Does time exist? Developments in physics suggest the non-existence of time is an open possibility, and one that we should take seriously.
SPACE.com invites experts in space exploration, science & technology to provide insightful commentary and informed perspective on news, current events, innovations, big ideas and ongoing research. Expert Voices includes Op-Ed analysis and opinion as well as interesting observations from the field and space exploration efforts around the world.
Next-generation hypersonic missiles that Russia, China and the U.S. are developing do pose a significant threat to national and global security.
When these plumes first reach the surface, giant volcanic eruptions occur — the kind that contributed to the extinction of the dinosaurs 65.5 million years ago.
If the measurement is correct, it is yet another strong signal that there are missing pieces to the physics puzzle of how the universe works.
The Babylonians may have first started applying mathematics to scientific study nearly 3,000 years ago to discover the pattern underlying eclipses, nearly 3,000 years ago.
Over the decades, the Big Bang theory has taken on some pretty heavy challengers. Let's explore those alternatives and why they didn't work.
Over the past few months, Promin Aerospace has proven its concept of a unique self-burning rocket, an idea based on autophagic, or "self-devouring," technology.
Did the graviton, the quantum mechanical force carrier of gravity, flood the cosmos with dark matter before normal matter even had a chance to get started?
In new research, we have spotted a hot, Jupiter-like gas giant in the process of forming around a star about 500 light-years from Earth.
It may be possible to build a real, traversable wormhole, but only if our universe has extra dimensions, a team of physicists has found.
Space-based solar power is one of the technologies to feature in the government's Net Zero Innovation Portfolio.
New miniaturized instruments will help detect pollutant gas sources, from power plants to volcanoes.
On March 4, a lonely, spent rocket booster hit the moon at nearly 6,000 mph. Studies of its crater could reveal new science.
Joining the EU would open up prospects for cooperation in all spheres of politics and business — including the space industry — at the highest level for Ukraine.
When the Psyche mission launches this summer, and when the DART spacecraft crashes into the asteroid Dimorphos this fall, be sure to raise a glass to science.
Ceres is the most dominant member of the asteroid belt but it doesn't look like the other asteroids.
If you've ever been stuck in a nightmare traffic jam, you know that "black hole from which you can never escape" captures the feeling well.
So, why in the name of the cosmos am I LARP-ing Albert Einstein as a 1950s-stye doo-wop group?! I wanted to make you smile in these very tense times.
Albert Einstein saw beyond human tribalism to an enlightened realm of tolerance. We can too: He left us clear directions for how to do it.
