Theory of everything: do we really need one?

The quest for a theory of everything – explaining all the forces and particles in the universe – is arguably the holy grail of physics. While each of our main theories of physics works extraordinarily well, they also clash with each other. But do we really need a theory of everything? And are we anywhere near achieving one? Featuring Vlatko Vedral, a professor of physics at the University of Oxford and Chanda Prescod-Weinstein, an assistant professor in physics and astronomy and core faculty in women's and gender studies at the University Of New Hampshire. This episode is presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.

Will we ever have a fundamental theory of life and consciousness?

What’s the difference between a living collection of matter, such as a tortoise, and an inanimate lump of it, such as a rock? They are, after all, both just made up of non-living atoms. The truth is, we don’t really know yet. Life seems to just somehow emerge from non-living parts. Featuring Jim Al-Khalili, professor of physics at the University of Surrey and Sara Imari Walker professor of physics at Arizona State University.

Quantum mechanics: does objective reality exist?

It is hard to shake the intuition that there's a real and objective physical world out there. If I see an umbrella on top of a shelf, I assume you do too. And if I don't look at the umbrella, I expect it to remain there as long as nobody steals it. But the theory of quantum mechanics, which governs the micro-world of atoms and particles, threatens this commonsense view. Featuring Chiara Marletto, Research Fellow of Physics, and Christopher Timpson, Professor of Philosophy of Physics, both at the University of Oxford, and Marcus Huber, Professor of Physics, TU Wien.

Is time an illusion?

Without a sense of time, leading us from cradle to grave, our lives would make little sense. But on the most fundamental level, physicists aren't sure whether the sort of time we experience exists at all. We talk to three experts and find out if time could potentially be moving backwards as well as forwards. Featuring Sean Carroll, Homewood professor of natural philosophy at Johns Hopkins University, Emily Adlam, postdoctoral associate of the philosophy of physics at Western University and Natalia Ares, Royal Society university research fellow at the University of Oxford.

How China cleaned up its air pollution

As Pakistanis and Indians struggle with hazardous air quality, in Beijing – a city once notorious for its smog – the air quality is currently rated as good. Ahead of the 2008 Beijing Olympics, the Chinese government was so concerned about pollution that it introduced temporary restrictions on cars, shut down factories and work on some construction sites. It would take a few more years before the Chinese government implemented a clean air action plan in 2013. Since then, China has achieved a dramatic improvement in its air quality. In this episode, we speak to Laura Wilcox, a professor at the National Centre for Atmospheric Science at the University of Reading in the UK, to understand how China managed to clean up its air pollution. But Wilcox’s recent research uncovered some unintended consequences from this cleaner air for the global climate: the pollution was actually helping to cool the atmosphere and by taking it away, it may have accelerated global warming. This episode was produced by Mend Mariwany, Katie Flood and Gemma Ware. Mixing by Michelle Macklem and theme music by Neeta Sarl.

Pemerintah cairkan BSU: solusi lesunya daya beli masyarakat?

