Will It Be Possible to Travel to Distant Stars One Day?

interstellar travel

Is it possible to get to extrasolar planetary systems faster than the speed of light? Harold White claims that it is. With his team at NASA, he manufactures a superluminal engine for interstellar travel. For example, such a vessel would arrive in just 2 weeks to the system of Alpha Centauri, which is 4 light years from the Sun.

White’s research is an effort to continue and expand the idea of the Mexican physicist Miguel Alcubierre, which had caused heated debates in the scientific world in 1994. The scientist suggested that the space should “shrink” in front of the spacecraft and expand behind it. The spaceship should behave as if placed inside a “bubble” of the deformed space and (more…)

American Physicists Proved the Existence of Dark Matter Particles

dark matter particlesIn the United States, during the CDMS experiment with underground cryogenic detectors, for the first time scientists managed to obtain direct evidence for the existence of dark matter particles.

According to the American physicists who conducted the experiment, there remains one step before the official confirmation of the discovery of dark matter particles – the so-called “WIMPs”.

Dark matter is an invisible substance, the presence of which can be judged only by its gravitational effects. It does not interact with electromagnetic waves, that is, it does not emit, absorb or reflect any light.

The share of “normal” matter has 4.9% of the mass of the universe, the one of dark matter – 26.8%. Dark matter may consist of (more…)

There Is Not Just One, But Many Universes, States Greek Scientist

multiverseSpecifically, ten in the five hundredth, and in the future it will be possible to create universes in the laboratory. Moreover, we live in ten dimensions without realizing it!

These unbelievable ideas belong to the research team of Dimitris Nanopoulos, professor of physics at the University of Texas and member of the Academy of Athens.

According to the Athens News Agency, Mr. Nanopoulos estimates, based on mathematical equations, that it is possible that there are ten in the five hundredth universes. The theory of supersymmetry and the superstring theory provide that, except of the known four dimensions – three of space (length, width, height) and the time- there are still six or seven, which are “folded” in terribly small space, which means that there are 10 or 11 dimensions in total. “We live in ten dimensions, but do not realize it,” said the scientist.

5 Impressive Facts about the Universe

impressive universeThe universe does not stop amazing us. And not just us! Astronomers often get surprised with things they discover about the origins and the structure of the universe. Read these 5 impressive things about the universe:

1. The Universe is really old

The age of the universe is 13.7 billion years, which is counted from the so-called Big Bang. The truth is that the universe is as old as time, since before the Big Bang there was no time, right?

2. The universe is growing with ever increasing speed

In 1920 the astronomer Edwin Hubble (in honor of whom the famous telescope was named) proved that the universe (more…)

8 mysteries of the Universe that still confront scientists

mysteries of the universeScientists have revealed eight major unanswered questions of the Universe. According to the journal Science they vary from the mystery of dark matter to the query of why the Sun is so hot.

Indeed in some cases even scientists admit that some of these questions probably will not ever be answered. And if they will, it will happen thanks to astronomical observations, explains Robert Coontz. (more…)
