others. It’s theoretically tempting to add new ones, but reality doesn’t agree.
According to renowned physicist Christophe Galfard, physics can’t explain our universe – yet.

The laws of physics state that you can’t create or destroy matter without also creating or destroying an equal amount of antimatter. So how are we here?
If there really is another version of you out there in a parallel universe, what can that teach us about reality?
A volley of new insights reignites the debate over whether our choices are ever truly our own.
All of the matter and radiation we measure today originated in a hot Big Bang long ago. The Universe was never empty, not even before that.
Particle physicists use gigantic accelerators to investigate the infinitesimal.
Even with quantum teleportation and the existence of entangled quantum states, faster-than-light communication still remains impossible.
Is history decided by discernible laws or does it unfold based on random, unpredictable occurrences?
When it comes to spotting a lie, less is more.
In physics, we reduce things to their elementary, fundamental components, and build emergent things out of them. That’s not the full story.
The multi-leveled constructions of metaphysics are the collective workings of a fantastical virtuality. Did you get that?
JWST has brought us more distant views of the early Universe than ever before. Is the Big Bang, and all of modern cosmology, in trouble?
Physicists just can’t leave an incomplete theory alone; they try to repair it. When nature is kind, it can lead to a major breakthrough.
For generations, physicists have been searching for a quantum theory of gravity. But what if gravity isn’t actually quantum at all?
In our Universe, matter is made of particles, while antimatter is made of antiparticles. But sometimes, the physical lines get real blurry.
When the hot Big Bang first occurred, the Universe reached a maximum temperature never recreated since. What was it like back then?
Einstein called his idea “abominable,” but the world of physics came around to embracing the views of Georges Lemaître.
Recent measurements of subatomic particles don’t match predictions stemming from the Standard Model.
What would become the Big Bang model started from a crucial idea: that the young Universe was denser and hotter.
The classic picture of Jupiter’s great rocky core might be entirely wrong.
If the “self” is not real, then we are slaves to a billiard ball universe, trapped in a nihilistic nightmare in which we cannot change our fate.
Humans won’t survive if we stay on Earth. Michio Kaku explains.

Contrary to common experience, not everything needs a medium to travel through. Overcoming that assumption removes the need for an aether.
Scientists can make substantial progress without fully understanding exactly what they’re doing.
All life forms, anywhere in our Universe, are chemically connected yet completely unique.
There may be a symmetrical interdependence between order and chaos.