Pemerintah Indonesia kembali menggulirkan program Bantuan Subsidi Upah (BSU) sebagai bagian dari upaya menjaga daya beli masyarakat pekerja di tengah tekanan ekonomi. Program ini mulai dicairkan pada 5 Juni 2025, menyasar para buruh dan pekerja yang memenuhi syarat tertentu sesuai regulasi ketenagakerjaan dan kebijakan ekonomi nasional. BSU ini dirancang sebagai bentuk intervensi fiskal langsung untuk membantu kelompok pekerja yang terdampak dinamika ekonomi seperti deflasi atau menurunnya daya beli masyarakat. Bantuan ini diberikan sebesar Rp300.000 per bulan selama dua bulan (Juni–Juli) dan langsung dicairkan sekaligus sebesar Rp600.000 pada bulan Juni. Pemerintah mengalokasikan dana sebesar Rp10,72 triliun untuk pelaksanaan program BSU tahun ini. Di tengah tantangan seperti inflasi dan ketidakpastian global, pemerintah berharap bantuan semacam ini bisa menjadi stimulan bagi masyarakat supaya tetap bisa menggerakkan roda ekonomi. Apakah pemberian BSU ini benar benar menjadi solusi jitu untuk menggerakkan perekonomian negara yang belakangan dianggap lesu? Dalam episode SuarAkademia terbaru, kami membahas isu ini bersama Jaya Darmawan, peneliti ekonomi dari Center of Economic and Law Studies (CELIOS). Jaya berpendapat BSU menjadi salah satu instrumen andalan pemerintah untuk merespons tekanan ekonomi yang dialami masyarakat kelas pekerja. Meskipun program BSU bermanfaat dalam jangka pendek, ia menganggap besaran bantuannya belum mampu mengimbangi tekanan ekonomi saat ini. Salah satu masalah yang menurut Jaya juga perlu disoroti adalah kriteria kelayakan penerima manfaat. Banyak pekerja tidak memenuhi syarat bantuan karena batasan administratif yang tidak mempertimbangkan kompleksitas kerja informal. kriteria penerima BSU ini membuat pekerja yang ada di sektor informal kerap luput dari jangkauan bantuan sosial, meskipun mereka berada dalam posisi paling rentan secara ekonomi. Meskipun kebijakan pemerintah ini perlu disambut dengan baik, namun Jaya beranggapan langkah-langkah ini masih belum cukup untuk mendorong daya beli masyarakat secara berkelanjutan. Ia berpendapat perlu ada pergeseran arah kebijakan dari sekadar bantuan jangka pendek menuju strategi jangka panjang yang lebih menyeluruh. Fokus kebijakan pemerintah sebaiknya tidak hanya memperbaiki daya beli secara sementara, tetapi juga membuka akses terhadap pekerjaan yang layak dan mendukung pekerja untuk keluar dari sektor informal. Menurutnya, pemerintah perlu memikirkan strategi yang lebih komprehensif untuk menciptakan kebijakan ekonomi yang tidak hanya responsif terhadap krisis, tetapi juga berorientasi pada transformasi sosial dan ekonomi yang berkelanjutan.

Mark Latham in the upper house? A Coalition minority government? The NSW election is nearly upon us and it’s going to be a wild ride

It's a fight for a rapidly vanishing centre, which will make passing bills difficult for whoever wins. Chris Pavlich/Dean Lewins(AAP)We are but weeks away from an election in New South Wales – polling day is on March 23 – and it will be eagerly watched. Not just for the outcome but for the implications for the looming federal election. That’s according to Dr Andy Marks, a political scientist from Western Sydney University, who tells us on the podcast today that this state election outcome may give us some clues on how some global political themes are playing out here in Australia. “It’s not just about state politics. Increasingly the Australian electoral cycles, federally and at the state level, are subject to changes in political dynamics internationally. We’re seeing the erosion of centrist politics around the world […] and that even affects humble New South Wales.” He predicts a weakened Nationals Party will be facing a strong challenge from the Shooters, Fishers and Farmers Party and that One Nation’s Mark Latham is almost a sure bet to win a spot in the NSW upper house. “I do think you’ll see a minority Coalition government returned but the really interesting play is what happens in the upper house. Currently, the Coalition have to deal with two to three independents or minor parties to get stuff over the line,” said Dr Marks. “I think what we’ll see in the coming parliament is that that the ranks of cross-benchers will expand quite dramatically, up to seven to nine cross-benchers. So that makes negotiations pretty fraught. "This is really going to be new territory,” he said. “We’ve got One Nation returning to the fold. Mark Latham, their number one ticket holder in the upper house, will get in. But potentially they’ll get two seats in the upper house. You’ll have an emboldened Shooters and Fishers Party. "So you really have a really broad field and it’s going to mean negotiating the passage of bills will be pretty difficult.” We also talked about: why East Hills (which takes in suburbs like Panania, Condell Park, the Bankstown aerodrome, Padstow, Revesby and others) is the most marginal seat in NSW how a plan to demolish and rebuild two stadiums turned into a political headache for NSW premier Gladys Berejiklian why Michael Daley, who took over from Luke Foley as NSW Labor leader late last year, is only now just making his mark how local issues in rural seats may end up deciding the fate of the state what it all means as we head into the May federal election.

Potensi energi angin di Indonesia begitu besar, mengapa kincirnya harus kecil

ENERGY.GOV/WIKIMEDIA, CC BY-SA Angin punya posisi penting bagi sejarah panjang peradaban manusia. Sekitar 7000 tahun lalu, angin tercatat telah memutar baling-baling kapal di sepanjang Sungai Nil di Mesir. Di Cina, 200 tahun sebelum Masehi, hembusan angin telah memutar kincir sederhana dan membantu petani memompa air. Sejak abad ke-20, angin telah menggerakan turbin dan menghasilkan listrik untuk rumah di Eropa dan Amerika Utara. Selain lebih murah, tenaga angin juga terbukti jauh lebih ramah terhadap lingkungan. Tapi mengapa Indonesia sepertinya sulit melakukan hal yang sama? Apa kita kekurangan angin? Adi Surjosatyo, Guru Besar Departemen Teknik Mesin Universitas Indonesia, mengatakan potensi Indonesia sangat besar. Tapi, menurut dia, selama ini kita telah keliru dalam memandang tenaga angin. Di Eropa, daerah kontinental, turbin angin dibuat besar karena angin besar. Tapi di daerah Indonesia, turbin angin harus kecil karena kondisi udara dan kelembapan air laut membuat angin di Indonesia kecil. Rata-rata kecepatan angin di Indonesia dua kali lebih lemah dari angin di Eropa. Hanya sekitar 2,5 sampai 3 meter per detik. Kecepatan angin rendah, kincirnya pun harus kecil. Itulah yang dilakukan oleh Adi di Kampung Bungin, Muara Gembong, Bekasi. Dia bikin energi terbarukan dari angin untuk mengaliri listrik kampung nelayan tersebut. Satu kincir angin setinggi 11 meter hanya butuh Rp 50 juta. Setelah memasang beberapa kincir di pinggir pantai, biarkan angin yang bekerja sepanjang waktu. Edisi ke-29 Sains Sekitar Kita ini disiapkan oleh Ikhsan Raharjo dan narator Malika. Selamat mendengarkan!

Kenaikan PPN 12 persen: apa dampaknya untuk perekonomian Indonesia?

Kenaikan Pajak Pertambahan Nilai (PPN) menjadi 12% hampir pasti bakal berlaku pada tahun 2025 mendatang. Kenaikkan ini merupakan mandat Undang-Undang Nomor 7 Tahun 2021 tentang Harmonisasi Peraturan Perpajakan (UU HPP). PPN adalah instrumen fiskal yang mentarifi pembelian barang dan jasa hasil industri kepada masyarakat. Selain sudah jadi mandat undang-undang, Menteri Keuangan Sri Mulyani Indrawati mengklaim bahwa penyesuaian tarif ini juga bertujuan untuk meningkatkan daya saing Indonesia secara global, khususnya dengan rata-rata tarif PPN yang diterapkan oleh negara-negara anggota Organisasi untuk Kerja Sama dan Pembangunan Ekonomi (OECD). Saat ini, tarif PPN Indonesia masih lebih rendah dibandingkan rata-rata tarif pajak negara-negara dunia. Di tingkat teknis, Direktorat Jenderal Pajak Kementerian Keuangan sedang mengebut aturan teknis pemberlakuan tarif baru ini. Apakah kenaikan PPN ini akan berdampak terhadap perekonomian Indonesia? Adakah dampak yang akan dirasakan langsung oleh masyarakat? Dalam episode SuarAkademia terbaru, kami membahas isu ini dengan Jaya Darmawan, peneliti ekonomi dari Center of Economic and Law Studies (CELIOS). Jaya mengatakan kebijakan kenaikan PPN menjadi 12% ini mempelihatkan kurangnya sense of crisis dari pemerintah. Sebab situasi ekonomi masyarakat yang sedang sulit. Hal tersebut terlihat dari tren deflasi yang stabil terjadi beberapa bulan terakhir. Jaya berpendapat seharusnya pemerintah melihat situasi ekonomi masyarakat saat ini sebelum memutuskan untuk menaikkan tarif PPN. Meskipun tidak menampik kebijakan ini akan membuat penerimaan negara akan meningkat, namun Jaya melihat kebijakan ini bisa jadi bomerang yang jutru bisa kian memperlambat pertumbuhan ekonomi. Penurunan tersebut karena konsumsi penopang nilai produk domestik bruto Indonesia berpotensi akan mengalami penurunan. Alhasil, target pertumbuhan ekonomi yang dipatok pemerintahan Prabowo-Gibran sebesar 8% hanya menjadi janji kampanye semata tanpa realisasi nyata. Jaya menyarankan agar pemerintah harus mempertimbangkan menerapkan pajak yang adil, alih-alih meningkatkan PPN. Ia menambahkan, sudah banyak jurnal dan hasil riset yang menunjukkan dengan penerapan sistem pajak yang menggunakan prinsip berkeadilan dan tata kelola yang baik justru bisa memberikan negara pemasukan yang lebih banyak daripada menaikkan PPN saat ini.
